1 2334 131 TWELVE-WEEK YOGA VS. AEROBIC CYCLING INITIATION IN SEDENTARY HEALTHY SUBJECTS: A BEHAVIORAL AND MULTIPARAMETRIC INTERVENTIONAL PET/MR STUDY. INTERVENTIONAL YOGA STUDIES WITH AN ACTIVE CONTROL GROUP REMAIN SCARCE AND ARE IMPORTANT TO CLARIFY THE UNDERLYING NEUROBIOLOGY. WE CONDUCTED AN INTERVENTIONAL STUDY IN HEALTHY CONTROLS USING SIMULTANEOUS POSITRON EMISSION TOMOGRAPHY/MAGNETIC RESONANCE (PET/MR) IMAGING AND PSYCHOMETRIC SCALES. THIRTY HEALTHY, FEMALE VOLUNTEERS (28.4 +/- 8.4 YEARS) PARTICIPATED AND WERE RANDOMLY ASSIGNED TO A 12-WEEK YOGA OR INDOOR CYCLING INTERVENTION. BEFORE AND AFTER THE INTERVENTION, [(18)F]FDG AND [(11)C]UCB-J PET WAS PERFORMED ON A SIMULTANEOUS GE SIGNA PET/MR WITH VOLUMETRIC IMAGING. PSYCHOMETRIC SCALES WERE EVALUATED ON AFFECT, MINDFULNESS, STRESS, WORRYING, SELF-COMPASSION, AND INTEROCEPTIVE AWARENESS. YOGA SUBJECTS SCORED HIGHER ON INTEROCEPTIVE AWARENESS COMPARED TO BASELINE (P < 0.001). COGNITIVE (P = 0.009) AND OVERALL COGNITIVE FUNCTIONING (P = 0.01) IMPROVED AFTER THE YOGA INTERVENTION COMPARED TO THE CYCLING GROUP. WE DID NOT OBSERVE SIGNIFICANT DIFFERENCES IN GLUCOSE METABOLISM, SYNAPTIC DENSITY, OR GRAY MATTER (GM) VOLUME. THE INDOOR CYCLING GROUP DID NOT SHOW CHANGES IN PSYCHOMETRIC VARIABLES, BUT SIGNIFICANT INCREASES IN RELATIVE GLUCOSE METABOLISM WERE OBSERVED IN THE PARAHIPPOCAMPAL/FUSIFORM GYRUS AND CEREBELLUM (P < 0.001). IN CONCLUSION, 12 WEEKS OF YOGA PRACTICE HAS SIGNIFICANT EFFECTS ON INTEROCEPTIVE AWARENESS AND PERCEIVED COGNITIVE FUNCTION IN STARTERS. LONGER INTERVENTIONS AND/OR HIGHER FREQUENCY OF YOGA PRACTICE MAY BE NEEDED TO DETECT CEREBRAL METABOLIC AND/OR MORPHOLOGIC EFFECTS ON THE MACROSCOPIC LEVEL.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
2 1555  47 LONG-TERM ASHTANGA YOGA PRACTICE DECREASES MEDIAL TEMPORAL AND BRAINSTEM GLUCOSE METABOLISM IN RELATION TO YEARS OF EXPERIENCE. BACKGROUND: YOGA IS INCREASINGLY POPULAR WORLDWIDE WITH SEVERAL PHYSICAL AND MENTAL BENEFITS, BUT THE UNDERLYING NEUROBIOLOGY REMAINS UNCLEAR. WHEREAS MANY STUDIES HAVE FOCUSED ON PURE MEDITATIONAL ASPECTS, THE TRIAD OF YOGA INCLUDES MEDITATION, POSTURES, AND BREATHING. WE CONDUCTED A CROSS-SECTIONAL STUDY COMPARING EXPERIENCED YOGA PRACTITIONERS TO YOGA-NAIVE HEALTHY SUBJECTS USING A MULTIPARAMETRIC 2 X 2 DESIGN WITH SIMULTANEOUS POSITRON EMISSION TOMOGRAPHY/MAGNETIC RESONANCE (PET/MR) IMAGING. METHODS: (18)F-FDG PET, MORPHOMETRIC AND DIFFUSION TENSOR IMAGING, RESTING STATE FMRI, AND MR SPECTROSCOPY WERE ACQUIRED IN 10 EXPERIENCED (4.8 +/- 2.3 YEARS OF REGULAR YOGA EXPERIENCE) YOGA PRACTITIONERS AND 15 MATCHED CONTROLS IN REST AND AFTER A SINGLE PRACTICE (YOGA PRACTICE AND PHYSICAL EXERCISE, RESPECTIVELY). RESULTS: IN REST, DECREASED REGIONAL GLUCOSE METABOLISM IN THE MEDIAL TEMPORAL CORTEX, STRIATUM, AND BRAINSTEM WAS OBSERVED IN YOGA PRACTITIONERS COMPARED TO CONTROLS (P < 0.0001), WITH A SIGNIFICANT INVERSE CORRELATION OF RESTING PARAHIPPOCAMPAL AND BRAINSTEM METABOLISM WITH YEARS OF REGULAR YOGA PRACTICE (RHO < - 0.63, P < 0.05). A SINGLE YOGA PRACTICE RESULTED IN SIGNIFICANT HYPERMETABOLISM IN THE CEREBELLUM (P < 0.0001). NONE OF THE MR MEASURES DIFFERED, BOTH AT REST AND AFTER INTERVENTION. CONCLUSIONS: EXPERIENCED YOGA PRACTITIONERS SHOW REGIONAL LONG-TERM DECREASES IN GLUCOSE METABOLISM RELATED TO YEARS OF PRACTICE. TO ELUCIDATE A POTENTIAL CAUSALITY, A PROSPECTIVE LONGITUDINAL STUDY IN YOGA-NAIVE INDIVIDUALS IS WARRANTED.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
3 1695  29 P300 FOLLOWING FOUR VOLUNTARILY REGULATED YOGA BREATHING PRACTICES AND BREATH AWARENESS. ATTENTION WAS INFLUENCED BY YOGA BREATHING IN PREVIOUSLY PUBLISHED RESEARCH. EACH YOGA BREATHING PRACTICE UNIQUELY MODIFIES SPECIFIC BREATH CHARACTERISTICS. DIFFERENCES IN THE STUDY DESIGNS, ASSESSMENT METHODS AND INTERVENTIONS RESULTED IN DIFFICULTY IN COMPARING EFFECTS BETWEEN YOGA BREATHING PRACTICES. THIS STUDY AIMED (I) TO COMPARE FOUR YOGA BREATHING PRACTICES ON ATTENTION USING AN AUDITORY ODDBALL TASK AND (II) TO DETERMINE CARDIAC AUTONOMIC ACTIVITY ASSOCIATED WITH ATTENTION USING HEART RATE VARIABILITY. P300 EVENT RELATED POTENTIAL WAS RECORDED SIMULTANEOUSLY WITH HEART RATE VARIABILITY BEFORE AND AFTER 18-MINUTE PERIODS EACH OF (I) HIGH FREQUENCY YOGA BREATHING (WITH INCREASED BREATH FREQUENCY), (II) BELLOWS YOGA BREATHING (WITH INCREASED DEPTH OF RESPIRATION), (III) ALTERNATE NOSTRIL YOGA BREATHING (WITH ALTERNATE NOSTRIL PATENCY), (IV) BUMBLEBEE YOGA BREATHING (WITH PROLONGED EXHALE), (V) BREATH AWARENESS (WITH ATTENTION TO THE BREATH) AND (VI) QUIET SEATED REST AS CONTROL IN 38 YOGA EXPERIENCED MALES (AVERAGE AGE +/- SD; 24.08 +/- 4.01 YEARS). THE SIX SESSIONS WERE ON SEPARATE, RANDOMLY ALLOCATED DAYS. THE P300 PEAK AMPLITUDE RECORDED AT PZ WAS SIGNIFICANTLY INCREASED AFTER FOUR YOGA BREATHING PRACTICES (BONFERRONI ADJUSTED POST-HOC TESTS, REPEATED MEASURES ANOVA). NO SIGNIFICANT CHANGES WERE NOTED IN HEART RATE VARIABILITY FOLLOWING YOGA BREATHING OR CONTROL SESSIONS. THESE FINDINGS SUGGEST THAT THE FOUR YOGA BREATHING PRACTICES INCREASE THE ATTENTIONAL NEURAL RESOURCES ENGAGED FOR THIS AUDITORY ODDBALL TASK, IRRESPECTIVE OF THE CHARACTERISTIC OF BREATH UNIQUELY REGULATED IN THE FOUR YOGA BREATHING PRACTICES.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
4 2371  32 WHAT HAS NEUROIMAGING TAUGHT US ON THE NEUROBIOLOGY OF YOGA? A REVIEW. YOGA IS BECOMING INCREASINGLY POPULAR WORLDWIDE, WITH SEVERAL IMPLICATED PHYSICAL AND MENTAL BENEFITS. HERE WE PROVIDE A COMPREHENSIVE AND CRITICAL REVIEW OF THE RESEARCH GENERATED FROM THE EXISTING NEUROIMAGING LITERATURE IN STUDIES OF YOGA PRACTITIONERS. WE REVIEWED 34 INTERNATIONAL PEER-REVIEWED NEUROIMAGING STUDIES OF YOGA USING MAGNETIC RESONANCE IMAGING (MRI), POSITRON EMISSION TOMOGRAPHY (PET), OR SINGLE-PHOTON EMISSION COMPUTED TOMOGRAPHY (SPECT): 11 MORPHOLOGICAL AND 26 FUNCTIONAL STUDIES, INCLUDING THREE STUDIES THAT WERE CLASSIFIED AS BOTH MORPHOLOGICAL AND FUNCTIONAL. CONSISTENT FINDINGS INCLUDE INCREASED GRAY MATTER VOLUME IN THE INSULA AND HIPPOCAMPUS, INCREASED ACTIVATION OF PREFRONTAL CORTICAL REGIONS, AND FUNCTIONAL CONNECTIVITY CHANGES MAINLY WITHIN THE DEFAULT MODE NETWORK. THERE IS QUITE SOME VARIABILITY IN THE NEUROIMAGING FINDINGS THAT PARTIALLY REFLECTS DIFFERENT YOGA STYLES AND APPROACHES, AS WELL AS SAMPLE SIZE LIMITATIONS. DIRECT COMPARATOR GROUPS SUCH AS PHYSICAL ACTIVITY ARE SCARCELY USED SO FAR. FINALLY, HYPOTHESES ON THE UNDERLYING NEUROBIOLOGY DERIVED FROM THE IMAGING FINDINGS ARE DISCUSSED IN THE LIGHT OF THE POTENTIAL BENEFICIAL EFFECTS OF YOGA.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
5  690  30 EFFECT OF COMBINED YOGA AND TRANSCRANIAL DIRECT CURRENT STIMULATION INTERVENTION ON WORKING MEMORY AND MINDFULNESS. TRANSCRANIAL DIRECT STIMULATION, A NON-INVASIVE NEUROSTIMULATION TECHNIQUE FOR MODULATING CORTICAL EXCITABILITY, AND YOGA HAVE BOTH RESPECTIVELY BEEN SHOWN TO POSITIVELY AFFECT COGNITION. WHILE PRELIMINARY RESEARCH HAS SHOWN THAT COMBINED TRANSCRANIAL DIRECT STIMULATION AND MEDITATION MAY HAVE SYNERGISTIC EFFECTS ON MOOD AND COGNITION, THIS WAS THE FIRST STUDY TO EXPLORE THE COMBINATION OF TRANSCRANIAL DIRECT STIMULATION AND YOGA. TWENTY-TWO HEALTHY VOLUNTEERS WITH A REGULAR YOGA PRACTICE WERE RANDOMIZED TO RECEIVE EITHER ACTIVE TRANSCRANIAL DIRECT STIMULATION (ANODAL LEFT, CATHODAL RIGHT DORSOLATERAL PREFRONTAL CORTEX) FOLLOWED BY YOGA INTERVENTION OR SHAM TRANSCRANIAL DIRECT STIMULATION FOLLOWED BY YOGA INTERVENTION A DOUBLE-BLIND, CROSS-OVER DESIGN OVER TWO SEPARATE INTERVENTION DAYS. OUTCOME MEASURES INCLUDED WORKING MEMORY PERFORMANCE, MEASURED WITH THE N-BACK TASK AND MINDFULNESS STATE, MEASURED WITH THE TORONTO MINDFULNESS SCALE, AND WERE CONDUCTED OFFLINE, WITH PRE-POST ASSESSMENTS. TWENTY PARTICIPANTS COMPLETED BOTH DAYS OF THE INTERVENTION. ACTIVE TRANSCRANIAL DIRECT STIMULATION DID NOT HAVE A SIGNIFICANT EFFECT ON WORKING MEMORY OR LEVELS OF MINDFULNESS. THERE WAS A SIGNIFICANT PLACEBO EFFECT, WITH BETTER PERFORMANCE ON DAY 1 OF THE INTERVENTION, IRRESPECTIVE OF WHETHER PARTICIPANTS RECEIVED ACTIVE OR SHAM TRANSCRANIAL DIRECT STIMULATION. THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN ACTIVE VERSUS SHAM TRANSCRANIAL DIRECT STIMULATION CONCERNING WORKING MEMORY PERFORMANCE AND MINDFULNESS, WHICH MAY BE ACCOUNTED BY THE SMALL SAMPLE SIZE, THE TRANSIENT NATURE OF THE INTERVENTION, THE FACT THAT YOGA AND TRANSCRANIAL DIRECT STIMULATION CONCERNING WERE NOT CONDUCTED SIMULTANEOUSLY, AND THE SPECIFIC SITE OF STIMULATION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
6 1472  28 INSULAR CORTEX MEDIATES INCREASED PAIN TOLERANCE IN YOGA PRACTITIONERS. YOGA, AN INCREASINGLY POPULAR DISCIPLINE AMONG WESTERNERS, IS FREQUENTLY USED TO IMPROVE PAINFUL CONDITIONS. WE INVESTIGATED POSSIBLE NEUROANATOMICAL UNDERPINNINGS OF THE BENEFICIAL EFFECTS OF YOGA USING SENSORY TESTING AND MAGNETIC RESONANCE IMAGING TECHNIQUES. NORTH AMERICAN YOGIS TOLERATED PAIN MORE THAN TWICE AS LONG AS INDIVIDUALLY MATCHED CONTROLS AND HAD MORE GRAY MATTER (GM) IN MULTIPLE BRAIN REGIONS. ACROSS SUBJECTS, INSULAR GM UNIQUELY CORRELATED WITH PAIN TOLERANCE. INSULAR GM VOLUME IN YOGIS POSITIVELY CORRELATED WITH YOGA EXPERIENCE, SUGGESTING A CAUSAL RELATIONSHIP BETWEEN YOGA AND INSULAR SIZE. YOGIS ALSO HAD INCREASED LEFT INTRAINSULAR WHITE MATTER INTEGRITY, CONSISTENT WITH A STRENGTHENED INSULAR INTEGRATION OF NOCICEPTIVE INPUT AND PARASYMPATHETIC AUTONOMIC REGULATION. YOGIS, AS OPPOSED TO CONTROLS, USED COGNITIVE STRATEGIES INVOLVING PARASYMPATHETIC ACTIVATION AND INTEROCEPTIVE AWARENESS TO TOLERATE PAIN, WHICH COULD HAVE LED TO USE-DEPENDENT HYPERTROPHY OF INSULAR CORTEX. TOGETHER, THESE FINDINGS SUGGEST THAT REGULAR AND LONG-TERM YOGA PRACTICE IMPROVES PAIN TOLERANCE IN TYPICAL NORTH AMERICANS BY TEACHING DIFFERENT WAYS TO DEAL WITH SENSORY INPUTS AND THE POTENTIAL EMOTIONAL REACTIONS ATTACHED TO THOSE INPUTS LEADING TO A CHANGE IN INSULAR BRAIN ANATOMY AND CONNECTIVITY.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
7 1972  35 SHORT-TERM SAHAJA YOGA MEDITATION TRAINING MODULATES BRAIN STRUCTURE AND SPONTANEOUS ACTIVITY IN THE EXECUTIVE CONTROL NETWORK. INTRODUCTION: WHILE CROSS-SECTIONAL STUDIES HAVE SHOWN NEURAL CHANGES IN LONG-TERM MEDITATORS, THEY MIGHT BE CONFOUNDED BY SELF-SELECTION AND POTENTIAL BASELINE DIFFERENCES BETWEEN MEDITATORS AND NON MEDITATORS. PROSPECTIVE LONGITUDINAL STUDIES OF THE EFFECTS OF MEDITATION IN NAIVE SUBJECTS ARE MORE CONCLUSIVE WITH RESPECT TO CAUSAL INFERENCES, BUT RELATED EVIDENCE IS SO FAR LIMITED. METHODS: HERE, WE ASSESSED THE EFFECTS OF A 4-WEEK SAHAJA YOGA MEDITATION TRAINING ON GRAY MATTER DENSITY AND SPONTANEOUS RESTING-STATE BRAIN ACTIVITY IN A GROUP OF 12 MEDITATION-NAIVE HEALTHY ADULTS. RESULTS: COMPARED WITH 30 CONTROL SUBJECTS, THE PARTICIPANTS TO MEDITATION TRAINING SHOWED INCREASED GRAY MATTER DENSITY AND CHANGES IN THE COHERENCE OF INTRINSIC BRAIN ACTIVITY IN TWO ADJACENT REGIONS OF THE RIGHT INFERIOR FRONTAL GYRUS ENCOMPASSING THE ANTERIOR COMPONENT OF THE EXECUTIVE CONTROL NETWORK. BOTH THESE MEASURES CORRELATED WITH SELF-REPORTED WELL-BEING SCORES IN THE MEDITATION GROUP. CONCLUSIONS: THE SIGNIFICANT IMPACT OF A BRIEF MEDITATION TRAINING ON BRAIN REGIONS ASSOCIATED WITH ATTENTION, SELF-CONTROL, AND SELF-AWARENESS MAY REFLECT THE ENGAGEMENT OF COGNITIVE CONTROL SKILLS IN SEARCHING FOR A STATE OF MENTAL SILENCE, A DISTINCTIVE FEATURE OF SAHAJA YOGA MEDITATION. THE MANIFOLD IMPLICATIONS OF THESE FINDINGS INVOLVE BOTH MANAGERIAL AND REHABILITATIVE SETTINGS CONCERNED WITH WELL-BEING AND EMOTIONAL STATE IN NORMAL AND PATHOLOGICAL CONDITIONS.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
8  368  29 AUTONOMIC CHANGES IN BRAHMAKUMARIS RAJA YOGA MEDITATION. THIS REPORT PRESENTS THE CHANGES IN VARIOUS AUTONOMIC AND RESPIRATORY VARIABLES DURING THE PRACTICE OF BRAHMAKUMARIS RAJA YOGA MEDITATION. THIS PRACTICE REQUIRES CONSIDERABLE COMMITMENT AND INVOLVES CONCENTRATED THINKING. 18 MALES IN THE AGE RANGE OF 20 TO 52 YEARS (MEAN 34.1 +/- 8.1), WITH 5-25 YEARS EXPERIENCE IN MEDIATION (MEAN 10.1 +/- 6.2), PARTICIPATED IN THE STUDY. EACH SUBJECT WAS ASSESSED IN THREE TEST SESSIONS WHICH INCLUDED A PERIOD OF MEDITATION, AND ALSO IN THREE CONTROL (NON-MEDIATION) SESSIONS, WHICH INCLUDED A PERIOD OF RANDOM THINKING. GROUP ANALYSIS SHOWED THAT THE HEART RATE DURING THE MEDITATION PERIOD WAS INCREASED COMPARED TO THE PRECEDING BASELINE PERIOD, AS WELL AS COMPARED TO THE VALUE DURING THE NON-MEDITATION PERIOD OF CONTROL SESSIONS. IN CONTRAST TO THE CHANGE IN THE HEART RATE, THERE WAS NO SIGNIFICANT CHANGE DURING MEDITATION, FOR THE GROUP AS A WHOLE, IN PALMAR GSR, FINGER PLETHYSMOGRAM AMPLITUDE, AND RESPIRATORY RATE. ON AN INDIVIDUAL BASIS, CHANGES WHICH MET THE FOLLOWING CRITERIA WERE NOTED: (1), CHANGES WHICH WERE GREATER DURING MEDITATION (COMPARED TO ITS PRECEDING BASELINE) THAN CHANGES DURING POST MEDITATION OR NON-MEDITATION PERIODS (ALSO COMPARED TO THEIR PRECEDING BASELINE); (2), CHANGES WHICH OCCURRED CONSISTENTLY DURING THE THREE REPEAT SESSIONS OF A SUBJECT AND (3), CHANGES WHICH EXCEEDED ARBITRARILY-CHOSEN CUT-OFF POINTS (DESCRIBED AT LENGTH BELOW). THIS INDIVIDUAL LEVEL ANALYSIS REVEALED THAT CHANGES IN AUTONOMIC VARIABLES SUGGESTIVE OF BOTH ACTIVATION AND RELAXATION OCCURRED SIMULTANEOUSLY IN DIFFERENT SUBDIVISIONS OF THE AUTONOMIC NERVOUS SYSTEM IN A SUBJECT. APART FROM THIS, THERE WERE DIFFERENCES IN PATTERNS OF CHANGE AMONG THE SUBJECTS WHO PRACTISED THE SAME MEDITATION.(ABSTRACT TRUNCATED AT 250 WORDS)	1993	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
9 1670  27 NEUROPROTECTIVE EFFECTS OF YOGA PRACTICE: AGE-, EXPERIENCE-, AND FREQUENCY-DEPENDENT PLASTICITY. YOGA COMBINES POSTURES, BREATHING, AND MEDITATION. DESPITE REPORTED HEALTH BENEFITS, YOGA'S EFFECTS ON THE BRAIN HAVE RECEIVED LITTLE STUDY. WE USED MAGNETIC RESONANCE IMAGING TO COMPARE AGE-RELATED GRAY MATTER (GM) DECLINE IN YOGIS AND CONTROLS. WE ALSO EXAMINED THE EFFECT OF INCREASING YOGA EXPERIENCE AND WEEKLY PRACTICE ON GM VOLUME AND ASSESSED WHICH ASPECTS OF WEEKLY PRACTICE CONTRIBUTED MOST TO BRAIN SIZE. CONTROLS DISPLAYED THE WELL DOCUMENTED AGE-RELATED GLOBAL BRAIN GM DECLINE WHILE YOGIS DID NOT, SUGGESTING THAT YOGA CONTRIBUTES TO PROTECT THE BRAIN AGAINST AGE-RELATED DECLINE. YEARS OF YOGA EXPERIENCE CORRELATED MOSTLY WITH GM VOLUME DIFFERENCES IN THE LEFT HEMISPHERE (INSULA, FRONTAL OPERCULUM, AND ORBITOFRONTAL CORTEX) SUGGESTING THAT YOGA TUNES THE BRAIN TOWARD A PARASYMPATICALLY DRIVEN MODE AND POSITIVE STATES. THE NUMBER OF HOURS OF WEEKLY PRACTICE CORRELATED WITH GM VOLUME IN THE PRIMARY SOMATOSENSORY CORTEX/SUPERIOR PARIETAL LOBULE (S1/SPL), PRECUNEUS/POSTERIOR CINGULATE CORTEX (PCC), HIPPOCAMPUS, AND PRIMARY VISUAL CORTEX (V1). COMMONALITY ANALYSES INDICATED THAT THE COMBINATION OF POSTURES AND MEDITATION CONTRIBUTED THE MOST TO THE SIZE OF THE HIPPOCAMPUS, PRECUNEUS/PCC, AND S1/SPL WHILE THE COMBINATION OF MEDITATION AND BREATHING EXERCISES CONTRIBUTED THE MOST TO V1 VOLUME. YOGA'S POTENTIAL NEUROPROTECTIVE EFFECTS MAY PROVIDE A NEURAL BASIS FOR SOME OF ITS BENEFICIAL EFFECTS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
10  629  37 DIFFERENCES IN BRAIN STRUCTURE AND FUNCTION AMONG YOGA PRACTITIONERS AND CONTROLS. BACKGROUND: YOGA IS A MIND-BODY BASED PHYSICAL ACTIVITY THAT HAS DEMONSTRATED A VARIETY OF PHYSIOLOGICAL, PSYCHOLOGICAL AND COGNITIVE HEALTH BENEFITS. ALTHOUGH YOGA PRACTICE HAS SHOWN TO IMPROVE COGNITIVE PERFORMANCE, FEW STUDIES HAVE EXAMINED THE UNDERLYING NEUROLOGICAL CORRELATES. OBJECTIVE: THE CURRENT STUDY AIMED TO DETERMINE THE DIFFERENCES IN GRAY MATTER VOLUME OF THE HIPPOCAMPUS, THALAMUS AND CAUDATE NUCLEUS AND BRAIN ACTIVATION DURING THE STERNBERG WORKING MEMORY TASK. METHOD: PARTICIPANTS WERE 13 EXPERIENCED YOGA PRACTITIONERS (MEAN AGE = 35.8), DEFINED AS HAVING MORE THAN 3 YEARS OF REGULAR YOGA PRACTICE, AND 13 AGE- AND SEX-MATCHED CONTROLS (MEAN AGE = 35.7). ALL PARTICIPANTS COMPLETED A 6-MIN WALK TEST TO ASSESS FITNESS, PSYCHOSOCIAL AND DEMOGRAPHIC QUESTIONNAIRES; AND UNDERWENT MAGNETIC RESONANCE IMAGING TO ASSESS GRAY MATTER VOLUME AND BRAIN ACTIVATION. RESULTS: THERE WERE NO GROUP DIFFERENCES ON DEMOGRAPHIC MEASURES OF INCOME, EDUCATION AND ON ESTIMATED VO2MAX OR PHYSICAL ACTIVITY LEVELS. GRAY MATTER VOLUME DIFFERENCES WERE OBSERVED IN THE LEFT HIPPOCAMPUS, SHOWING GREATER VOLUME IN EXPERIENCED YOGA PRACTITIONERS COMPARED TO CONTROLS (P = 0.017). THE FUNCTIONAL MRI RESULTS REVEALED LESS ACTIVATION IN THE DORSOLATERAL PREFRONTAL CORTEX IN YOGA PRACTITIONERS COMPARED TO CONTROLS DURING THE ENCODING PHASE OF THE STERNBERG TASK (P < 0.05). REACTION TIME AND ACCURACY ON THE TASK DID NOT DIFFER BETWEEN THE GROUPS. CONCLUSIONS: OUR RESULTS SUGGEST AN ASSOCIATION BETWEEN REGULAR LONG-TERM YOGA PRACTICE AND DIFFERENTIAL STRUCTURE AND FUNCTION OF SPECIFIC BRAIN REGIONS INVOLVED IN EXECUTIVE FUNCTION, SPECIFICALLY WORKING MEMORY, WHICH HAS PREVIOUSLY SHOWN TO IMPROVE WITH YOGA PRACTICE. FUTURE STUDIES NEED TO EXAMINE INTERVENTION EFFECTS OF YOGA AND EXPLORE ITS POTENTIAL TO MAINTAIN AND IMPROVE COGNITIVE HEALTH ACROSS THE LIFESPAN THROUGH LONGITUDINAL AND INTERVENTION STUDIES.	2018

RESULTS: RELATIVE TO BASELINE, AT THE BEGINNING OF THE MEDITATION SESSIONS THERE WAS A SIGNIFICANT INCREASE OF ACTIVATION IN BILATERAL INFERIOR FRONTAL AND TEMPORAL REGIONS. ACTIVATION BECAME PROGRESSIVELY MORE REDUCED WITH DEEPER MEDITATION STAGES AND IN THE LAST MEDITATION SESSION IT BECAME LOCALIZED TO THE RIGHT INFERIOR FRONTAL CORTEX/ RIGHT INSULA AND RIGHT MIDDLE/SUPERIOR TEMPORAL CORTEX. FURTHERMORE, RIGHT INFERIOR FRONTAL ACTIVATION WAS DIRECTLY ASSOCIATED WITH THE SUBJECTIVE DEPTH OF THE MENTAL SILENCE EXPERIENCE. CONCLUSIONS: MEDITATORS APPEAR TO PASS THROUGH AN INITIAL INTENSE NEURAL SELF-CONTROL PROCESS NECESSARY TO SILENCE THEIR MIND. AFTER THIS THEY EXPERIENCE RELATIVELY REDUCED BRAIN ACTIVATION CONCOMITANT WITH THE DEEPENING OF THE STATE OF MENTAL SILENCE OVER RIGHT INFERIOR FRONTAL CORTEX, PROBABLY REFLECTING AN EFFORTLESS PROCESS OF ATTENTIONAL CONTEMPLATION ASSOCIATED WITH THIS STATE.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
12 1098  33 EFFECTS OF YOGA RESPIRATORY PRACTICE (BHASTRIKA PRANAYAMA) ON ANXIETY, AFFECT, AND BRAIN FUNCTIONAL CONNECTIVITY AND ACTIVITY: A RANDOMIZED CONTROLLED TRIAL. PRANAYAMA REFERS TO A SET OF YOGA BREATHING EXERCISES. RECENT EVIDENCE SUGGESTS THAT THE PRACTICE OF PRANAYAMA HAS POSITIVE EFFECTS ON MEASURES OF CLINICAL STRESS AND ANXIETY. THIS STUDY EXPLORED THE IMPACT OF A BHASTRIKA PRANAYAMA TRAINING PROGRAM ON EMOTION PROCESSING, ANXIETY, AND AFFECT. WE USED A RANDOMIZED CONTROLLED TRIAL DESIGN WITH THIRTY HEALTHY YOUNG ADULTS ASSESSED AT BASELINE AND AFTER 4 WEEKS OF PRANAYAMA PRACTICES. TWO FUNCTIONAL MAGNETIC RESONANCE IMAGING (MRI) PROTOCOLS WERE USED BOTH AT BASELINE AND POST-INTERVENTION: AN EMOTION TASK AS WELL AS A RESTING-STATE ACQUISITION. OUR RESULTS SUGGEST THAT PRANAYAMA SIGNIFICANTLY DECREASED STATES OF ANXIETY AND NEGATIVE AFFECT. THE PRACTICE OF PRANAYAMA ALSO MODULATED THE ACTIVITY OF BRAIN REGIONS INVOLVED IN EMOTIONAL PROCESSING, PARTICULARLY THE AMYGDALA, ANTERIOR CINGULATE, ANTERIOR INSULA, AND PREFRONTAL CORTEX. RESTING-STATE FUNCTIONAL MRI (FMRI) SHOWED SIGNIFICANTLY REDUCED FUNCTIONAL CONNECTIVITY INVOLVING THE ANTERIOR INSULA AND LATERAL PORTIONS OF THE PREFRONTAL CORTEX. CORRELATION ANALYSIS REVEALED THAT CHANGES IN CONNECTIVITY BETWEEN THE VENTROLATERAL PREFRONTAL CORTEX AND THE RIGHT ANTERIOR INSULA WERE ASSOCIATED WITH CHANGES IN ANXIETY. ALTHOUGH IT SHOULD BE NOTED THAT THESE ANALYSES WERE PRELIMINARY AND EXPLORATORY, IT PROVIDES THE FIRST EVIDENCE THAT 4 WEEKS OF B. PRANAYAMA SIGNIFICANTLY REDUCE THE LEVELS OF ANXIETY AND NEGATIVE AFFECT, AND THAT THESE CHANGES ARE ASSOCIATED WITH THE MODULATION OF ACTIVITY AND CONNECTIVITY IN BRAIN AREAS INVOLVED IN EMOTION PROCESSING, ATTENTION, AND AWARENESS.

13 1668  29 NEUROCOGNITIVE CORRELATES OF THE EFFECTS OF YOGA MEDITATION PRACTICE ON EMOTION AND COGNITION: A PILOT STUDY. MINDFULNESS MEDITATION INVOLVES ATTENDING TO EMOTIONS WITHOUT COGNITIVE FIXATION OF EMOTIONAL EXPERIENCE. OVER TIME, THIS PRACTICE IS HELD TO PROMOTE ALTERATIONS IN TRAIT AFFECTIVITY AND ATTENTIONAL CONTROL WITH RESULTANT EFFECTS ON WELL-BEING AND COGNITION. HOWEVER, RELATIVELY LITTLE IS KNOWN REGARDING THE NEURAL SUBSTRATES OF MEDITATION EFFECTS ON EMOTION AND COGNITION. THE PRESENT STUDY INVESTIGATED THE NEUROCOGNITIVE CORRELATES OF EMOTION INTERFERENCE ON COGNITION IN YOGA PRACTITIONERS AND A MATCHED CONTROL GROUP (CG) UNDERWENT FMRI WHILE PERFORMING AN EVENT-RELATED AFFECTIVE STROOP TASK. THE TASK INCLUDES IMAGE VIEWING TRIALS AND STROOP TRIALS BRACKETED BY NEUTRAL OR NEGATIVE EMOTIONAL DISTRACTORS. DURING IMAGE VIEWING TRIALS, YOGA PRACTITIONERS EXHIBITED LESS REACTIVITY IN RIGHT DORSOLATERAL PREFRONTAL CORTEX (DLPFC) TO NEGATIVE AS COMPARED TO NEUTRAL IMAGES; WHEREAS THE CG HAD THE OPPOSITE PATTERN. A MAIN EFFECT OF VALENCE (NEGATIVE > NEUTRAL) WAS OBSERVED IN LIMBIC REGIONS (E.G., AMYGDALA), OF WHICH THE MAGNITUDE WAS INVERSELY RELATED TO DLPFC ACTIVATION. EXPLORATORY ANALYSES REVEALED THAT THE MAGNITUDE OF AMYGDALA ACTIVATION PREDICTED DECREASED SELF-REPORTED POSITIVE AFFECT IN THE CG, BUT NOT AMONG YOGA PRACTITIONERS. DURING STROOP TRIALS, YOGA PRACTITIONERS HAD GREATER ACTIVATION IN VENTROLATERAL PREFRONTAL CORTEX (VLPFC) DURING STROOP TRIALS WHEN NEGATIVE, COMPARED TO NEUTRAL, EMOTIONAL DISTRACTOR WERE PRESENTED; THE CG EXHIBITED THE OPPOSITE PATTERN. TAKEN TOGETHER, THESE DATA SUGGEST THAT THOUGH YOGA PRACTITIONERS EXHIBIT LIMBIC REACTIVITY TO NEGATIVE EMOTIONAL STIMULI, SUCH REACTIVITY DOES NOT HAVE DOWNSTREAM EFFECTS ON LATER MOOD STATE. THIS UNCOUPLING OF VIEWING NEGATIVE EMOTIONAL IMAGES AND AFFECT AMONG YOGA PRACTITIONERS MAY BE OCCASIONED BY THEIR SELECTIVE IMPLEMENTATION OF FRONTAL EXECUTIVE-DEPENDENT STRATEGIES TO REDUCE EMOTIONAL INTERFERENCE DURING COMPETING COGNITIVE DEMANDS AND NOT DURING EMOTIONAL PROCESSING PER SE.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
14  455  39 CHANGES IN NEURAL CONNECTIVITY AND MEMORY FOLLOWING A YOGA INTERVENTION FOR OLDER ADULTS: A PILOT STUDY. BACKGROUND: NO STUDY HAS EXPLORED THE EFFECT OF YOGA ON COGNITIVE DECLINE AND RESTING-STATE FUNCTIONAL CONNECTIVITY. OBJECTIVES: THIS STUDY EXPLORED THE RELATIONSHIP BETWEEN PERFORMANCE ON MEMORY TESTS AND RESTING-STATE FUNCTIONAL CONNECTIVITY BEFORE AND AFTER A YOGA INTERVENTION VERSUS ACTIVE CONTROL FOR SUBJECTS WITH MILD COGNITIVE IMPAIRMENT (MCI). METHODS: PARTICIPANTS ( >/= 55 Y) WITH MCI WERE RANDOMIZED TO RECEIVE A YOGA INTERVENTION OR ACTIVE "GOLD-STANDARD" CONTROL (I.E., MEMORY ENHANCEMENT TRAINING (MET)) FOR 12 WEEKS. RESTING-STATE FUNCTIONAL MAGNETIC RESONANCE IMAGING WAS USED TO MAP CORRELATIONS BETWEEN BRAIN NETWORKS AND MEMORY PERFORMANCE CHANGES OVER TIME. DEFAULT MODE NETWORKS (DMN), LANGUAGE AND SUPERIOR PARIETAL NETWORKS WERE CHOSEN AS NETWORKS OF INTEREST TO ANALYZE THE ASSOCIATION WITH CHANGES IN VERBAL AND VISUOSPATIAL MEMORY PERFORMANCE. RESULTS: FOURTEEN YOGA AND 11 MET PARTICIPANTS COMPLETED THE STUDY. THE YOGA GROUP DEMONSTRATED A STATISTICALLY SIGNIFICANT IMPROVEMENT IN DEPRESSION AND VISUOSPATIAL MEMORY. WE OBSERVED IMPROVED VERBAL MEMORY PERFORMANCE CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE DMN AND FRONTAL MEDIAL CORTEX, PREGENUAL ANTERIOR CINGULATE CORTEX, RIGHT MIDDLE FRONTAL CORTEX, POSTERIOR CINGULATE CORTEX, AND LEFT LATERAL OCCIPITAL CORTEX. IMPROVED VERBAL MEMORY PERFORMANCE POSITIVELY CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE LANGUAGE PROCESSING NETWORK AND THE LEFT INFERIOR FRONTAL GYRUS. IMPROVED VISUOSPATIAL MEMORY PERFORMANCE CORRELATED INVERSELY WITH CONNECTIVITY BETWEEN THE SUPERIOR PARIETAL NETWORK AND THE MEDIAL PARIETAL CORTEX. CONCLUSION: YOGA MAY BE AS EFFECTIVE AS MET IN IMPROVING FUNCTIONAL CONNECTIVITY IN RELATION TO VERBAL MEMORY PERFORMANCE.

OBJECTIVES: TO UNDERSTAND THE MEANING WOMEN WITH PAIN-ASSOCIATED ENDOMETRIOSIS ATTRIBUTE TO YOGA PRACTICE REGARDING THEIR PHYSICAL AND EMOTIONAL STATE AT THE BEGINNING OF THE PRACTICE; PAIN MANAGEMENT BY INTEGRATING BODY AND MIND; SECONDARY BENEFITS OF THE PRACTICE OF YOGA, SUCH AS SELF-KNOWLEDGE, SELF-CARE, AND AUTONOMY; AND THE ROLE OF THE YOGA GROUP AS PSYCHOSOCIAL SUPPORT. DESIGN: QUALITATIVE STUDY CONDUCTED SIMULTANEOUSLY WITH A RANDOMIZED CLINICAL TRIAL. SETTING: PUBLIC UNIVERSITY HOSPITAL IN SOUTHEASTERN BRAZIL BETWEEN AUGUST 2013 AND DECEMBER 2014. PARTICIPANTS: FIFTEEN WOMEN WITH PAIN-ASSOCIATED ENDOMETRIOSIS WHO PRACTICED YOGA FOR 8 WEEKS. INTERVENTION: AFTER COMPLETING THE TWICE-A-WEEK PROGRAM, ALL WOMEN PARTICIPATED IN A SINGLE, SEMI-STRUCTURED INTERVIEW. INTERVIEWS WERE RECORDED AND TRANSCRIBED VERBATIM, AND THEMATIC ANALYSES WERE PERFORMED. OUTCOME MEASURES: THE MAIN THEMES OF ANALYSIS WERE WOMEN'S EXPECTATIONS REGARDING THE PRACTICE OF YOGA, PHYSICAL AND EMOTIONAL STATE OF WOMEN AT THE BEGINNING OF YOGA PRACTICE, CONTROL AND PAIN MANAGEMENT THROUGH THE INTEGRATION OF BODY AND MIND, SECONDARY BENEFITS, ACQUISITION OF SELF-KNOWLEDGE AND AUTONOMY, AND THE ROLE OF YOGA GROUP AS PSYCHOSOCIAL SUPPORT. RESULTS: ALL PARTICIPANTS REPORTED THAT YOGA WAS BENEFICIAL TO CONTROL PELVIC PAIN. THEY RELATED THAT THEY WERE AWARE OF THE INTEGRATION OF BODY AND PSYCHE DURING YOGA PRACTICE AND THAT THIS HELPED IN THE MANAGEMENT OF PAIN. WOMEN SAID THEY HAD IDENTIFIED A RELATIONSHIP BETWEEN PAIN MANAGEMENT AND BREATHING TECHNIQUES (PRANAYAMA) LEARNED IN YOGA AND THAT BREATHING INCREASED THEIR ABILITY TO BE INTROSPECTIVE, WHICH RELIEVED PAIN. THE PARTICIPANTS HAVE DEVELOPED GREATER SELF-KNOWLEDGE, AUTONOMY, AND SELF-CARE AND HAVE REDUCED THE USE OF PAIN AND PSYCHIATRIC MEDICATIONS. THEY CREATED TIES AMONG THEMSELVES, SUGGESTING THAT THE YOGA GROUP ALLOWED PSYCHOSOCIAL SUPPORT. CONCLUSIONS: BODILY AND PSYCHOSOCIAL MECHANISMS TO CONTROL PAIN WERE IDENTIFIED IN WOMEN WITH ENDOMETRIOSIS. TO REACH SUCH CONTROL, IT IS CRUCIAL THAT MIND AND BODY INTEGRATIVE TECHNIQUES ARE LEARNED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16 1211  29 EXPLORING HOW DIFFERENT TYPES OF YOGA CHANGE PSYCHOLOGICAL RESOURCES AND EMOTIONAL WELL-BEING ACROSS A SINGLE SESSION. OBJECTIVES: YOGA DEMONSTRATES BENEFICIAL EFFECTS IN MANY POPULATIONS, YET OUR UNDERSTANDING OF HOW YOGA BRINGS ABOUT THESE EFFECTS IS QUITE LIMITED. AMONG THE PROPOSED MECHANISMS OF YOGA ARE INCREASING PSYCHOLOGICAL RESOURCES (MINDFULNESS, BODY CONSCIOUSNESS, SELF-TRANSCENDENCE, SPIRITUAL PEACE, AND SOCIAL CONNECTEDNESS) THAT MAY BRING ABOUT SALUTARY EFFECTS ON EMOTIONAL WELLBEING. FURTHER, YOGA IS A COMPLEX PRACTICE COMPRISING MEDITATION, ACTIVE AND RESTORATIVE POSTURES, AND BREATHWORK; HOWEVER LITTLE IS KNOWN ABOUT HOW DIFFERENT COMPONENTS MAY AFFECT MECHANISMS. WE AIMED TO DETERMINE HOW AN ACUTE SESSION OF YOGA (AND ITS SPECIFIC COMPONENTS) RELATED TO PRE- TO POST- SESSION CHANGES IN PROPOSED MECHANISMS (PSYCHOLOGICAL RESOURCES) AND WHETHER THOSE CHANGES WERE ASSOCIATED WITH POSITIVE CHANGES IN EMOTIONS. DESIGN: 144 REGULAR YOGA PRACTITIONERS COMPLETED MEASURES OF MINDFULNESS, BODY CONSCIOUSNESS, SELF-TRANSCENDENCE, SOCIAL CONNECTEDNESS, SPIRITUAL PEACE, AND EXERCISE-INDUCED EMOTIONS (POSITIVE ENGAGEMENT, REVITALIZATION, TRANQUILITY, EXHAUSTION) IMMEDIATELY BEFORE AND AFTER A YOGA SESSION (N=11 SESSIONS, EACH A DIFFERENT TYPE OF YOGA). PERCEIVED PROPERTIES OF EACH YOGA SESSION, EXERCISE EXERTION AND ENGAGEMENT WITH THE YOGA TEACHER WERE ASSESSED IMMEDIATELY FOLLOWING THE SESSION. RESULTS: PRE-TO POST- YOGA, LEVELS OF POSITIVE EMOTIONS (ENGAGEMENT, TRANQUILITY AND REVITALIZATION) INCREASED WHILE EXHAUSTION DECREASED. FURTHER, ALL PSYCHOLOGICAL RESOURCES INCREASED AND CLOSELY TRACKED IMPROVED EMOTIONS. ADDITIONALLY, ASPECTS OF THE YOGA SESSION CORRELATED WITH CHANGES IN PSYCHOLOGICAL RESOURCES (MECHANISMS) AND EMOTIONS. CONCLUSIONS: YOGA MAY INFLUENCE MULTIPLE PSYCHOLOGICAL MECHANISMS THAT INFLUENCE EMOTIONAL WELL-BEING. FURTHER, DIFFERENT TYPES OF YOGA MAY AFFECT DIFFERENT MECHANISMS. RESULTS CAN INFORM YOGA INTERVENTIONS AIMING TO OPTIMIZE EFFECTS THROUGH SPECIFIC MECHANISMS SUCH AS MINDFULNESS OR SPIRITUALITY.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
17  888  39 EFFECT OF YOGA VERSUS LIGHT EXERCISE TO IMPROVE WELL-BEING AND PROMOTE HEALTHY AGING AMONG OLDER ADULTS IN CENTRAL INDIA: A STUDY PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: AGING IS A NATURAL PROCESS ASSOCIATED WITH MANY FUNCTIONAL AND STRUCTURAL CHANGES. THESE CHANGES MAY INCLUDE IMPAIRED SELF-REGULATION, CHANGES IN TISSUES AND ORGANS. AGING ALSO AFFECTS MOOD, PHYSICAL STATUS AND SOCIAL ACTIVITY. THERE ARE ADVERSE CHANGES IN COGNITIVE BEHAVIOR, PERCEIVED SENSATION AND THINKING PROCESSES. REGULAR PHYSICAL ACTIVITY CAN ALLEVIATE MANY HEALTH PROBLEMS; YET, MANY OLDER ADULTS ARE INACTIVE. YOGA IS ONE OF THE SCIENTIFIC AND POPULAR LIFESTYLE PRACTICE CONSIDERED AS THE INTEGRATION OF MIND, BODY AND SOUL. RESULTS OF PREVIOUS STUDIES REPORTED POSITIVE EFFECTS OF YOGA ON MULTIPLE HEALTH OUTCOMES IN ELDERLY. HOWEVER, THERE IS SCARCITY OF SCIENTIFIC INFORMATION WHERE YOGA'S EFFECT IS EXAMINED ON OVER WELL-BEING AND ON MULTIPLE HEALTH OUTCOMES SIMULTANEOUSLY IN ELDERLY. THIS PROTOCOL DESCRIBES METHODS FOR A 12-WEEK YOGA-BASED INTERVENTION EXPLORING THE EFFECTS OF YOGA ON WELL-BEING IN PHYSICALLY INACTIVE ELDERLY LIVING IN COMMUNITY. METHODS AND ANALYSIS: THIS TWO GROUP PARALLEL SINGLE BLIND RANDOMIZED CONTROLLED TRIAL THAT WILL BE CONDUCTED AT A DESIGNATED FACILITY OF R.D. GARDI MEDICAL COLLEGE, UJJAIN, MADHYA PRADESH, CENTRAL INDIA. A 12-WEEK 60-MIN YOGA INTERVENTION THREE TIMES WEEKLY IS DESIGNED. COMPARISON GROUP PARTICIPANTS WILL UNDERGO A 60-MIN PROGRAM COMPRISING LIGHT EXERCISE FOCUSING ON CONVENTIONAL STRETCHING TO IMPROVE MOBILITY. AFTER SCREENING, 144 PARTICIPANTS AGED 60-80 YEARS WILL BE RECRUITED. THE PRIMARY OUTCOME IS SUBJECTIVE WELL-BEING. SECONDARY OUTCOMES INCLUDE MOBILITY, FALL RISK, COGNITION, ANXIETY AND DEPRESSION, MOOD AND STRESS, SLEEP QUALITY, PAIN, PHYSICAL ACTIVITY/SEDENTARY BEHAVIOR AND CARDIO-METABOLIC RISK FACTORS. ASSESSMENTS WILL BE CONDUCTED AT BASELINE (0 WEEK), AFTER THE INTERVENTION (12+1 WEEK) AND AT FOLLOW-UP (36+1 WEEK). INTENTION-TO-TREAT ANALYSES WITH MIXED LINEAR MODELING WILL BE APPLIED. DISCUSSION: THROUGH THIS TRIAL, WE AIM TO DETERMINE WHETHER ELDERLY PEOPLE IN THE INTERVENTION GROUP PRACTICING YOGA SHOW MORE FAVORABLE PRIMARY (WELL-BEING) AND SECONDARY OUTCOMES THAN THOSE IN THE LIGHT EXERCISE FOCUSING ON CONVENTIONAL STRETCHING GROUP. WE ASSUME THAT YOGA MAY BE PRACTICED TO MAINTAIN HEALTH, REDUCE PARTICULAR SYMPTOMS COMMONLY ASSOCIATED WITH SKELETAL PAIN, ASSIST IN PAIN RELIEF AND ENHANCE WELL-BEING. WE ANTICIPATE THAT PRACTICING YOGA WILL IMPROVE WELL-BEING AND MENTAL HEALTH AND MAY LEAD TO SIGNIFICANT IMPROVEMENT IN DEPRESSION, PAIN AND SLEEP QUALITY.ETHICS AND DISSEMINATION: THIS STUDY IS APPROVED BY THE INSTITUTIONAL ETHICS COMMITTEE OF R.D. GARDI MEDICAL COLLEGE, UJJAIN, IEC REF NO. 09/2018. ALL PARTICIPANTS WOULD BE PROVIDED WITH WRITTEN AND VERBAL INFORMATION ABOUT THE PURPOSE OF THE PROJECT AND WOULD BE FREE TO WITHDRAW FROM THE STUDY AT ANY TIME. REFUSAL TO PARTICIPATE IN THE STUDY WOULD NOT HAVE ANY NEGATIVE CONSEQUENCES. CONFIDENTIALITY OF THE INFORMATION OF EACH PARTICIPANT WOULD BE ENSURED. KNOWLEDGE OBTAINED WOULD BE DISSEMINATED TO STAKEHOLDERS THROUGH WORKSHOPS, MEETINGS AND RELEVANT SCIENTIFIC CONFERENCES. TRIAL REGISTRATION: THE TRIAL IS PROSPECTIVELY REGISTERED WITH THE INDIAN COUNCIL OF MEDICAL RESEARCH TRIAL REGISTRY CTRI/2018/07/015051.	2019	

18 1266  18 FLUID INTELLIGENCE AND BRAIN FUNCTIONAL ORGANIZATION IN AGING YOGA AND MEDITATION PRACTITIONERS. NUMEROUS STUDIES HAVE DOCUMENTED THE NORMAL AGE-RELATED DECLINE OF NEURAL STRUCTURE, FUNCTION, AND COGNITIVE PERFORMANCE. PRELIMINARY EVIDENCE SUGGESTS THAT MEDITATION MAY REDUCE DECLINE IN SPECIFIC COGNITIVE DOMAINS AND IN BRAIN STRUCTURE. HERE WE EXTENDED THIS RESEARCH BY INVESTIGATING THE RELATION BETWEEN AGE AND FLUID INTELLIGENCE AND RESTING STATE BRAIN FUNCTIONAL NETWORK ARCHITECTURE USING GRAPH THEORY, IN MIDDLE-AGED YOGA AND MEDITATION PRACTITIONERS, AND MATCHED CONTROLS. FLUID INTELLIGENCE DECLINED SLOWER IN YOGA PRACTITIONERS AND MEDITATORS COMBINED THAN IN CONTROLS. RESTING STATE FUNCTIONAL NETWORKS OF YOGA PRACTITIONERS AND MEDITATORS COMBINED WERE MORE INTEGRATED AND MORE RESILIENT TO DAMAGE THAN THOSE OF CONTROLS. FURTHERMORE, MINDFULNESS WAS POSITIVELY CORRELATED WITH FLUID INTELLIGENCE, RESILIENCE, AND GLOBAL NETWORK EFFICIENCY. THESE FINDINGS REVEAL THE POSSIBILITY TO INCREASE RESILIENCE AND TO SLOW THE DECLINE OF FLUID INTELLIGENCE AND BRAIN FUNCTIONAL ARCHITECTURE AND SUGGEST THAT MINDFULNESS PLAYS A MECHANISTIC ROLE IN THIS PRESERVATION.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
19 1698  17 PAIN-RELATED ENCEPHALIC REGIONS INFLUENCED BY YOGA MEDITATION: AN INTEGRATIVE REVIEW. INTRODUCTION: THE MECHANISMS UNDERLYING THE USE OF YOGA IN PAIN RELIEF ARE STILL UNCLEAR. THIS STUDY REVIEWED LITERATURE REPORTS ON ENCEPHALIC ACTIVITY RELATED TO ANALGESIA INDUCED BY YOGA MEDITATION PRACTICE. METHODS: THIS INTEGRATIVE REVIEW EXAMINED STUDIES PUBLISHED IN THE PUBMED, LILACS AND MEDLINE DATABASES WITHOUT RESTRICTION OF THE YEAR OF PUBLICATION. THE RESEARCH INVOLVED 16 DESCRIPTORS RELATED TO THE WORDS: YOGA, PAIN AND NEUROIMAGING METHODS. INCLUSION CRITERIA INVOLVED ONLY THE PUBLICATIONS AVAILABLE ONLINE, WITH FREE ACCESS AND WRITTEN IN ENGLISH. RESULTS: 2 CASE STUDIES AND 1 PILOT STUDY MET THE CRITERIA. YOGA MEDITATION PRACTICE INDUCES ANALGESIA PRIMARILY THROUGH ATTENUATION OF THE MEDIAL PAIN PERCEPTION SYSTEM INCLUDING THE ANTERIOR CINGULATE CORTEX AND INSULA REGIONS, AS WELL AS THE LATERAL SYSTEM INCLUDING THE SECONDARY SENSORY CORTEX AND THALAMUS. CONCLUSION: YOGA INDUCED ANALGESIA IS A POTENTIALLY IMPORTANT ADJUNCT TO CURRENT PAIN MANAGEMENT. THIS INTEGRATIVE REVIEW REVEALED THAT THERE IS A NEED FOR FURTHER RESEARCH THAT ANALYZES THE ENCEPHALIC REGIONS RELATED TO ANALGESIA INDUCED BY YOGA PRACTICE.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20 1286  30 GRAY MATTER AND FUNCTIONAL CONNECTIVITY IN ANTERIOR CINGULATE CORTEX ARE ASSOCIATED WITH THE STATE OF MENTAL SILENCE DURING SAHAJA YOGA MEDITATION. SOME MEDITATION TECHNIQUES TEACH THE PRACTITIONER TO ACHIEVE THE STATE OF MENTAL SILENCE. THE AIM OF THIS STUDY WAS TO INVESTIGATE BRAIN REGIONS THAT ARE ASSOCIATED WITH THEIR VOLUME AND FUNCTIONAL CONNECTIVITY (FC) WITH THE DEPTH OF MENTAL SILENCE IN LONG-TERM PRACTITIONERS OF SAHAJA YOGA MEDITATION. TWENTY-THREE LONG-TERM PRACTITIONERS OF THIS MEDITATION WERE SCANNED USING MAGNETIC RESONANCE IMAGING. IN ORDER TO IDENTIFY THE NEURAL CORRELATES OF THE DEPTH OF MENTAL SILENCE, WE TESTED WHICH GRAY MATTER VOLUMES (GMV) WERE CORRELATED WITH THE DEPTH OF MENTAL SILENCE AND WHICH REGIONS THESE AREAS WERE FUNCTIONALLY CONNECTED TO UNDER A MEDITATION CONDITION. GMV IN MEDIAL PREFRONTAL CORTEX INCLUDING ROSTRAL ANTERIOR CINGULATE CORTEX WERE POSITIVELY CORRELATED WITH THE SUBJECTIVE PERCEPTION OF THE DEPTH OF MENTAL SILENCE INSIDE THE SCANNER. FURTHERMORE, THERE WAS SIGNIFICANTLY INCREASED FC BETWEEN THIS AREA AND BILATERAL ANTERIOR INSULA/PUTAMEN DURING A MEDITATION-STATE SPECIFICALLY, WHILE DECREASED CONNECTIVITY WITH THE RIGHT THALAMUS/PARAHIPPOCAMPAL GYRUS WAS PRESENT DURING THE MEDITATION-STATE AND THE RESTING-STATE. THE CAPACITY OF LONG-TERM MEDITATORS TO ESTABLISH A DURABLE STATE OF MENTAL SILENCE INSIDE AN MRI SCANNER WAS ASSOCIATED WITH LARGER GRAY MATTER VOLUME IN A MEDIAL FRONTAL REGION THAT IS CRUCIAL FOR TOP-DOWN COGNITIVE, EMOTION AND ATTENTION CONTROL. THIS IS FURTHERMORE CORROBORATED BY INCREASED FC OF THIS REGION DURING THE MEDITATION-STATE WITH BILATERAL ANTERIOR INSULA/PUTAMEN, WHICH ARE IMPORTANT FOR INTEROCEPTION, EMOTION, AND ATTENTION REGULATION. THE FINDINGS HENCE SUGGEST THAT THE DEPTH OF MENTAL SILENCE IS ASSOCIATED WITH MEDIAL FRONTO-INSULAR-STRIATAL NETWORKS THAT ARE CRUCIAL FOR TOP-DOWN ATTENTION AND EMOTIONAL CONTROL.	2018
