1 1089 133 EFFECTS OF YOGA ON THE AUTONOMIC NERVOUS SYSTEM, GAMMA-AMINOBUTYRIC-ACID, AND ALLOSTASIS IN EPILEPSY, DEPRESSION, AND POST-TRAUMATIC STRESS DISORDER. A THEORY IS PROPOSED TO EXPLAIN THE BENEFITS OF YOGA PRACTICES IN DIVERSE, FREQUENTLY COMORBID MEDICAL CONDITIONS BASED ON THE CONCEPT THAT YOGA PRACTICES REDUCE ALLOSTATIC LOAD IN STRESS RESPONSE SYSTEMS SUCH THAT OPTIMAL HOMEOSTASIS IS RESTORED. IT IS HYPOTHESIZED THAT STRESS INDUCES (1) IMBALANCE OF THE AUTONOMIC NERVOUS SYSTEM (ANS) WITH DECREASED PARASYMPATHETIC NERVOUS SYSTEM (PNS) AND INCREASED SYMPATHETIC NERVOUS SYSTEM (SNS) ACTIVITY, (2) UNDERACTIVITY OF THE GAMMA AMINO-BUTYRIC ACID (GABA) SYSTEM, THE PRIMARY INHIBITORY NEUROTRANSMITTER SYSTEM, AND (3) INCREASED ALLOSTATIC LOAD. IT IS FURTHER HYPOTHESIZED THAT YOGA-BASED PRACTICES (4) CORRECT UNDERACTIVITY OF THE PNS AND GABA SYSTEMS IN PART THROUGH STIMULATION OF THE VAGUS NERVES, THE MAIN PERIPHERAL PATHWAY OF THE PNS, AND (5) REDUCE ALLOSTATIC LOAD. DEPRESSION, EPILEPSY, POST TRAUMATIC STRESS DISORDER (PTSD), AND CHRONIC PAIN EXEMPLIFY MEDICAL CONDITIONS THAT ARE EXACERBATED BY STRESS, HAVE LOW HEART RATE VARIABILITY (HRV) AND LOW GABAERGIC ACTIVITY, RESPOND TO PHARMACOLOGIC AGENTS THAT INCREASE ACTIVITY OF THE GABA SYSTEM, AND SHOW SYMPTOM IMPROVEMENT IN RESPONSE TO YOGA-BASED INTERVENTIONS. THE OBSERVATION THAT TREATMENT RESISTANT CASES OF EPILEPSY AND DEPRESSION RESPOND TO VAGAL NERVE STIMULATION CORROBORATES THE NEED TO CORRECT PNS UNDERACTIVITY AS PART OF A SUCCESSFUL TREATMENT PLAN IN SOME CASES. ACCORDING TO THE PROPOSED THEORY, THE DECREASED PNS AND GABAERGIC ACTIVITY THAT UNDERLIES STRESS-RELATED DISORDERS CAN BE CORRECTED BY YOGA PRACTICES RESULTING IN AMELIORATION OF DISEASE SYMPTOMS. THIS HAS FAR-REACHING IMPLICATIONS FOR THE INTEGRATION OF YOGA-BASED PRACTICES IN THE TREATMENT OF A BROAD ARRAY OF DISORDERS EXACERBATED BY STRESS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                            
2 1881  18 REDUCED HYPOXIC VENTILATORY RESPONSE WITH PRESERVED BLOOD OXYGENATION IN YOGA TRAINEES AND HIMALAYAN BUDDHIST MONKS AT ALTITUDE: EVIDENCE OF A DIFFERENT ADAPTIVE STRATEGY? YOGA INDUCES LONG-TERM CHANGES IN RESPIRATORY FUNCTION AND CONTROL. WE TESTED WHETHER IT REPRESENTS A SUCCESSFUL STRATEGY FOR HIGH-ALTITUDE ADAPTATION. WE COMPARED VENTILATORY, CARDIOVASCULAR AND HEMATOLOGICAL PARAMETERS IN: 12 CAUCASIAN YOGA TRAINEES AND 12 CONTROL SEA-LEVEL RESIDENTS, AT BASELINE AND AFTER 2-WEEK EXPOSURE TO HIGH ALTITUDE (PYRAMID LABORATORY, NEPAL, 5,050 M), 38 ACTIVE LIFESTYLE HIGH-ALTITUDE NATIVES (SHERPAS) AND 13 CONTEMPLATIVE LIFESTYLE HIGH-ALTITUDE NATIVES WITH PRACTICE OF YOGA-LIKE RESPIRATORY EXERCISES (BUDDHIST MONKS) STUDIED AT 5,050 M. AT BASELINE, HYPOXIC VENTILATORY RESPONSE (HVR), RED BLOOD CELL COUNT AND HEMATOCRIT WERE LOWER IN CAUCASIAN YOGA TRAINEES THAN IN CONTROLS. AFTER 14 DAYS AT ALTITUDE, YOGA TRAINEES SHOWED SIMILAR OXYGEN SATURATION, BLOOD PRESSURE, RR INTERVAL COMPARED TO CONTROLS, BUT LOWER HVR (-0.44 +/- 0.08 VS. -0.98 +/- 0.21 L/MIN/M/%SAO(2), P < 0.05), MINUTE VENTILATION (8.3 +/- 0.9 VS. 10.8 +/- 1.6 L/MIN, P < 0.05), BREATHING RATE (INDICATING HIGHER VENTILATORY EFFICIENCY), AND LOWER RED BLOOD CELL COUNT, HEMOGLOBIN, HEMATOCRIT, ALBUMIN, ERYTHROPOIETIN AND SOLUBLE TRANSFERRIN RECEPTORS. HYPOXIC VENTILATORY RESPONSE IN MONKS WAS LOWER THAN IN SHERPAS (-0.23 +/- 0.05 VS. -0.63 +/- 0.09 L/MIN/M/%SAO(2), P < 0.05); VALUES WERE SIMILAR TO BASELINE DATA OF YOGA TRAINEES AND CAUCASIAN CONTROLS, RESPECTIVELY. RED BLOOD CELL COUNT AND HEMATOCRIT WERE LOWER IN MONKS AS COMPARED TO SHERPAS. IN CONCLUSION, CAUCASIAN SUBJECTS PRACTICING YOGA MAINTAIN A SATISFACTORY OXYGEN TRANSPORT AT HIGH ALTITUDE, WITH MINIMAL INCREASE IN VENTILATION AND WITH REDUCED HEMATOLOGICAL CHANGES, RESEMBLING HIMALAYAN NATIVES. RESPIRATORY ADAPTATIONS INDUCED BY THE PRACTICE OF YOGA MAY REPRESENT AN EFFICIENT STRATEGY TO COPE WITH ALTITUDE-INDUCED HYPOXIA.	2007	
                                                                                                                                                                                                                                                                                                                  
3  350  34 ASSESSMENT OF CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA IN ART OF LIVING PRACTITIONERS. OBJECTIVE: THE BREATHING PROCESSES ARE KNOWN TO MODULATE CARDIAC AUTONOMIC TONE AND IMPROVE PSYCHOLOGICAL STATUS. WE INVESTIGATED CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA (SKY) USING HEART RATE VARIABILITY (HRV) AND SKIN CONDUCTANCE LEVEL (SCL). METHODS: THIRTY HEALTHY VOLUNTEERS (AGE 28.3 +/- 8.4 YEARS; 23 M: 7 F) PARTICIPATED IN THE STUDY. ELECTROCARDIOGRAM (ECG) AND SCL WERE RECORDED FOR 5 MIN EACH, BEFORE AND AFTER LONG SKY. LONG SKY IS A COMBINATION OF PRANAYAMA AND CYCLIC RHYTHMIC BREATHING AND IS PERFORMED BY FOLLOWING THE GUIDED AUDIO INSTRUCTIONS. HRV ANALYSIS WAS USED FOR THE ASSESSMENT OF CARDIAC AUTONOMIC TONE. TIME AND FREQUENCY DOMAIN PARAMETERS OF HRV WERE CALCULATED BY USING RR INTERVAL OF ECG. SCL WAS ACQUIRED USING GALVANIC SKIN RESPONSE (GSR) AMPLIFIER OF POWERLAB IN MICROSEIMENS (MUS). RESULTS: TIME DOMAIN PARAMETERS OF HRV, INCLUDING MEAN RR INTERVAL (P = 0.000), RESPIRATORY SINUS ARRHYTHMIA (RSA) (P = 0.037), STANDARD DEVIATION OF ALL NN INTERVALS (SDNN) (P = 0.013), NN50 COUNT DIVIDED BY THE TOTAL NUMBER OF ALL NN INTERVALS (PNN50) (P = 0.004), AND SQUARE ROOT OF THE MEAN OF THE SUM OF THE SQUARES OF DIFFERENCES BETWEEN ADJACENT NN INTERVALS (RMSSD) (P = 0.002) INCREASED, AND MEAN HEART RATE DECREASED (P = 0.000) FOLLOWING LONG SKY. IN FREQUENCY DOMAIN ANALYSIS, POWER OF LOW-FREQUENCY (LF) COMPONENT (P = 0.010) AND LF/HF RATIO (P = 0.008) DECREASED SIGNIFICANTLY, WHEREAS POWER OF HIGH FREQUENCY (HF) SIGNIFICANTLY INCREASED (P = 0.010). SCL DECREASED FOLLOWING LONG SKY, ALTHOUGH IT DID NOT ATTAIN STATISTICAL SIGNIFICANCE. CONCLUSIONS: THE RESULTS SUGGEST THAT LONG SKY INDUCES SIGNIFICANT OSCILLATIONS IN CARDIAC AUTONOMIC TONE. PARASYMPATHETIC ACTIVITY INCREASES AND SYMPATHETIC ACTIVITY DECREASES AND SYMPATHOVAGAL BALANCE IMPROVES FOLLOWING LONG SKY. DECREASE IN SYMPATHETIC ACTIVITY IS ALSO DEMONSTRATED BY DECREASE IN CONDUCTANCE ALTHOUGH IT DID NOT REACH STATISTICAL SIGNIFICANCE. FROM THIS STUDY IT CAN BE CONCLUDED THAT LONG SKY HAS A BENEFICIAL EFFECT ON CARDIAC AUTONOMIC TONE, AND PSYCHOPHYSIOLOGICAL RELAXATION. IT MAY SERVE AS A TOOL TO IMPROVE HRV, WHICH IS THE MARKER OF CARDIOVASCULAR HEALTH.	2017	

4  369  18 AUTONOMIC FUNCTIONS IN RAJA-YOGA MEDITATORS. STRESS, AN INEVITABLE AND CONSTANT FEATURE THROUGHOUT THE LIFETIME, INDUCES AUTONOMIC DYSFUNCTIONS, FOR WHICH MEDITATION IS CONSIDERED TO BE AN ANTIDOTE. SO THE CASE CONTROL STUDY WAS PLANNED INCLUDING 50 RAJA-YOGA MEDITATORS PRACTICING MEDITATION FOR 5 YEARS AND 50 AGE MATCHED NON-MEDITATORS. AUTONOMIC FUNCTION TESTS WERE PERFORMED AND RESULTS WERE COMPARED USING THE STUDENT-T TEST. MEAN VALUES OF RESTING HR, SBP AND DBP WERE LESS IN MEDITATORS. GALVANIC SKIN RESPONSE IN MEDITATORS WAS SIGNIFICANTLY MORE (P < 0.001). MEAN INCREASE BP RESPONSE TO HAND GRIP TEST AND COLD PRESSOR TEST WAS SIGNIFICANTLY LESS IN MEDITATORS THAN NON-MEDITATORS (P < 0.001). STANDING: LYING RATIO, VALSALVA RATIO, INSPIRATION: EXPIRATION RATIO AND 30:15 RATIOS WERE SIGNIFICANTLY INCREASED IN MEDITATORS THAN NON-MEDITATORS. FROM THE RESULTS, THERE WAS SHIFTING OF THE AUTONOMIC BALANCE TO PARASYMPATHETIC SIDE IN RAJA-YOGA MEDITATORS, WHICH SUGGESTS ITS UTILITY TO COMBAT THE ILL EFFECTS OF STRESS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5   82  38 A MECHANISTIC MODEL FOR YOGA AS A PREVENTIVE AND THERAPEUTIC MODALITY. YOGA IS AN ANCIENT INDIAN TECHNIQUE OF HEALTHY LIVING. NUMEROUS STUDIES HAVE CORROBORATED YOGA'S BENEFICIAL EFFECTS, INCLUDING A FAVORABLE INFLUENCE ON AUTONOMIC FUNCTION AND NEGATIVE EMOTIONS. EXTENSIVE RESEARCH IN THE LAST FEW DECADES HAS REVEALED THE CRITICAL ROLE THAT YOGA CAN PLAY IN ERADICATING STRESS. THIS HAS LAID TO THE FOUNDATION FOR A SCIENTIFIC UNDERSTANDING OF PATHOPHYSIOLOGICAL CHANGES ATTRIBUTED TO STRESS, PARTICULARLY AT THE MOLECULAR AND GENETIC LEVELS. THIS PRIMARILY HAS HELPED UNDERSTAND THE EPIGENETIC AND GENETIC MECHANISM AT PLAY TO INDUCE AND ALLEVIATE STRESS, PARTICULARLY THOSE RELATED TO EMOTIONAL ABERRATIONS. AS RESEARCH HAS INDICATED, NEGATIVE EMOTIONS ARE TRANSLATED INTO VASCULAR INFLAMMATION APPROPRIATELY ACCENTUATED BY A SYMPATHETIC PREDOMINANT AUTONOMIC FUNCTION. THIS CASCADE IS BOLSTERED BY MULTIPLE FACTORS, INCLUDING ACTIVATION OF "STRESSOR" GENES AND ELABORATING HORMONES, INCLUDING STEROIDS WITH SOMETIMES NOCUOUS CONSEQUENCES, PARTICULARLY WHEN CHRONIC. YOGA HAS BEEN CATEGORICALLY FOUND TO HAVE INHIBITED EACH AND EVERY ONE OF THESE BANEFUL EFFECTS OF STRESS. IN FACT, IT ALSO CHANGES THE NEURONAL CIRCUITS THAT POTENTIATE SUCH A PLETHORA OF PATHOLOGICAL CHANGES. THIS, IN TURN, HAS ACCENTUATED YOGA'S RELEVANCE AS A POWERFUL PREVENTIVE INTERVENTION IN NONCOMMUNICABLE DISEASES (NCD). NCDS, INCLUDING HEART DISEASE, STROKE, AND RHEUMATOLOGICAL DISORDERS, ARE ESSENTIALLY INFLAMMATORY DISEASES THAT PERPETUATE INFLAMMATION IN DIFFERENT BEDS LIKE VASCULAR OR JOINT SPACES. THE PRECISE MECHANISM BY WHICH YOGA INDUCES SUCH BENEFICIAL CHANGES IS YET TO BE DELINEATED. HOWEVER, A CORNUCOPIA OF POINTERS INDICATES THAT NEURAL, ENDOCRINE, IMMUNOLOGICAL, CELLULAR, GENETIC, AND EPIGENETIC MECHANISMS ARE AT PLAY. THIS ARTICLE ATTEMPTS TO COBBLE TOGETHER NEWFANGLED RESEARCH TO DELINEATE A MEDICAL MODEL FOR THIS 5000-YEAR-OLD PRACTICE FROM INDIA. THIS IS IMPERATIVE, AS A MECHANISTIC MODEL OF THIS ANCIENT-BUT-COMPLEX SYSTEM WOULD ENABLE A MORE COMPREHENSIVE UNDERSTANDING OF ITS MECHANISM AND REVEAL ITS YET-UNDISCOVERED POSITIVE HEALTH EFFECTS.	2021	
                                                                                                                          
6 1610  19 METABOLIC AND VENTILATORY CHANGES DURING AND AFTER HIGH-FREQUENCY YOGA BREATHING. BACKGROUND PRACTICING HIGH-FREQUENCY YOGA BREATHING (HFYB) INDUCED A HYPERMETABOLIC STATE IN A SINGLE SUBJECT DURING THE PRACTICE BUT THE EFFECT HAS NOT BEEN STUDIED IN MULTIPLE PRACTITIONERS. MATERIAL AND METHODS HEALTHY MALE VOLUNTEERS (N=47, GROUP MEAN AGE +/- S.D., 23.2 +/- 4.1 YEARS) WERE RECRUITED AS AN EXPERIMENTAL GROUP AND ANOTHER TWENTY VOLUNTEERS WERE RECRUITED AS A CONTROL GROUP. THE EXPERIMENTAL GROUP PRACTICED EITHER HFYB (BREATH RATE 1.0 HZ) OR BREATH AWARENESS (BAW) ON TWO SEPARATE DAYS. THE SEQUENCE WAS REVERSED FOR ALTERNATE PARTICIPANTS. THE CONTROL GROUP WAS ASSESSED UNDER SIMILAR CONDITIONS WHILE SITTING AT EASE. THE BREATH RATE (RR), TIDAL VOLUME (VT), VENTILATION (VE), VO2, VCO2, ARTERIAL PCO2 AND ENERGY EXPENDITURE (EE KCAL/DAY) WERE ASSESSED FOR 35 MINUTES USING AN OPEN CIRCUIT OXYGEN CONSUMPTION ANALYZER. THE ASSESSMENT PERIOD WAS DIVIDED INTO BEFORE, DURING AND AFTER CONDITIONS. REPEATED MEASURES ANALYSES OF VARIANCE (ANOVA) WERE USED TO COMPARE DATA RECORDED DURING AND AFTER THE TWO PRACTICES WITH DATA RECORDED BEFORE. BEFORE-AFTER COMPARISONS IN THE CONTROL GROUP WERE WITH PAIRED T-TESTS. RESULTS THE MOST RELEVANT SIGNIFICANT CHANGES WERE INCREASES IN VE, VO2, VCO2 AND EE DURING HFYB, WHILE THE SAME VARIABLES DECREASED DURING THE CONTROL PERIOD. HOWEVER AFTER HFYB THERE WAS NO CHANGE IN VO2 OR EE, ALTHOUGH VE DECREASED AS IT DID AFTER THE CONTROL PERIOD. CONCLUSIONS HFYB INDUCES A HYPERMETABOLIC STATE FOR THE DURATION OF THE PRACTICE WHICH RETURNS TO BASELINE AFTER HFYB SUGGESTING A POSSIBLE APPLICATION FOR HFYB IN HYPOMETABOLIC STATES.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
7 1667  26 NEUROCHEMICAL AND NEUROANATOMICAL PLASTICITY FOLLOWING MEMORY TRAINING AND YOGA INTERVENTIONS IN OLDER ADULTS WITH MILD COGNITIVE IMPAIRMENT. BEHAVIORAL INTERVENTIONS ARE BECOMING INCREASINGLY POPULAR APPROACHES TO AMELIORATE AGE-RELATED COGNITIVE DECLINE, BUT THEIR UNDERLYING NEUROBIOLOGICAL MECHANISMS AND CLINICAL EFFICIENCY HAVE NOT BEEN FULLY ELUCIDATED. THE PRESENT STUDY EXPLORED BRAIN PLASTICITY ASSOCIATED WITH TWO BEHAVIORAL INTERVENTIONS, MEMORY ENHANCEMENT TRAINING (MET) AND A MIND-BODY PRACTICE (YOGIC MEDITATION), IN HEALTHY SENIORS WITH MILD COGNITIVE IMPAIRMENT (MCI) USING STRUCTURAL MAGNETIC RESONANCE IMAGING (S-MRI) AND PROTON MAGNETIC RESONANCE SPECTROSCOPY ((1)H-MRS). SENIOR PARTICIPANTS (AGE >/=55 YEARS) WITH MCI WERE RANDOMIZED TO THE MET OR YOGIC MEDITATION INTERVENTIONS. FOR BOTH INTERVENTIONS, PARTICIPANTS COMPLETED EITHER MET TRAINING OR KUNDALINI YOGA (KY) FOR 60-MIN SESSIONS OVER 12 WEEKS, WITH 12-MIN DAILY HOMEWORK ASSIGNMENTS. GRAY MATTER VOLUME AND METABOLITE CONCENTRATIONS IN THE DORSAL ANTERIOR CINGULATE CORTEX (DACC) AND BILATERAL HIPPOCAMPUS WERE MEASURED BY STRUCTURAL MRI AND (1)H-MRS AT BASELINE AND AFTER 12 WEEKS OF TRAINING. METABOLITES MEASURED INCLUDED GLUTAMATE-GLUTAMINE (GLX), CHOLINE-CONTAINING COMPOUNDS (CHO, INCLUDING GLYCEROPHOSPHOCHOLINE AND PHOSPHOCHOLINE), GAMMA-AMINOBUTYRIC ACID (GABA), AND N-ACETYL ASPARTATE AND N-ACETYLASPARTYL-GLUTAMATE (NAA-NAAG). IN TOTAL, 11 PARTICIPANTS COMPLETED MET AND 14 COMPLETED YOGIC MEDITATION FOR THIS STUDY. STRUCTURAL MRI ANALYSIS SHOWED AN INTERACTION BETWEEN TIME AND GROUP IN DACC, INDICATING A TREND TOWARDS INCREASED GRAY MATTER VOLUME AFTER THE MET INTERVENTION. (1)H-MRS ANALYSIS SHOWED AN INTERACTION BETWEEN TIME AND GROUP IN CHOLINE-CONTAINING COMPOUNDS IN BILATERAL HIPPOCAMPUS, INDUCED BY SIGNIFICANT DECREASES AFTER THE MET INTERVENTION. THOUGH PRELIMINARY, OUR RESULTS SUGGEST THAT MEMORY TRAINING INDUCES STRUCTURAL AND NEUROCHEMICAL PLASTICITY IN SENIORS WITH MCI. FURTHER RESEARCH IS NEEDED TO DETERMINE WHETHER MIND-BODY INTERVENTIONS LIKE YOGA YIELD SIMILAR NEUROPLASTIC CHANGES.	2016	
                                                                                                                                                                                 
8 1458  20 INFLUENCE OF YOGA ON BLOOD COAGULATION. YOGA IS KNOWN TO INDUCE BENEFICIAL EFFECTS ON PHYSIOLOGICAL, BIOCHEMICAL AND MENTAL FUNCTIONS IN MAN. ITS EFFECTS ON BLOOD COAGULATION ARE NOT KNOWN. A STUDY WAS CONDUCTED IN SEVEN PREVIOUSLY UNTRAINED MALE ADULTS WHO UNDERWENT A COMBINATION OF YOGIC EXERCISES, DAILY FOR ONE HOUR, OVER A PERIOD OF FOUR MONTHS. PARAMETERS OF BLOOD COAGULATION WERE ESTIMATED BEFORE AND AFTER THE END OF YOGA TRAINING. THE FOLLOWING CHANGES WERE OBSERVED: FIBRINOLYTIC ACTIVITY INCREASED SIGNIFICANTLY WITH A CONCOMITANT FALL IN FIBRINOGEN; ACTIVATED PARTIAL THROMBOPLASTIN TIME AND PLATELET AGGREGATION TIME WERE PROLONGED; BLOOD AND PLASMA PLATELETS SHOWED A RISE; AND BOTH HAEMOGLOBIN AND HEAMATOCRIT WERE RAISED AT THE END OF THE TRAINING. THESE FINDINGS SUGGEST THAT YOGA INDUCES A STATE OF BLOOD HYPOCOAGULABILITY. THE IMPACT OF YOGA ON PREVENTION OF CARDIOVASCULAR AND THROMBOTIC DISORDERS IS OBVIOUS.	1984	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
9 1347  36 HYPOXIA IN CNS PATHOLOGIES: EMERGING ROLE OF MIRNA-BASED NEUROTHERAPEUTICS AND YOGA BASED ALTERNATIVE THERAPIES. CELLULAR RESPIRATION IS A VITAL PROCESS FOR THE EXISTENCE OF LIFE. ANY CONDITION THAT RESULTS IN DEPRIVATION OF OXYGEN (ALSO TERMED AS HYPOXIA) MAY EVENTUALLY LEAD TO DELETERIOUS EFFECTS ON THE FUNCTIONING OF TISSUES. BRAIN BEING THE HIGHEST CONSUMER OF OXYGEN IS PRONE TO INCREASED RISK OF HYPOXIA-INDUCED NEUROLOGICAL INSULTS. THIS IN TURN HAS BEEN ASSOCIATED WITH MANY DISEASES OF CENTRAL NERVOUS SYSTEM (CNS) SUCH AS STROKE, ALZHEIMER'S, ENCEPHALOPATHY ETC. ALTHOUGH SEVERAL STUDIES HAVE INVESTIGATED THE PATHOPHYSIOLOGICAL MECHANISMS UNDERLYING ISCHEMIC/HYPOXIC CNS DISEASES, THE KNOWLEDGE ABOUT PROTECTIVE THERAPEUTIC STRATEGIES TO AMELIORATE THE AFFECTED NEURONAL CELLS IS MEAGER. THIS HAS AUGMENTED THE NEED TO IMPROVE OUR UNDERSTANDING OF THE HYPOXIC AND ISCHEMIC EVENTS OCCURRING IN THE BRAIN AND IDENTIFY NOVEL AND ALTERNATE TREATMENT MODALITIES FOR SUCH INSULTS. MICRORNA (MIRNAS), SMALL NON-CODING RNA MOLECULES, HAVE RECENTLY EMERGED AS POTENTIAL NEUROPROTECTIVE AGENTS AS WELL AS TARGETS, UNDER HYPOXIC CONDITIONS. THESE 18-22 NUCLEOTIDE LONG RNA MOLECULES ARE PROFUSELY PRESENT IN BRAIN AND OTHER ORGANS AND FUNCTION AS GENE REGULATORS BY CLEAVING AND SILENCING THE GENE EXPRESSION. IN BRAIN, THESE ARE KNOWN TO BE INVOLVED IN NEURONAL DIFFERENTIATION AND PLASTICITY. THEREFORE, TARGETING MIRNA EXPRESSION REPRESENTS A NOVEL THERAPEUTIC APPROACH TO INTERCEDE AGAINST HYPOXIC AND ISCHEMIC BRAIN INJURY. IN THE FIRST PART OF THIS REVIEW, WE WILL DISCUSS THE NEUROPHYSIOLOGICAL CHANGES CAUSED AS A RESULT OF HYPOXIA, FOLLOWED BY THE CONTRIBUTION OF HYPOXIA IN THE NEURODEGENERATIVE DISEASES. SECONDLY, WE WILL PROVIDE RECENT UPDATES AND INSIGHTS INTO THE ROLES OF MIRNA IN THE REGULATION OF GENES IN OXYGEN AND GLUCOSE DEPRIVED BRAIN IN ASSOCIATION WITH CIRCADIAN RHYTHMS AND HOW THESE CAN BE TARGETED AS NEUROPROTECTIVE AGENTS FOR CNS INJURIES. FINALLY, WE WILL EMPHASIZE ON ALTERNATE BREATHING OR YOGIC INTERVENTIONS TO OVERCOME THE HYPOXIA ASSOCIATED ANOMALIES THAT COULD ULTIMATELY LEAD TO IMPROVEMENT IN CEREBRAL PERFUSION.	2017	
                                                                                                                             
10 2564  24 YOGA FOR CONTROL OF EPILEPSY. YOGA IS AN AGE-OLD TRADITIONAL INDIAN PSYCHO-PHILOSOPHICAL-CULTURAL METHOD OF LEADING ONE'S LIFE, THAT ALLEVIATES STRESS, INDUCES RELAXATION AND PROVIDES MULTIPLE HEALTH BENEFITS TO THE PERSON FOLLOWING ITS SYSTEM. IT IS A METHOD OF CONTROLLING THE MIND THROUGH THE UNION OF AN INDIVIDUAL'S DORMANT ENERGY WITH THE UNIVERSAL ENERGY. COMMONLY PRACTICED YOGA METHODS ARE 'PRANAYAMA' (CONTROLLED DEEP BREATHING), 'ASANAS' (PHYSICAL POSTURES) AND 'DHYANA' (MEDITATION) ADMIXED IN VARYING PROPORTIONS WITH DIFFERING PHILOSOPHIC IDEAS. A REVIEW OF YOGA IN RELATION TO EPILEPSY ENCOMPASSES NOT ONLY SEIZURE CONTROL BUT ALSO MANY FACTORS DEALING WITH OVERALL QUALITY-OF-LIFE ISSUES (QOL). THIS PAPER REVIEWS ARTICLES RELATED TO YOGA AND EPILEPSY, SEIZURES, EEG, AUTONOMIC CHANGES, NEURO-PSYCHOLOGY, LIMBIC SYSTEM, AROUSAL, SLEEP, BRAIN PLASTICITY, MOTOR PERFORMANCE, BRAIN IMAGING STUDIES, AND REHABILITATION. THERE IS A DEARTH OF RANDOMIZED, BLINDED, CONTROLLED STUDIES RELATED TO YOGA AND SEIZURE CONTROL. A MULTI-CENTRE, CROSS-CULTURAL, PREFERABLY BLINDED (DIFFICULT FOR YOGA), WELL-RANDOMIZED CONTROLLED TRIAL, ESPECIALLY USING A SINGLE YOGIC TECHNIQUE IN A HOMOGENEOUS POPULATION SUCH AS JUVENILE MYOCLONIC EPILEPSY IS JUSTIFIED TO FIND OUT HOW YOGA AFFECTS SEIZURE CONTROL AND QOL OF THE PERSON WITH EPILEPSY.	2001	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
11 1836  20 PSYCHOPHYSIOLOGICAL CORRELATES OF THE PRACTICE OF TANTRIC YOGA MEDITATION. AUTONOMIC AND ELECTROENCEPHALOGRAPHIC (EEG) CORRELATES OF TANTRIC YOGA MEDITATION WERE STUDIED IN THREE GROUPS OF SUBJECTS AS THEY PROGRESSED FROM NORMAL CONSCIOUSNESS INTO MEDITATION. GROUPS DIFFERED IN THEIR LEVEL OF MEDITATION PROFICIENCY. MEASURES OF SKIN RESISTANCE, HEART RATE, RESPIRATION, AUTONOMIC ORIENTING RESPONSES, RESTING EEG, EEG ALPHA AND THETA FREQUENCIES, SLEEP-SCORED EEG, AVERAGED EVOKED RESPONSES, AND SUBJECTIVE EXPERIENCE WERE EMPLOYED. UNLIKE MOST PREVIOUSLY REPORTED MEDITATION STUDIES, PROFICIENT MEDITATORS DEMONSTRATED INCREASED AUTONOMIC ACTIVATION DURING MEDITATION WHILE UNEXPERIENCED MEDITATORS DEMONSTRATED AUTONOMIC RELAXATION. DURING MEDITATION, PROFICIENT MEDITATORS DEMONSTRATED INCREASED ALPHA AND THETA POWER, MINIMAL EVIDENCE OF EEG-DEFINED SLEEP, AND DECREASED AUTONOMIC ORIENTING TO EXTERNAL STIMULATION. AN EPISODE OF SUDDEN AUTONOMIC ACTIVATION WAS OBSERVED THAT WAS CHARACTERIZED BY THE MEDITATOR AS AN APPROACH TO THE YOGIC ECSTATIC STATE OF INTENSE CONCENTRATION. THESE FINDINGS CHALLENGE THE CURRENT "RELAXATION" MODEL OF MEDITATIVE STATES.	1978	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
12 2004  32 STUDY OF IMMEDIATE NEUROLOGICAL AND AUTONOMIC CHANGES DURING KAPALBHATI PRANAYAMA IN YOGA PRACTITIONERS. BACKGROUND: KAPALBHATI IS A FAST PACE RESPIRATORY EXERCISE OR PRANAYAM, WHICH IS SUPPOSED TO BE PRACTICED BY YOGIS TO CLEAN THEIR BRAIN. PRANAYAMAS ARE WELL KNOWN TO IMPROVE HEART RATE VARIABILITY (HRV) ULTIMATELY LEADING TO BETTER AUTONOMIC FUNCTIONS. OTHER STUDIES HAVE OBSERVED THE IMMEDIATE EFFECT OF KAPALBHATI ON VARIOUS NEUROLOGICAL (BRAIN AND SPINE) AND AUTONOMIC FUNCTIONS, BUT THEIR RESULTS ARE VARIED AND INCONCLUSIVE. OBJECTIVE: THE AIM OF THIS STUDY IS TO FIND OUT THE CHANGES IN HRV AND BRAIN WAVES DURING AND AFTER PRACTICE OF KAPALBHATI AS COMPARED WITH THE BASELINE VALUES OF DIFFERENT PARAMETERS. METHODS: VARIOUS PARAMETERS WERE MEASURED AT BASELINE, DURING AND AFTER KAPALBHATI PRANAYAM WITH THE HELP OF DINAMIKA HRV-ADVANCED HRV TEST SYSTEM, MOSCOW, RUSSIA. STATISTICAL ANALYSIS WAS ACCOMPLISHED EMPLOYING REPEATED MEASURES ANALYSIS OF VARIANCE WITH BONFERRONI POST-HOC ANALYSIS AND HOLM'S MULTIPLE COMPARISONS USING THE VERSION 28.0.0.0 OF THE STATISTICAL PACKAGE FOR THE SOCIAL SCIENCES (SPSS) FOR WINDOWS (190) SPSS INC., CHICAGO. RESULTS: WE FOUND THAT DURING AND AFTER KAPALBHATI, CHANGES IN HRV WERE SIGNIFICANT IN TIME AND FREQUENCY DOMAIN SHOWING PARASYMPATHETIC WITHDRAWAL AND INSIGNIFICANT CHANGES IN BRAIN WAVES AS COMPARED WITH REFERENCE POINT VALUES. CONCLUSION: KAPALBHATI IS INITIALLY ENERGIZING, CLEANSING, AND HEATING. THERE OCCURS PARASYMPATHETIC WITHDRAWAL AND SYMPATHETIC ACTIVATION DURING PRANAYAMA. THERE IS AN INCREASE GAMMA WAVE ACTIVATION POST PRANAYAMA SHOWING CONTROL OF THE DEFAULT MODE NETWORK.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
13 1112  23 EFFICACY AND TOLERABILITY OF YOGA BREATHING IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE: A PILOT STUDY. PURPOSE: YOGA-DERIVED BREATHING HAS BEEN REPORTED TO IMPROVE GAS EXCHANGE IN PATIENTS WITH CHRONIC HEART FAILURE AND IN PARTICIPANTS EXPOSED TO HIGH-ALTITUDE HYPOXIA. WE INVESTIGATED THE TOLERABILITY AND EFFECT OF YOGA BREATHING ON VENTILATORY PATTERN AND OXYGENATION IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD). METHODS: PATIENTS WITH COPD (N = 11, 3 WOMEN) WITHOUT PREVIOUS YOGA PRACTICE AND TAKING ONLY SHORT-ACTING BETA2-ADRENERGIC BLOCKING DRUGS WERE ENROLLED. VENTILATORY PATTERN AND OXYGEN SATURATION WERE MONITORED BY MEANS OF INDUCTIVE PLETHYSMOGRAPHY DURING 30-MINUTE SPONTANEOUS BREATHING AT REST (SB) AND DURING A 30-MINUTE YOGA LESSON (Y). DURING THE YOGA LESSON, THE PATIENTS WERE REQUESTED TO MOBILIZE IN SEQUENCE THE DIAPHRAGM, LOWER CHEST, AND UPPER CHEST ADOPTING A SLOWER AND DEEPER BREATHING. WE EVALUATED OXYGEN SATURATION (SAO2%), TIDAL VOLUME (VT), MINUTE VENTILATION (E), RESPIRATORY RATE (I>F), INSPIRATORY TIME, TOTAL BREATH TIME, FRACTIONAL INSPIRATORY TIME, AN INDEX OF THORACOABDOMINAL COORDINATION, AND AN INDEX OF RAPID SHALLOW BREATHING. CHANGES IN DYSPNEA DURING THE YOGA LESSON WERE ASSESSED WITH THE BORG SCALE. RESULTS: DURING THE YOGA LESSON, DATA SHOWED THE ADOPTION OF A DEEPER AND SLOWER BREATHING PATTERN (VTSB L 0.54[0.04], VTY L 0.74[0.08], P = .01; I>FSB 20.8[1.3], I>FY 13.8[0.2], P = .001) AND A SIGNIFICANT IMPROVEMENT IN SAO2% WITH NO CHANGE IN E (SAO2%SB 91.5%[1.13], SAO2%Y 93.5%[0.99], P = .02; ESB L/MIN 11.2[1.1], EY L/MIN 10.2[0.9]). ALL THE PARTICIPANTS REPORTED TO BE COMFORTABLE DURING THE YOGA LESSON, WITH NO INCREASE IN DYSPNEA INDEX. CONCLUSION: WE CONCLUDE THAT SHORT-TERM TRAINING IN YOGA IS WELL TOLERATED AND INDUCES FAVORABLE RESPIRATORY CHANGES IN PATIENTS WITH COPD.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                           
14  448  33 CHANGES IN AUTONOMIC VARIABLES FOLLOWING TWO MEDITATIVE STATES DESCRIBED IN YOGA TEXTS. OBJECTIVES: IN ANCIENT YOGA TEXTS THERE ARE TWO MEDITATIVE STATES DESCRIBED. ONE IS DHARANA, WHICH REQUIRES FOCUSING, THE SECOND IS DHYANA, DURING WHICH THERE IS NO FOCUSING, BUT AN EXPANSIVE MENTAL STATE IS REACHED. WHILE AN EARLIER STUDY DID SHOW IMPROVED PERFORMANCE IN AN ATTENTION TASK AFTER DHARANA, THE AUTONOMIC CHANGES DURING THESE TWO STATES HAVE NOT BEEN STUDIED. METHODS: AUTONOMIC AND RESPIRATORY VARIABLES WERE ASSESSED IN 30 HEALTHY MALE VOLUNTEERS (GROUP MEAN AGE +/- SD, 29.1 +/- 5.1 YEARS) DURING FOUR MENTAL STATES DESCRIBED IN TRADITIONAL YOGA TEXTS. THESE FOUR MENTAL STATES ARE RANDOM THINKING (CANCALATA), NONMEDITATIVE FOCUSING (EKAGRATA), MEDITATIVE FOCUSING (DHARANA), AND EFFORTLESS MEDITATION (DHYANA). ASSESSMENTS WERE MADE BEFORE (5 MINUTES), DURING (20 MINUTES), AND AFTER (5 MINUTES), EACH OF THE FOUR STATES, ON FOUR SEPARATE DAYS. RESULTS: DURING DHYANA THERE WAS A SIGNIFICANT INCREASE IN THE SKIN RESISTANCE LEVEL (P<0.001; POST HOC ANALYSIS FOLLOWING ANOVA, DURING COMPARED TO PRE) AND PHOTO-PLETHYSMOGRAM AMPLITUDE (P<0.05), WHEREAS THERE WAS A SIGNIFICANT DECREASE IN THE HEART RATE (P<0.001) AND BREATH RATE (P<0.001). THERE WAS A SIGNIFICANT DECREASE IN THE LOW FREQUENCY (LF) POWER (P<0.001) AND INCREASE IN THE HIGH FREQUENCY (HF) POWER (P<0.001) IN THE FREQUENCY DOMAIN ANALYSIS OF THE HEART RATE VARIABILITY (HRV) SPECTRUM, ON WHICH HF POWER IS ASSOCIATED WITH PARASYMPATHETIC ACTIVITY. THERE WAS ALSO A SIGNIFICANT INCREASE IN THE NN50 COUNT (THE NUMBER OF INTERVAL DIFFERENCES OF SUCCESSIVE NN INTERVALS GREATER THAN 50 MS; P<0.001) AND THE PNN50 (THE PROPORTION DERIVED BY DIVIDING NN50 BY THE TOTAL NUMBER OF NN INTERVALS; P<0.001) IN TIME DOMAIN ANALYSIS OF HRV, BOTH INDICATIVE OF PARASYMPATHETIC ACTIVITY. CONCLUSIONS: MAXIMUM CHANGES WERE SEEN IN AUTONOMIC VARIABLES AND BREATH RATE DURING THE STATE OF EFFORTLESS MEDITATION (DHYANA). THE CHANGES WERE ALL SUGGESTIVE OF REDUCED SYMPATHETIC ACTIVITY AND/OR INCREASED VAGAL MODULATION. DURING DHARANA THERE WAS AN INCREASE IN SKIN RESISTANCE. THE CHANGES IN HRV DURING EKAGRATA AND CANCALATA WERE INCONCLUSIVE.	2013	
                                                                               
15 1590  21 MEDITATION AND YOGA CAN MODULATE BRAIN MECHANISMS THAT AFFECT BEHAVIOR AND ANXIETY-A MODERN SCIENTIFIC PERSPECTIVE. MEDITATION AND YOGA TECHNIQUES ARE RECEIVING INCREASED ATTENTION THROUGHOUT THE WORLD, DUE TO THE ACCUMULATION OF EVIDENCE BASED RESEARCH THAT PROVES THE DIRECT AND INDIRECT BENEFITS OF SUCH PRACTICES. BASED ON STUDIES CONDUCTED SO FAR, IT HAS BEEN FOUND THAT THE PRACTICE OF MEDITATION TRIGGERS NEUROTRANSMITTERS THAT MODULATE PSYCHOLOGICAL DISORDERS SUCH AS ANXIETY. THIS PAPER WILL REVIEW THE PSYCHOLOGICAL EFFECTS OF THE PRACTICE OF MEDITATION, THE ROLE OF NEUROTRANSMITTERS, AND STUDIES USING EEG AND FMRI.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
16 1639  27 MODULATION OF IMMUNE RESPONSES IN STRESS BY YOGA. STRESS IS A CONSTANT FACTOR IN TODAY'S FASTPACED LIFE THAT CAN JEOPARDIZE OUR HEALTH IF LEFT UNCHECKED. IT IS ONLY IN THE LAST HALF CENTURY THAT THE ROLE OF STRESS IN EVERY AILMENT FROM THE COMMON COLD TO AIDS HAS BEEN EMPHASIZED, AND THE MECHANISMS INVOLVED IN THIS PROCESS HAVE BEEN STUDIED. STRESS INFLUENCES THE IMMUNE RESPONSE PRESUMABLY THROUGH THE ACTIVATION OF THE HYPOTHALAMIC-PITUITARY ADRENAL AXIS, HYPOTHALAMIC PITUITARY-GONADAL AXIS, AND THE SYMPATHETIC-ADRENAL-MEDULLARY SYSTEM. VARIOUS NEUROTRANSMITTERS, NEUROPEPTIDES, HORMONES, AND CYTOKINES MEDIATE THESE COMPLEX BIDIRECTIONAL INTERACTIONS BETWEEN THE CENTRAL NERVOUS SYSTEM (CNS) AND THE IMMUNE SYSTEM. THE EFFECTS OF STRESS ON THE IMMUNE RESPONSES RESULT IN ALTERATIONS IN THE NUMBER OF IMMUNE CELLS AND CYTOKINE DYSREGULATION. VARIOUS STRESS MANAGEMENT STRATEGIES SUCH AS MEDITATION, YOGA, HYPNOSIS, AND MUSCLE RELAXATION HAVE BEEN SHOWN TO REDUCE THE PSYCHOLOGICAL AND PHYSIOLOGICAL EFFECTS OF STRESS IN CANCERS AND HIV INFECTION. THIS REVIEW AIMS TO DISCUSS THE EFFECT OF STRESS ON THE IMMUNE SYSTEM AND EXAMINE HOW RELAXATION TECHNIQUES SUCH AS YOGA AND MEDITATION COULD REGULATE THE CYTOKINE LEVELS AND HENCE, THE IMMUNE RESPONSES DURING STRESS.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
17 1670  20 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
18 1578  35 MEASUREMENT OF THE EFFECT OF ISHA YOGA ON CARDIAC AUTONOMIC NERVOUS SYSTEM USING SHORT-TERM HEART RATE VARIABILITY. BACKGROUND: BENEFICIAL EFFECTS OF YOGA HAVE BEEN POSTULATED TO BE DUE TO MODULATION OF THE AUTONOMIC NERVOUS SYSTEM. OBJECTIVE: TO ASSESS THE EFFECT OF ISHA YOGA PRACTICES ON CARDIOVASCULAR AUTONOMIC NERVOUS SYSTEM THROUGH SHORT-TERM HEART RATE VARIABILITY (HRV). DESIGN OF THE STUDY: SHORT-TERM HRV OF LONG-TERM REGULAR HEALTHY 14 (12 MALES AND 2 FEMALES) ISHA YOGA PRACTITIONERS WAS COMPARED WITH THAT OF AGE- AND GENDER-MATCHED 14 (12 MALES AND 2 FEMALES) NON-YOGA PRACTITIONERS. METHODS AND MATERIALS: ECG LEAD II AND RESPIRATORY MOVEMENTS WERE RECORDED IN BOTH GROUPS USING POLYRITE DURING SUPINE REST FOR 5 MIN AND CONTROLLED DEEP BREATHING FOR 1 MINUTE. FREQUENCY DOMAIN ANALYSIS [RR INTERVAL IS THE MEAN OF DISTANCE BETWEEN SUBSEQUENT R WAVE PEAKS IN ECG], LOW FREQUENCY (LF) POWER, HIGH FREQUENCY (HF) POWER, LF NORMALIZED UNITS (NU), HF NU, LF/HF RATIO] AND TIME DOMAIN ANALYSIS [STANDARD DEVIATION OF NORMAL TO NORMAL INTERVAL (SDNN), SQUARE OF MEAN SQUARED DIFFERENCE OF SUCCESSIVE NORMAL TO NORMAL INTERVALS (RMSSD), NORMAL TO NORMAL INTERVALS WHICH ARE DIFFERING BY 50 MS (NN50), AND PERCENTAGE OF NN50 (PNN50)] OF HRV VARIABLES WERE ANALYZED FOR SUPINE REST. TIME DOMAIN ANALYSIS WAS RECORDED FOR DEEP BREATHING. RESULTS: RESULTS SHOWED STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN ISHA YOGA PRACTITIONERS AND CONTROLS IN BOTH FREQUENCY AND TIME DOMAIN ANALYSES OF HRV INDICES, WITH NO DIFFERENCE IN RESTING HEART RATE BETWEEN THE GROUPS. CONCLUSIONS: PRACTITIONERS OF ISHA YOGA SHOWED WELL-BALANCED BENEFICIAL ACTIVITY OF VAGAL EFFERENTS, AN OVERALL INCREASED HRV, AND SYMPATHOVAGAL BALANCE, COMPARED TO NON-YOGA PRACTITIONERS DURING SUPINE REST AND DEEP BREATHING.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19 1266  16 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
20 1698  28 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
