![]() ![]() Asymmetry Index values tended toward 0 following SKY. Electrical activity shifted from lower to higher frequency range with a significant rise in the gamma and beta powers following SKY. Results: Spectral power increased significantly in all frequency bands bilaterally in frontal, central, parietal, temporal, and occipital regions of the brain after long SKY. Statistical Analysis: Paired t‑test was used for statistical analysis. The Asymmetry Index was calculated by subtracting the natural log of powers of left (L) hemisphere from the right® to show interhemispheric synchronization. Spectral power for delta, theta, alpha, beta, and gamma frequency band was calculated using Multi‑taper Fast Fourier Transform (Chronux toolbox). ineteen‑channel EEG was recorded and analyzed for 5 min each: before and after SKY. Subjects and Methods: Forty healthy volunteers (average age 25.45 ± 5.75, 23 males and 17 females) participated in the study. Settings and Design: This study employed before‑ and after‑study design. Aims: This study aimed to observe neuronal oscillations in multifrequency bands and interhemispheric synchronization following SKY. ![]() Sudarshan Kriya Yoga (SKY) is a popular breathing process and is established for its significant effects on the various aspects of physiology and psychology. Abstract Context: Respiration is known to modulate neuronal oscillations in the brain and is measured by electroencephalogram (EEG). ![]()
