Percentage change in spectral power. Percentage change in spectral power before and after Sudarshan Kriya Yoga (delta, theta, alpha, beta, and gamma: represented by blue, red, black, dark green, and light green colors, respectively) in all the five frequency bands across seven regions (left frontal, right frontal, left temporal, right temporal, occipital, parietal and central). Percentage change is showing higher increase in gamma and beta power after Sudarshan Kriya Yoga as compared to delta, theta, and alpha. Topoplots are showing increase in delta, theta, alpha, beta, and gamma power after Sudarshan Kriya Yoga
