Abstract

Meditation affects the brain rhythm significantly. Compared with 4 non-meditators, the power of delta band was lower while high frequency band was 5 higher for a meditator. Alpha band over the scalp was much more active in normal 6 state for meditator with decreased dominant alpha frequency. Obvious transient 7 process between normal eyes-closed rest and meditation was observed after EEG 8 analysis. The active time and the power of beta and gamma band increased 9 significantly in meditation. The inter-hemispheric and intra-hemispheric coherence 10 beta and low gamma bands for meditative state were higher than normal state.
