Study on the EEG Rhythm in Meditation

Abstract

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