Meditators and non-meditators: EEG source imaging during resting.
Brain Topography November 1, 2009 Shisei Tei, Pascal L Faber, Dietrich Lehmann et al.
Long-term meditation practice may change the brain in ways that persist even when not meditating. Comparing Qigong meditators with non-meditators using EEG during rest, the meditators showed reduced activity in brain regions involved in judging or appraising, and increased activity in areas that process sensory information from inside and outside the body. These differences in delta brain waves suggest that the subjective experiences of greater awareness and detachment reported by experienced meditators are supported by lasting neuroplastic changes that carry over into everyday life.
