The Effects of Concentrative Meditation on the Electroencephalogram in Novice Meditators
Clinical EEG and Neuroscience March 1, 2023 Alexander T. Duda, Adam R. Clarke, Frances M. De Blasio et al.
Novice meditators who practiced daily concentrative meditation for about a month showed changes in specific brain wave components during both meditation and resting states. Using frequency Principal Components Analysis (f-PCA), four spectral components were identified: Delta-Theta-Alpha, Low Alpha, High Alpha, and Alpha-Beta. All four components increased during meditation at the second session, but only Low Alpha (around 9.5-10.0 Hz) showed similar increases during resting. The findings support f-PCA as a novel method for analyzing psychophysiological states in meditation research.
