A brief daily concentrative meditation practice for one month increased four EEG spectral components during meditation, with Low Alpha (∼9.5-10.0 Hz) also increasing during resting states.

Does brief daily concentrative meditation practice alter EEG frequency components in novice meditators?
Concentrative meditation practice for one month increases specific EEG spectral components, particularly Low Alpha, supporting f-PCA for analyzing psychophysiological states.
Following investigations into the benefits of meditation on psychological health and well-being, research is now seeking to understand the mechanisms underlying these outcomes. This study aimed to identify natural alpha and theta frequency components during eyes-closed resting and concentrative meditation states and examined their differences within and between two testing sessions. Novice meditators had their EEG recorded during eyes-closed resting and concentrative meditation conditions, before and after engaging in a brief daily concentrative meditation practice for approximately one-month. Separate frequency Principal Components Analyses (f-PCA) yielded four spectral components of interest, congruent between both conditions and sessions: Delta-Theta-Alpha, Low Alpha, High Alpha, and Alpha-Beta. While all four components showed some increase in the meditation condition at the second session, only Low Alpha (∼9.5-10.0 Hz) showed similar increases while resting. These findings support the use of f-PCA as a novel method of data analysis in the investigation of psychophysiological states in meditation.
Duda et al. (Mon,) conducted a observational in Healthy novice meditators. Brief daily concentrative meditation practice vs. Baseline (before practice) and eyes-closed resting state was evaluated on Natural alpha and theta frequency components (EEG spectral components). A brief daily concentrative meditation practice for one month increased four EEG spectral components during meditation, with Low Alpha (∼9.5-10.0 Hz) also increasing during resting states.
