Pranayama Yoga: Measuring Brainwaves via EEG

Abstract

Differences in baseline electroencephalogram (EEG) activity have been found among long-time practitioners of meditation (3+ years) in comparison to novice meditators (<1 year). In the current study, 10 participants (5 experienced meditators; 5 novices) engaged in a series of weekly, 20-minute Open Heart Meditation (OHM) practices; 5 control participants (all novices) engaged in a 20-minute reading/study session. EEG activity was measured in all participants during the first and final sessions. While the differences did not reach statistical significance, there were differences in the expected direction, suggesting an increase in baseline mean frequency of EEG measurements within the beta range for experienced meditators in comparison to novices and controls, suggesting an increase in neurological engagement during meditation. These findings suggest that there are potential neurological gains of certain meditative practices, which should lead to further investigation into the merits of meditative practice as a form of therapy.
