TLDR
The study argues for the potential role of loud ‘OM’ chanting in offering relaxation, and provides a new perspective of meditation to the naive meditators, which may help to demystify meditation and encourage those considering this as beneficial practice.Abstract:
Mantra meditation is easy to practice. “OM” Mantra is the highest sacred symbol in Hinduism. The present study investigated the temporal dynamics of oscillatory changes after OM mantra meditation. Twenty-three naive meditators were asked to perform loud OM chanting for 30 min and the EEG were subsequently recorded with closed eyes before and after it. To obtain new insights into the nature of the EEG after OM chanting, EEG signals were analyzed using spectral domain analysis. Statistical analysis was performed using repeated measures of analysis of variance. It did not reveal any specific band involvement into OM mantra meditation. But significantly increase in theta power was found after meditation when averaged across all brain regions. This is the main effect of OM mantra meditation. However, the theta power showed higher theta amplitude after condition at all regions in comparison to the before condition of meditation. Finding was similar to other studies documenting reduction in cortical arousal during a state of relaxation. The study argues for the potential role of loud ‘OM’ chanting in offering relaxation. It provides a new perspective of meditation to the naive meditators. This information may help to demystify meditation and encourage those considering this as beneficial practice.read more

Spectral analysis of the central nervous system effects of the relaxation respones elicited by autogenic training
TL;DR: The results suggest that the relaxation response elicited by autogenic training produces significant acute changes in EEG activity and a characteristic spectral pattern; the results also suggest that focusing attention on a repetitive, internal stimulus is a key element in Benson's relaxation response model.

Mapping meditative states and stages with electrophysiology: concepts, classifications, and methods.
TL;DR: Questions remain to this scientific enquiry how to concisely classify discrete and developmentally specific 'mind states' of consciousness that are in line with the subtle complex phenomenology of experience so to yield ontological quantifications.

SVM classification of EEG signal to analyze the effect of OM Mantra meditation on the brain
TL;DR: Results show the significant changes in the delta band which represent the brain in deep sleep which gives the experience of deep sleep in Om mantra meditation.

The Effect of Robot-Guided Meditation on Intra-Brain EEG Phase Synchronization
TL;DR: In this article, the effect of mindfulness meditation facilitated by human-robot interaction (HRI) on brain activity was examined, where EEG signals were collected from two groups of participants; meditation group who practiced mindfulness meditation with a social robot and control group who only listened to a lecture by the robot.

An electroencephalographic study on the zen meditation (Zazen).
Akira Kasamatsu,Tomio Hirai +1 more
TL;DR: Zen meditation (ZAZEN) is a spiritual exercise held in the Zen sect of Buddhism that produces changes not only in the mind but also in the body—these influences are of interest to scientific studies, from the stand point of psychology and physiology.

TL;DR: The findings from this study suggest that nondirective meditation techniques alter theta and alpha EEG patterns significantly more than regular relaxation, in a manner that is perhaps similar to methods based on mindfulness or concentration.
