咒咒很容易练习。“ OM”真言是印度教最高的神圣象征。本研究调查了OM咒语冥想后振荡变化的时间动态。要求二十三位天真的冥想者进行30分钟的大声OM诵经，随后在闭眼前后记录EEG。为了获得对OM诵经后脑电图性质的新见解，使用频谱域分析法对脑电图信号进行了分析。使用重复测量方差分析的方法进行统计分析。它没有显示出任何特定的乐队参与OM咒语冥想。但是，在所有脑区平均后，冥想后发现theta力量显着增加。这是OM咒语冥想的主要效果。然而，与冥想之前的状况相比，所有区域的theta功率表现出更高的theta振幅。该发现与其他研究相似，这些研究记录了放松状态下皮质唤醒的减少。该研究认为，大声“ OM”诵经在放松中可能具有潜在作用。它为天真的冥想者提供了一种新的冥想视角。这些信息可能有助于消除冥想的神秘感，并鼓励那些认为这是有益做法的人。

EEG Spectral Analysis on OM Mantra Meditation: A Pilot Study.

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.
