In a study designed to identify the electrophysiologic characteristics of the Transcendental Meditation Program, 52 periods of spontaneous respiratory suspension (RS) were observed in 18 subjects during the practice of this program. These periods were correlated with some but not all the subjective experiences of pure consciousness. Nineteen RS periods (belonging to 11 subjects) free from any artifact were selected for EEG analysis. The mean total EEG coherence over all frequencies and over nine derivations for TM subjects showed a significant increase during the RS periods as compared to pre- and post-RS control periods. There was no significant change in mean total EEG coherence in a control group of 30 subjects voluntarily holding their breath. The heart rate showed a significant decrease during the RS periods in both the experimental and control groups, whereas there was no significant change in EEG alpha power in either group. These findings extend those of previous studies and help characterize the physiologic correlates of the state of pure consciousness during the TM program.
在一项旨在确定超觉静坐法电生理特征的研究中，18名受试者在进行该方法的过程中观察到了52次自发性呼吸暂停（RS）。这些时段与部分而非全部的纯粹意识主观体验相关。选取了19次无任何伪迹的RS时段（属于11名受试者）进行脑电图分析。与RS前和RS后的对照时段相比，超觉静坐法受试者在所有频率和九个导联上的脑电图总相干均值在RS时段显著增加。在30名自愿屏气的对照组受试者中，脑电图总相干均值无显著变化。在RS时段，实验组和对照组的心率均显著下降，而两组的脑电图α波功率均无显著变化。这些发现扩展了先前研究的结果，并有助于描述超觉静坐法过程中纯粹意识状态的生理关联特征。
