A quantitative investigation of the EEG during hypnosis was made by analyzing the analogue power frequency spectrum of one group of subjects in the awake and hypnotized conditions, and another group (random sample) in the awake condition. Individuals of the first group were thoroughly experienced in self-hypnosis and highly hypnotizable, whereas those of the second group had never been hypnotized and were low in waking suggestibility. There were no statistically significant differences in mean power of the whole EEG spectrum between the awake and hypnotized conditions of the experimental group, although a trend toward increased theta (4 to 8 Hz) density during hypnosis was apparent. This group, however, exhibited significantly more theta activity during both the hypnotized and the awake conditions than the random sample of controls in the awake condition, irrespective of whether the eyes were closed or open. We suggest that this increased theta density in the EEG is related to frequent experience of self-hypnosis, high hypnotizability, or both.
通过分析一组受试者在清醒和催眠状态下的模拟功率频谱,以及另一组(随机样本)在清醒状态下的模拟功率频谱,对催眠期间的脑电图进行了定量研究。第一组个体在自我催眠方面经验丰富且极易被催眠,而第二组个体从未被催眠过,且清醒时的暗示性较低。尽管在催眠期间θ波(4至8赫兹)密度有增加的趋势,但实验组在清醒和催眠状态下整个脑电图频谱的平均功率在统计学上没有显著差异。然而,无论眼睛是睁开还是闭上,该组在催眠和清醒状态下都比清醒状态下的随机对照组表现出明显更多的θ波活动。我们认为脑电图中这种增加的θ波密度与频繁的自我催眠体验、高度的催眠易感性或两者都有关。
