This study (N = 37 with high, medium, and low hypnotizables) evaluated depth reports and EEG activity during both voluntary and hypnotically induced left-arm lifting with sLORETA functional neuroimaging. The hypnotic condition was associated with higher activity in fast EEG frequencies in anterior regions and slow EEG frequencies in central-parietal regions, all left-sided. The voluntary condition was associated with fast frequency activity in right-hemisphere central-parietal regions and slow frequency activity in left anterior regions. Hypnotizability did not have a significant effect on EEG activity, but hypnotic depth correlated with left hemisphere increased anterior slow EEG and decreased central fast EEG activity. Hypnosis had a minimal effect on depth reports among lows, a moderate one among mediums, and a large one among highs. Because only left-arm data were available, the full role of the hemispheres remains to be clarified.
这项研究(N=37 名高、中、低催眠易感性被试)使用 sLORETA 功能神经影像学评估了自愿和催眠诱导的左手臂抬起时的深度报告和 EEG 活动。催眠状态与前区快 EEG 频率和中央顶区慢 EEG 频率的更高活动相关,均为左侧。自愿状态与右半球中央顶区的快频率活动和左前区的慢频率活动相关。催眠易感性对 EEG 活动没有显著影响,但催眠深度与左半球前部慢 EEG 增加和中央快 EEG 活动减少相关。催眠对低催眠者的深度报告影响较小,对中催眠者的影响中等,对高催眠者的影响较大。由于只有左手臂的数据可用,因此仍需阐明半球的全部作用。
