Effects of hypnotic alterations of perception on amplitude of somatosensory event-related potentials were studied in 10 highly hypnotizable subjects and 10 subjects with low hypnotizability. The highly hypnotizable individuals showed significant decreases in amplitude of the P100 and P300 waveform components during a hypnotic hallucination that blocked perception of the stimulus. When hypnosis was used to intensify attention to the stimulus, there was an increase in P100 amplitude. These findings are consistent with observations that highly hypnotizable individuals can reduce or eliminate pain by using purely cognitive methods such as hypnosis. Together with data from the visual system, these results suggest a neurophysiological basis for hypnotic sensory alteration.
在10名高催眠易感性受试者和10名低催眠易感性受试者中,研究了感知的催眠改变对体感事件相关电位振幅的影响。高催眠易感性个体在阻断刺激感知的催眠幻觉期间,P100和P300波形成分的振幅显著降低。当使用催眠来增强对刺激的注意力时,P100振幅增加。这些发现与高催眠易感性个体可以通过使用催眠等纯认知方法减轻或消除疼痛的观察结果一致。与来自视觉系统的数据一起,这些结果提示了催眠感觉改变的神经生理学基础。
