Hypnosis can be seen as a guided induction of various states of consciousness. This article details a time-series analysis that visualized the electrophysiological state changes during a session as a correlate to the instructions. Sixty-four channels of EEG and peripheral physiological measures were recorded in 1 highly susceptible subject. Significant state changes occurred synchronously with specific induction instructions. Some patterns could be physiologically explained, such as sensorimotor desynchronization over the right hemispheric hand area during left arm levitation. There was a highly significant increase in broadband activity during the stepwise trance induction that may point to a deep hypnotic state. This study provides illustrated proof for the detectability of physiological state changes as correlates to different states of awareness, consciousness, or cognition during hypnosis.
催眠可以被视为对各种意识状态的引导性诱导。本文详细介绍了一项时间序列分析，该分析将会话期间的电生理状态变化可视化，作为与指令相关的指标。在一位高度易感性的受试者中记录了 64 通道的 EEG 和外周生理测量值。随着特定的诱导指令，出现了显著的状态变化。一些模式可以从生理学上解释，例如在左臂悬浮时，右侧半球手部区域的感觉运动去同步。在逐步催眠诱导过程中，宽带活动显著增加，这可能表明进入了深度催眠状态。这项研究为在催眠过程中检测不同意识、意识或认知状态的生理状态变化作为相关指标提供了实例证明。
