Spontaneous dissociative alterations in awareness and perception among highly suggestible individuals following a hypnotic induction may result from disruptions in the functional coordination of the frontal-parietal network. We recorded EEG and self-reported state dissociation in control and hypnosis conditions in two sessions with low and highly suggestible participants. Highly suggestible participants reliably experienced greater state dissociation and exhibited lower frontal-parietal phase synchrony in the alpha2 frequency band during hypnosis than low suggestible participants. These findings suggest that highly suggestible individuals exhibit a disruption of the frontal-parietal network that is only observable following a hypnotic induction.
高度易感性个体在催眠诱导后出现的自发分离意识和感知改变可能是由于额顶网络的功能协调中断所致。我们在两次低和高易感性参与者的会话中记录了 EEG 和自我报告的状态分离，在催眠和控制条件下。高度易感性的参与者在催眠期间比低易感性的参与者更可靠地经历更大的状态分离，并表现出较低的额顶相位同步在阿尔法 2 频段。这些发现表明，高度易感性个体表现出额顶网络的破坏，这种破坏只有在催眠诱导后才会观察到。
