Abstract：
Sleepwalking and related parasomnias result from incomplete awakenings out of non-rapid eye movement sleep. Behavioral episodes can occur without consciousness or recollection, or in relation to dream-like experiences. To understand what accounts for these differences in consciousness and recall, here we recorded parasomnia episodes with high-density electroencephalography (EEG) and interviewed participants immediately afterward about their experiences. Compared to reports of no experience (19%), reports of conscious experience (56%) were preceded by high-amplitude EEG slow waves in anterior cortical regions and activation of posterior cortical regions, similar to previously described EEG correlates of dreaming. Recall of the content of the experience (56%), compared to no recall (25%), was associated with higher EEG activation in the right medial temporal region before movement onset. Our work suggests that the EEG correlates of parasomnia experiences are similar to those reported for dreams and may thus reflect core physiological processes involved in sleep consciousness.
摘要：
梦游和相关的失眠症是由于非快速眼动睡眠引起的不完全觉醒。行为发作可以在没有意识或回忆的情况下发生，或者与梦幻般的经历有关。为了理解这些意识和回忆差异的原因，在这里,我们使用高密度脑电图(EEG)记录了失眠症发作,并随后立即采访了参与者的经历.与无经验报告(19%)相比，有意识的经验报告（56％）之前是前皮质区域的高振幅EEG慢波和后皮质区域的激活，类似于先前描述的脑电图与做梦的相关性。回忆体验的内容(56%)，与没有召回(25%)相比，在运动开始之前，右内侧颞区的EEG激活较高。我们的工作表明，睡眠状态经历的脑电图与梦中报道的脑电图相似，因此可能反映了睡眠意识中涉及的核心生理过程。
