研究目标：调查清醒梦的神经相关性。设计：夜间睡眠的并行脑电图/功能磁共振成像记录。设置：睡眠实验室和功能磁共振成像设施。参与者：四名经验丰富的清醒梦者。干预措施：不适用。测量和结果：4 名参与者中，一名受试者有 2 次经过验证的清醒快速眼动睡眠，时间足够长，可以通过功能磁共振成像进行分析。与非清醒快速眼动睡眠相比，在清醒梦期间，双侧楔前叶、楔叶、顶叶、前额叶和枕颞皮质被强烈激活。结论：根据最近的脑电图数据，清醒梦与快速眼动睡眠期间通常失活的区域的重新激活有关。这种活动模式可以解释反思认知能力的恢复，这是清醒梦的标志。
Study Objectives: To investigate the neural correlates of lucid dreaming.Design: Parallel EEG/fMRI recordings of night sleep.Setting: Sleep laboratory and fMRI facilities.Participants: Four experienced lucid dreamers.Interventions: N/A.Measurements and Results: Out of 4 participants, one subject had 2 episodes of verified lucid REM sleep of sufficient length to be analyzed by fMRI. During lucid dreaming the bilateral precuneus, cuneus, parietal lobules, and prefrontal and occipito-temporal cortices activated strongly as compared with non-lucid REM sleep.Conclusions: In line with recent EEG data, lucid dreaming was associated with a reactivation of areas which are normally deactivated during REM sleep. This pattern of activity can explain the recovery of reflective cognitive capabilities that are the hallmark of lucid dreaming.
