 Abstract: 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.
