Abstract

IN 10 of 12 subjects examined, the amplitude of N300, a component of the cortical auditory evoked potential, was evidently smaller in rapideye movement (REM) sleep than in non-REM sleep. The start of the reduction associated with the onset of the first episode of REM sleep was examined in these 10 subjects. In five of these, a marked reduction ofN300 amplitude occurred 0.5-2.5 min before the appearance of muscle atonia of REM sleep. In two subjects, a similarly marked reduction of the N300 amplitude occurred 0.5-1.0 min before the disappearance of sleep spindles or K-complexes. This suggests that a suppression of the synchronizing mechanism in the cerebrum sometimes occurs briefly prior to the occurrence of other physiological phenomena associated with REM sleep.
