 note = {The purpose of the present study was to determine when in the transitional period from NREM sleep to
REM sleep the cortical activity characterizing REM sleep begins to occur in man, using AEP with long latency
as an index. In 10 of 12 subjects examined, the amplitude of N300, a component of the cortical auditory
evoked potential, was evidently smaller in REM sleep than in non-REM sleep. The start of the reduction of
N300 associated with the onset of REM sleep was estimated in these 10 subjects. In 5 of them, a marked
reduction of the N300 amplitude occurred 0.5 to 2.5 minute just preceding the appearance of muscle atonia of
REM sleep. In 2 subjects, a similarly marked reduction of the N300 amplitude occurred 0.5 to 1.0 minute just
preceding the disappearance of sleep spindles or K-complexes. The present results suggest that the
physiological phenomena characterizing REM sleep do not always begin simultaneously, and that in man, the
brain electrical activity characterizing REM sleep often occurs a few minutes or less prior to the other two
physiological phenomena characterizing REM sleep, muscle atonia and rapid eye movements.},
