Non-rapid eye movement sleep with low muscle tone as a marker of rapid eye movement sleep regulation

摘要

BackgroundIt was recently reported that epochs of non-REM sleep (NREMS) with low muscle tone represent a partial correlate of REM sleep (REMS). To further investigate this phenomenon, episodes of restricted night-time sleep (23:00 – 03.00h) and subsequent morning sleep (10:00 – 13:00h) were analysed.
