Variability and predictability in human sleep.

ABSTRACT: The quality of sleep and its cognitive benefits rely on the cyclic alternance of two distinct sleep stages associated (REM) or not (NREM) with rapid-eye-movements. The ability to predict shifts in sleep stages could help design future interventions in sleep medicine, but it remains unknown how robust the NREM-REM sleep architecture may be for a given individual over many successive nights. We sought to characterize the individual variability and test the predictability of healthy human sleep recorded longitudinally over unprecedented durations (weeks). Based on ultra-long-term sub-scalp electroencephalographic recordings from a newly available, minimally invasive device, we characterized sleep cycles in eight healthy subjects over a median of 30 consecutive days. We first decomposed EEG si
