An electrophysiological marker of #arousal level in humans

Deep non-rapid eye movement sleep (NREM) and general anesthesia with propofol are prominent states of reduced arousal linked to the occurrence of synchronized oscillations in the electroencephalogram (EEG). Although rapid eye movement (REM) sleep is also associated with diminished arousal levels, it is characterized by a desynchronized, β€˜wake-like’ EEG. This observation implies that reduced arousal …

Association of Rapid Eye Movement #Sleep With Mortality in Middle-aged and Older Adults

Rapid eye movement (#REM) sleep has been linked with health outcomes, but little is known about the relationship between REM sleep and mortality.. ..The MrOS cohort included 2675 individuals (2675 men [100%]; mean [SD] age, 76.3 [5.5] years) and was followed up for a median (interquartile range) of 12.1 (7.8-13.2) years. The WSC cohort included 1386 …
