Although impairment of daytime functioning is a symptom of many sleep disorders, there are limited data on their nature for some patient groups. The role of the circadian system on impaired functioning, specifically the wake maintenance zone (WMZ)-a ∼3-h window of reduced sleep propensity that occurs shortly before the onset of melatonin synthesis-has received little attention. The study examined the influence of the WMZ on neurobehavioral performance under normal conditions and following sleep deprivation.
