This chapter provides an overview of the sleep-wake cycle. We describe the nature of the electrophysiology of normal sleep and the two distinct sleep states, rapid eye movement (REM) and nonrapid eye movement (NREM). The differential endocrine, autonomic, respiratory, thermal physiology and ...

The sleep/wake cycle of 39 children, 4 to 14 months of age was observed and recorded continuously (24 h per day) over a 4-month period, one full week per month, from November 1986 through February 1987. Total sleep time per day was analyzed for the different age groups and for the ...
The sleep-wake cycle as a function of sexual orientation was investigated. Male and female, heterosexual and homosexual subjects completed a sexual-orientation questionnaire and four sets of recording sheets of activities for a 16-day period.

The story of the relation between brain serotonin, sleep and waking is long and complex. Serotonin was one of the first neurotransmitters shown to be related to the physiology of the sleep/wake cycle (Bradley, 1958; Koella and Czicman, 1966; Delorme et al., 1966; Jouvet et al., 1967; ...
The authors have integrated the major findings on the sleep-wake cycle and its performance correlates in adolescents. Basic research shows that lack of synchronicity between early school start times and the circadian rhythm of adolescents (and the sleep debt accumulated as a result) involves several...

Two new techniques for the analysis of the human sleep-wake cycle are presented and illustrated. The first is based on a wrist-worn solid-state activity monitor which can record movement activity for prolonged time periods. The method has been applied to document phase-shifts of the rest-activi...
Studies of the human “sleep-wake cycle” have practical relevance for matters ranging from duty assignments in nuclear submarines and air-traffic control towers to the staff of shifts in 24-hour factories. A. to the staff of B. to those who staff C. to the staffing of D. and staffing ...
