Summary

The ultradian NREM-REM sleep cycle is embedded within the larger twenty-four- hour circadian cycle. The sleep cycle interacts with the circadian cycle, which in turn is controlled by the SCN master clock within the hypothalamus. The two-process model captures interactions between the circadian process and the sleep cycle. Disorders of biological rhythmicity such as delayed sleep phase syndrome and manic depression have significant but treatable effects on sleep.
