-Abstract-
Every day we experience profound changes in mental and physical condition as body
and brain alternate between states of high activity during the waking day and
recuperation, rest, and repair during night time sleep. In human and other mammals the
primary body clock is located in the suprachiasmatic nuclei. The circadian pacemaker
located in the suprachiasmatic nucleus of the hypothalamus regulates the timing and
consolidation of sleep. There are many the circadian sleep-wake cycle disorder and the
growing use of activity-based monitoring(actigraphy) in sleep disorder has enriched and
challenged traditional sleep-monitoring technique. Actigraphy provides useful measures of
sleep-wake schedule and sleep quality.
