A biological clock that governs physiological functioning and that is set by external events. A twenty-four-hour biological rhythm such as the sleep wake cycle. The exact function of sleep in uncertain. Sleep may enable us to repair cells, strengthen the immune system, recover abilities lost during the day, eliminate waste products from muscles. Infants children adults : amount of sleep lowers as age increases. Eeg has provided insight into the sleeping brain: qualitatively different stages during sleep. Stage one: feel self-drifting on the edge of consciousness. (characterized by alpha waves) Stage two: mi(cid:374)o(cid:396) (cid:374)oises do(cid:374)"t distu(cid:396)(cid:271) you.
