Chapter 28: The Circadian Cycle of Sleep and Wakefulness ... To synchronize physiological processes with the day-night cycle (called photoentrainment), the biological clock must detect decreases in light levels as night approaches. The ... circuits that ultimately govern the sleep-wake cycle (see p. 615 ff.).

Studies have found that these changes are governed by a biological clock, which in mammals is located in two brain areas called the suprachiasmatic nuclei. The circadian cycles established by this clock occur throughout nature and have a period of approximately 24 hours.
