Question

Quizplus · Accepted Answer

The RAS receives sensory impulses from the spinal cord and relays motor impulses to the thalamus and all parts of the cerebral cortex. Polysomnography is the recording of brain waves and other physiologic variables, such as muscle activity and eye movements, during sleep. The circadian rhythms influence patterns of biological and behavioral functions, and the sleep-wake circadian rhythm is affected by the light-dark cycle.
