Quizplus · Accepted Answer

The reticular activating system (RAS) is responsible for regulating wakefulness and sleep. It receives input from the senses, such as the light of dawn or the sound of an alarm clock, and activates the cortex, leading to wakefulness. The basal nuclei are involved in movement control, the limbic system is involved in emotions and memory, and the cerebellar peduncles are involved in motor coordination.
