Quizplus · Accepted Answer

The reticular activating system (RAS) is responsible for regulating wakefulness and sleep. It receives information from various sensory pathways and sends signals to the cortex to keep us alert and awake. The light of dawn and the sound of an alarm clock can activate the RAS and lead to wakefulness. The limbic system is involved in emotions and motivation, the basal nuclei in movement control, and the cerebellar peduncles in coordination and balance.
