Question 3

Describe the role of the reticular activating system in cortical arousal and stimulation.

Accepted Answer

The reticular activating system (RAS) appears to mediate the alertness state of the cerebral cortex. The thalamus, hypothalamus, and other areas such as the brain stem appear to be interconnected with the RAS. The hypothalamus seems to be the structure responsible for the actual timing of the sleep-wake cycle. The primary neurotransmitter involved is serotonin.
