Question

Quizplus · Accepted Answer

The reticular activating system (RAS) receives incoming messages from the sense organs and sends them to the cortex. It also bombards the cortex with stimulation, which keeps the brain active and alert. The thalamus is involved in relaying sensory information to the cortex, but it does not have the same activating function as the RAS. The medulla is responsible for controlling vital functions such as breathing and heart rate. The limbic system is involved in emotion, memory, and motivation.
