Question

Quizplus · Accepted Answer

The reticular activating system (RAS) is a network of neurons located in the brainstem that plays a key role in regulating arousal and alertness. It receives sensory information from various sources and determines which stimuli to attend to, thus influencing levels of consciousness and wakefulness. The other options (cerebellum, hippocampus, basal ganglia) are involved in different functions such as motor coordination, learning and memory, and movement planning, respectively, but not in arousal.
