Question

Quizplus · Accepted Answer

The reticular activating system (RAS) is a network of neurons located in the brainstem that plays a crucial role in arousal and attention. It filters incoming information and determines what information reaches the cortex. The other options, cerebellum, medulla, and pons, are also parts of the brainstem but do not have the same functions as the RAS.
