C)cerebellum
D)reticular formation

Question

Quizplus · Accepted Answer

The reticular formation is a group of neurons in the brainstem that plays an important role in regulating arousal and sleep-wake transitions. It alerts the cerebral cortex to attend to new stimulation, even during sleep, by filtering sensory information and sending important stimuli to the conscious awareness. The pons, medulla, and cerebellum also play crucial roles in regulating various physiological processes but are not directly responsible for arousing the cortex during sleep. Therefore, option D is the best choice.
