Quizplus · Accepted Answer

The reticular formation is a network of neurons in the brainstem that is crucial for regulating arousal, attention, and sleep/wake transitions. It receives input from sensory systems and sends output to many areas of the brain, helping to coordinate and integrate sensory information and support cognitive processes. Damage to the reticular formation can lead to disorders of arousal and consciousness, including coma and persistent vegetative state.
