Question

Quizplus · Accepted Answer

The reticular formation is a network of neurons located in the brainstem that is responsible for regulating attention and arousal. It filters out unnecessary sensory information and allows important information to reach the higher brain regions for processing. The medulla and spinal cord are primarily involved in controlling basic life-sustaining functions such as breathing and heart rate, while the thalamus is a sensory relay center that helps to direct sensory input to the appropriate regions of the brain for processing.
