Question

Quizplus · Accepted Answer

The reticular activating system is responsible for screening and filtering incoming information and arousing higher centres when necessary, such as in response to a child crying out for their mother. The cerebellum, medulla, and pons are all parts of the brainstem that are responsible for different functions such as motor coordination, breathing, and regulation of vital functions, but are not as directly involved in screening incoming information.
