Quizplus · Accepted Answer

The superior colliculi are the structures in the mesencephalon responsible for integrating visual information with other sensory inputs and initiating involuntary motor responses, such as eye and head movements, in response to visual stimuli. The red nucleus and substantia nigra are involved in voluntary motor control, while the cerebral peduncles contain motor and sensory fibers connecting the cerebrum to the rest of the nervous system, but do not play a direct role in visual processing or reflexive motor responses.
