Quizplus · Accepted Answer

The tectum, specifically the superior colliculus, is responsible for detecting and orienting to auditory and visual stimuli. In this case, Andy's head turning towards the sound of the car horn is a reflexive response mediated by the tectum. The medulla and hypothalamus are not directly involved in sensory processing and the cerebellum is primarily involved in motor coordination and balance.
