Question

Quizplus · Accepted Answer

The midbrain is responsible for the reflexive response of turning the head towards a loud noise. This reflex is known as the acoustic startle reflex and is an important part of the defensive behavior of animals. The midbrain integrates sensory information and coordinates motor responses, including the movement of the head in response to a sudden sound. The other brain structures listed (primary auditory cortex, secondary auditory cortex, and pons) are all involved in auditory processing, but they are not specifically responsible for the initial reflexive response to a loud noise.
