Question

If you are reading and you unexpectedly hear a loud noise, your head generally snaps up. which portion of the midbrain is most likely to be responsible for this reflexive motion?

Answer 1

The inferior colliculus would be the most likely responsible for making you snap your head. The inferior colliculus consists of three parts, the first is the central nucleus a second one is the dorsal cortex and the third one is external cortex. This part of the midbrain is located just slightly below the superior colliculus
