2-Minute Neuroscience: Vestibulocochlear Nerve (Cranial Nerve VIII)

The vestibulocochlear nerve (cranial nerve VIII) is responsible for carrying information to the brain from the vestibular system and the cochlea. The information from the cochlea deals with hearing, while the information from the vestibular system deals with vestibular sensations, which include information about head position and movement. These vestibular sensations enable us to keep our balance, stabilize our head and body during movement, and maintain posture. In this video, I discuss the anatomy and function of the vestibulocochlear nerve, as well as what symptoms can appear when the nerve is damaged.
