The vestibulocochlear nerve is also known as the auditory vestibular nerve. It transmits sound and equilibrium (balance) information from the inner ear to the brain[1]. The eighth cranial nerve splits into the cochlear nerve and the vestibular nerve. This is a primarily sensory nerve[2]. The vestibulocochlear nerve allows us to sense sound, gravity, and body rotation[2]. If a person’s eighth cranial nerve is damaged they may experience a vertigo, hearing loss, or a false sense of movement[2].
