WebJudith Kalser, Eliane Roulet-Perez, in Handbook of Clinical Neurology, 2024. CN VIII, acoustic or vestibulocochlear nerve. The acoustic or cochlear nerve is a sensory nerve essential for hearing. Together with the cochlea and the central pathway from the nucleus in the pons to the temporal cortex, it is part of the auditory system. WebThe cochlear nerve (also auditory nerve or acoustic nerve) is one of two parts of the vestibulocochlear nerve, a cranial nerve present in amniotes, the other part being the vestibular nerve. The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain.
