*'''Nerve Deafness''': hearing loss due to a lesion to the auditory nerve within the central neural pathway. May be congenital or genetic, for example in white cats with blue eyes or in dalmatians, a problem created due to highly selective in-breeding. Histological examinations carried out on the organ of Corti from affected dogs shows the absence of sensory cells. Nerve deafness may also be due to age.

*The signal that has been created from the sound waves that were picked up by the ear, is carried to the brain by the vestibulocochlear nerve ([[Cranial Nerves - Anatomy & Physiology|CN VIII]]), which synapses in the cochlear nucleus.
