Neuroanatomy, cranial nerve 9 (glossopharyngeal). These impulses are then perceived and interpreted by the brain as. Neuroanatomy, cranial nerve 12 (hypoglossal). The human ears purpose in the area of hearing is to convert sound waves into nerve impulses. They have the ability to respond to stimuli from a much longer distance than visual sensations. In a way, however, auditory sensations are even more important than visual sensations. Neuroanatomy, cranial nerve 10 (vagus nerve). Introduction to Auditory Sensation: The auditory sensation or the sensation of hearing is next in importance only to visual sensations. The cochlear nerve is responsible for hearing by transmitting auditory signals from the inner ear to the cochlear nuclei within the brainstem, and ultimately to. Neuroanatomy, cranial nerve 1 (olfactory). Neuroanatomy, cranial nerve 11 (accessory). Mutations in several genes have been associated to the most forms of AN. Neuroanatomy, cranial nerve 8 (vestibulocochlear). The auditory nerve enters the brain and divides into two, with the ascending branch projecting to the anterior region of the ventral cochlear nucleus (VCN) and the descending branch to the posterior region of the VCN and to the new DCN. Auditory Neuropathy (AN) is characterized by disruption of temporal coding of acoustic signals in auditory nerve fibers resulting in alterations of auditory perceptions.

As hair cells become activated, they generate neural impulses that travel along the auditory nerve to the brain. The activation of hair cells is a mechanical process: the stimulation of the hair cell ultimately leads to activation of the cell.

The basilar membrane is a thin strip of tissue within the cochlea.
