This is a highly
schematic representation of the auditory pathways. The auditory nerve
projects from the ear to the cochlear nucleus. The cochlear nucleus projects
to the superior olive, on both the ipsilateral (same) and contralateral
(opposite) side of the brain. Notice that information from both ears is
carried along the pathway beginning with the superior olive. The superior
olive projects to the inferior colliculus which projects to the medial
geniculate body, or nucleus. The MGB projects to the auditory cortex, in the
temporal lobe of the brain.
