The evoked potential is generated in the cochlea, goes through the cochlear nerve, through the cochlear nucleus, superior olivary
complex, lateral lemniscus, to the inferior colliculus in the midbrain, on to the medial geniculate body, and finally to the auditory cortex.

One of the hypotheses for the occurrence of tinnitus would be a dysfunction in the efferent auditory system, specifically in the medial superior olivary
complex (MSOC) region.
I wave originated from the peripheral portion of eighth cranial nerve adjacent to cochlea, II wave from cochlear nucleus, III wave from superior olivary
nucleus, IV wave from lateral lemniscus, and V wave from inferior colliculus.
Lesions can involve the substantia nigra, periaqueductal gray matter within the midbrain, inferior colliculus, inferior olivary
nuclei, inferior cerebellar peduncles, medulla, solitary tract in the medulla, central tegmental tract and reticular formation in the dorsal pons.

showed that the trigeminal nerve also innervates the cochlear nucleus and the superior olivary
7,11) The third migratory pathway is formed by neurons destined to become the inferior olivary
The neural generator of peak III (which is analogous to peak IV in humans) was not determined by a specific near-field recording, although the researchers' assumption was that this peak had its origin in the superior olivary
