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.
Spinal afferent fiber goes upward within spinothalamic tract and spinal tract to the thalamus (spinothalamic tract) and gracile nucleus and cuneate nucleus of medulla oblongata (spinal tract), respectively, then project fiber to thalamus through lemniscus medialis.
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.
Waves I, II, III, IV, and V originate in the ipsilateral cranial nerve VIII, cochlear nucleus, pons, lateral lemniscus, and caudal colliculus of the midbrain.
