Anatomy of auditory pathway
Spiral ganglion → auditory nerve (cranial nerve VIII) → dorsal and ventral cochlear nuclei at the junction of the medulla and pons → trapezoid body (at this point 50% of the axons cross over to the other side) → superior olivary nucleus → lateral lemniscus → inferior colliculus → medial geniculate body → transverse gyrus of Heschl (area 41, partly buried in the sylvian fissure).
