Introduction
This diagram gives an overview of the central neural pathway from the cochlea through the brainstem nuclei to the auditory cortex.
- auditory nerve (cochlear nerve, acoustic nerve) part of the vestibulocochlear nerve (8th cranial nerve, CN VIII)
- cochlear nuclei (dorsal cochlear nucleus, ventral cochlear nucleus)
- superior olivary complex (SOC, superior olive)
- lateral lemniscus
- inferior colliculus
- medial geniculate nucleus
- auditory cortex
Vestibulocochlear Nerve

- forms beside otocyst
- from wall of otocyst and neural crest cells
- bipolar neurons
Vestibular Neurons
- outer end of internal acoustic meatus
- innervate hair cells in membranous labyrinth
- axons project to brain stem and synapse in vestibular nucleus
Cochlear Neurons
- cell bodies lie in modiolus
- central pillar of cochlear
- innervate hair cells of spiral organ
- axons project to cochlear nucleus

Auditory Sound Localization Circuits in the Mammalian Brainstem
Schematic drawing of primary auditory sound localization circuits in the mammalian brainstem. For clarity, only the LSO or MSO are shown on each side.[2]
Except for the auditory nerve, excitatory connections are shown in green and inhibitory connections are shown in red.
- AN - auditory nerve
- CN - cochlear nucleus
- HF - high frequency
- LF - low frequency
