In slightly more detail this corresponds to ear ( cochlea )-> cranial nerve VIII ( auditory )-> cochlear nucleus ( ventral / inferior )-> LLN-> caudal pontine reticular nucleus ( PnC ).

This has led to the suggestion that one cause of tinnitus might be a homeostatic response of central dorsal cochlear nucleus auditory neurons that makes them hyperactive in compensation to auditory input loss.
43.
The lateral lemniscus is a tract of axons in the brainstem that carries information about sound from the cochlear nucleus to various brainstem nuclei and ultimately the contralateral inferior colliculus of the midbrain.
44.
Afferent nerve fibres cross the midline from the cochlear nucleus to the cell bodies of the MOCS ( located near the MSOC ), whose efferent fibres project back to the cochlea ( red ).
45.
Models of hearing loss and the brain support the idea a homeostatic response of central dorsal cochlear nucleus neurons could result in them being hyperactive in a compensation process to the loss of hearing input.
46.
Data retrieved has shown that this targeting of the pyramidal cells modulates their activity and therefore plays a key role in the shaping of the overall output of the superficial layers of the dorsal cochlear nucleus.
47.
Acoustic stimulation of the inner hair cells sends a neural signal to the posteroventral cochlear nucleus ( PVCN ), and the axons of the neurons from the PVCN cross the brainstem to innervate the contralateral MOC neurons.
48.
The auditory brainstem electrodes were first implanted in humans in 1979 at the House Ear Institute, CA, USA . This original ABI consisted of two ball electrodes which were implanted near the surface of the cochlear nucleus.
49.
The fibers of the auditory nerve innervate both cochlear nuclei in the brainstem, the cochlear nucleus magnocellularis ( mammalian anteroventral cochlear nucleus ) and the cochlear nucleus angularis ( see figure; mammalian posteroventral and dorsal cochlear nuclei ).
