An Update on Auditory Neuropathy Spectrum Disorder in Children

The term “auditory neuropathy” was coined in the mid-1990’s to describe a form of hearing impairment in which cochlear (outer hair cell) function appeared normal, but afferent neural activity in the VIIIth nerve and brainstem was disordered (Starr, Picton, Sininger, Hood, Berlin, 1996). However, the ...

Olivocochlear system
The olivocochlear system is a component of the auditory system involved with the descending control of the cochlea. Its nerve fibres, the olivocochlear bundle (OCB), form part of the vestibulocochlear nerve (VIIIth cranial nerve, also known as the auditory-vestibular nerve), and project from the superior olivary complex in the brainstem (pons) to the cochlea.
