II. Hearing
... Inside the cochlea, there is a membrane (called the BASILAR membrane) covered in tiny HAIR CELLS. Amplified sound waves cause these to bend, which opens ion channels and sends a neural message to the thalamus via the auditory nerve. From there, the message is passed to the auditory cortex in the BRA ...

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.
