Spatial Hearing
... Our ears give us much less information about object location than our eyes. We have only got two spatial channels for hearing (our two ears) compared to arguably several million for vision (the receptors in each retina). However, we can hear sound sources that are beyond our line of sight (e.g., beh ...

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.
