Histologic Analysis of Chronos in an
... No histologic studies have yet examined the virally-mediated gene transfer of Chronos, a new opsin, to the murine cochlear nucleus (CN). Herein, we aim to 1) identify CN regions and neurons receptive to gene transfer of Chronos and 2) describe the morphology of putative cell types that express Chron ...

This demonstrates the perceptual heuristic that sounds with the same frequency come from the same source, which is usually true in 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.
