Anatomy of The Olivocochlear System - Cell Bodies of Origin
... located medial to the MSO, gives rise to the medial olivocochlear system (MOCS) ... a distinct nucleus of neurons located lateral to the MSO, gives rise to the lateral olivocochlear system (LOCS) ... In addition to these classically defined olivocochlear neurons, advances in tract tracing methods helped reveal a third class of olivocochlear neurons, termed shell neurons, which ...

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 ...

Physiology of The Olivocochlear System - Neurophysiology
... All currently known activity of the olivocochlear system is via a nicotinic class neurotransmitter receptor complex that is coupled with a calcium-activat ... The olivocochlear synaptic terminals contain various neurotransmitters and neuroactive peptides ... The major neurotransmitter employed by the olivocochlear system is acetylcholine (ACh), although gamma-aminobutyric acid (GABA) is also localized in the terminals ...
