Descending projections from the inferior colliculus to medial olivocochlear efferents: Mice with normal hearing, early onset hearing loss, and congenital deafness
The IC sends tonotopic, glutamatergic projections to medial olivocochlear efferents. IC synapses to medial olivocochlear efferents are retained in hearing loss and deafness. IC projections to MOC efferents exhibit loss of precision with hearing loss and deafness.
