Abstract

Multipolar cells in cochlear nucleus have been shown to be contacted by medial olivocochlear (MOC) collaterals. However,
controversy exists regarding which multipolar (Tor D-stellate) cells are the specific targets. This project aimed to elucidate
this controversy by both retrograde and anterograde tracer studies in both guinea pigs and rats. However, very few putative
synaptic contacts were found between MOC collaterals and either of the T and D-stellate cells, though numerous contacts were
observed with unlabelled structures. Further research is required to identify these unlabelled structures in order to establish
which cochlear nucleus cells are innervated by MOC collaterals.
