title: Descending inputs to caudal cochlear nucleus in cats: a horseradish peroxidase (HRP) study.
abstract: After HRP injections into the octopus cell area of the cat cochlear nucleus, only periolivary neurons of the superior olivary complex (SOC) reacted. Elongate neurons in the lateral periolivary nuclei (ipsilateral to the injection) and multipolar neurons in ventromedial periolivary regions (contralateral to the injection) contained granules. No neurons in the main SOC nuclei or higher auditory nuclei reacted, despite a wide range of HRP concentrations. Thus, neurons from the SOC to the octopus cell area of the cochlear nucleus seem to be entirely periolivary and not entirely equivalent to neurons providing collaterals to the olivocochlear bundle.
