An analysis of central afferent projections to the dorsal cochlear nucleus (dCo), one of the three target nuclei of the auditory nerve, was made using retrograde axonal tracer, wheat germ agglutinin-horseradish peroxidase (WGA-HRP) in the rabbit. The findings showed that, in addition to its afferents from the brainstem auditory nuclei (they are not described herein), the dCo received sparse bilateral connections from the caudal three quarters of the vestibular nuclear complex (VNC). Following selective iontophoretic injections of WGA-HRP into the dCo, a small number of labelled neurones (from 2 to 28 per case) was found in the rostral and caudal portions of the medial vestibular nucleus and in the inferior vestibular nucleus. These neurones were observed mainly in the lateral regions of the nuclei. No labelling appeared in other nuclei which belonged to the VNC. The secondary vestibulocochlear connections have not been reported before in any species. With the anatomical method used, however, their functional role is difficult to explain. Further study is necessary to identify the type of neurotransmitter as well as the physiological properties of vestibular neurones projecting to the dCo, in terms of their responses to a change of the head position and to sound.
