Direct projections from the dorsal column nuclei and the spinal trigeminal nuclei to the cochlear nuclei in the cat

A retrograde and anterograde wheat germ agglutinated horseradish peroxidase WGA-HRP study in the cat indicated that some neurons in the dorsal column nuclei and the interpolar and caudal spinal trigeminal nuclei send fibers to the dorsal and ventral cochlear nuclei; to the pyramidal cell layer of the dorsal cochlear nucleus and to the cochlear granule cell domain, bilaterally with an ipsilateral dominance.
