Multipolar cells in the ventral cochlear nucleus project to the dorsal cochlear nucleus and the inferior colliculus.
When retrograde markers are placed in the dorsal cochlear nucleus two classes of labeled cells are found in the ventral cochlear nucleus. These are multipolar cells and granule cells. The structure and distribution of labeled multipolar cells greatly resemble those seen following injection of retrograde markers into the contralateral inferior colliculus. When one retrograde marker is placed in the dorsal cochlear nucleus and another simultaneously placed into the contralateral inferior colliculus, large numbers of multipolar cells containing both markers are found in the ventral cochlear nucleus. These findings show that all or most cells in the ventral cochlear nucleus that project to the inferior colliculus also send collaterals to the ipsilateral dorsal cochlear nucleus.
