The orderly innervation by auditory nerve fibers gives the AVCN a tonotopic organization along the dorsoventral axis. Fibers that carry information from the apex of the cochlea that are tuned to low frequencies contact neurons in the ventral part of the AVCN; those that carry information from the base of the cochlea that are tuned to high frequencies contact neurons in the dorsal part of the AVCN.
The AVCN's neural organization is characterized by a tonotopic arrangement along its dorsoventral axis. This means that different neurons are specialized to process specific frequency ranges, with those at the apex of the cochlea processing low frequencies and those at the base processing high frequencies.
