Subject: Re: cochlear nucleus : Higher level then the audio periphery From: David Mountain <dcm(at)BU.EDU> Date: Fri, 20 Sep 2002 08:49:48 -0400There is a cochlear nucleus on both sides of the brain stem and the cochlear nucleus is made up of several subdivisions that appear to be specialized to process different types of information. The cochlear nuclei receive their major input from the auditory nerve but they also receive input from their partner on the opposite side and they also receive input from higher auditory structures and from the somatosensory system. The cochlear efferents do not originate in the cochlear nucleus, but rather from the superior olivary complex. If you would like to learn more about the details of these systems, I would recommend reading: "Integrative Functions in The Mammalian Auditory Pathway." Oertel D, Fay RR, Popper AN Eds.
