Subject: Re: Function of Cochlear Nucleus cell types From: "Richard F. Lyon" <dicklyon@xxxxxxxx> Date: Mon, 6 Jan 2014 15:02:20 -0800 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--001a11c37f187fd8c704ef5540b2 Content-Type: text/plain; charset=ISO-8859-1 That's an interesting question, too, Randy, but likely not very related to cochlear nucleus. I've gotten a few pointers so far, and requests to share the results. I'll do that.
