--001a11c3407ccaf86804ef82f5db Content-Type: text/plain; charset=ISO-8859-1 On CN function, the best publications people suggested are: 1. Rhode, William S., and Steven Greenberg. "Physiology of the cochlear nuclei."*The mammalian auditory pathway: Neurophysiology* 2 (1992): 94-152. - http://web.mit.edu/hst.723/www/ThemePapers/CochlearNucleus/Rhode92.pdf 2. Cochlear Nucleus, Eric D Young And Donata Oertel - http://web1.johnshopkins.edu/chb/research/CNSOB.pdf or http://books.google.com/books?id=KBkR8PwU6ewC&pg=PA125 chapter 4 in The Synaptic Organization of the Brain, edited by Gordon M. Shepherd, 5th ed. 2003 3. Wang, Huan, et al. "Auditory information coding by modeled cochlear nucleus neurons." *Journal of computational neuroscience* 30.3 (2011): 529-542. (author Werner Hemmert sent me a copy) several on DCN discrimination of head-related transfer functions (HRTFs), spectral cues used for vertical sound localization. There's a lot more on this topic: 4. Reiss, Lina AJ, and Eric D. Young. "Spectral edge sensitivity in neural circuits of the dorsal cochlear nucleus." *The Journal of neuroscience* 25.14 (2005): 3680-3691. - http://www.jneurosci.org/content/25/14/3680.long 5. May, Bradford J. "Role of the dorsal cochlear nucleus in the sound localization behavior of cats." *Hearing research* 148.1 (2000): 74-87. - http://stuff.mit.edu/afs/athena/course/other/hst.722/OldFiles/www/Topics/DCN/May2000.pdf What's clear is that different cell types in DCN and VCN make several parallel differently processed representations. Getting more specific, there's good info on binaural and monaural localization processing, some on spectral, temporal, and envelope enhancement, etc., but in general it seems to remain rather vague (to me); but I haven't finished reading, so maybe it will get more clear. Several people also shared a bit on not-yet-published ideas; hopefully they'll let us know when the time is right. Dick On Mon, Jan 6, 2014 at 3:02 PM, Richard F.
