Subject: Re: Most apical inner hair cell From: Eric LePage <ericlepage@xxxxxxxx> Date: Wed, 6 Feb 2008 11:47:35 +0900 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hi Robert, I'm not aware of anything specifically on the human morphology but the various primate labs might have addressed this question, e.g http://www.hei.org/research/scientists/flinthicum.html I suggest your perspective might be broadened if look for papers on maturation and development specifically by authors Fekete and also Brigande, also Echteler as these address the development of the spiral; e.g. whether it simply zooms up in size or whether the apical end extends (telescopes) during development and when that process ceases. It certainly seems to be the case that this termination process may be quite variable, somewhat on gender and if course strongly upon species. When I started to think about what defines the apex a few years back I found much food for thought. So you might also consider my article which addresses the idea of redefining the apex in relation to the Greenwood map model and a variety of logical consequences flowing from this hypothesis: LePage, E. L. (2003). The mammalian cochlear map is optimally warped. J. Acoust.Soc.Am. 114(2), 896-906.
