Subject: Re: HC selectivity ... was Re: Physiological models of cochlea activity - alternatives to the travelling wave From: Martin Braun <nombraun@xxxxxxxx> Date: Fri, 28 Sep 2007 14:14:28 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Hi Matt and others, Our job is not to find mathematical equations that fit our thoughts. Our job is to look at real biological systems and to try to understand them. > I can not see the link between CF-tuned hair cells and cochlea amplification - currently ... the hair cells need to actuate some form of mechanical model ... right ? No, sorry. Not right. The hair cells need not "actuate" any model that is in anybody's head. The hair cells are there, and they do their job successfully. There is a vast amount of literature on hair cell tuning. It is our job to look at all the data and see what these cells do. It's not our job to fit some selected data to the models in our heads. Just a few papers for a start: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1193795 http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=9265753&ordinalpos=24&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=15102898&ordinalpos=6&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=15925861&ordinalpos=3&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum http://www.ncbi.nlm.nih.gov/sites/entrez?Db=pubmed&Cmd=ShowDetailView&TermToSearch=16307854&ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum Martin --------------------------------------------------------------------- Martin Braun Neuroscience of Music S-671 95 Klässbol Sweden web site: http://w1.570.telia.com/~u57011259/index.htm
