Subject: Re: propagation speed of the traveling wave From: David Mountain <dcm(at)BU.EDU> Date: Fri, 8 Apr 2005 09:42:39 -0400I would recommend a pair of papers that just came out from Mario Ruggero's lab:: Recio-Spinoso A, Temchin AN, van Dijk P, Fan YH, Ruggero MA. Wiener-kernel analysis of responses to noise of chinchilla auditory-nerve fibers. J Neurophysiol. 2005 Jan 19; [Epub ahead of print] PMID: 15659532 Temchin AN, Recio-Spinoso A, van Dijk P, Ruggero MA. Wiener kernels of chinchilla auditory-nerve fibers: verification using responses to tones, clicks and noise and comparison with basilar-membrane vibrations.
