Dear Eli and List, There is no reason to assume that other mammals have different pitch mechanisms than humans. For humans we have now compelling data that exclude the view that pitch is first extracted in the auditory cortex: Fishman YI, Volkov IO, Noh MD, Garell PC, Bakken H, Arezzo JC, Howard MA, Steinschneider M (2001) Consonance and dissonance of musical chords: neural correlates in auditory cortex of monkeys and humans. J Neurophysiol 86:2761-88. The authors did not discuss the location of pitch extraction in this paper. They focused on the consonance issue. But in seven of their figures the data show that pitch of harmonic complex tones must be extracted below the primary auditory cortex. I pointed this out in a comment about the paper on my website, for which Yon Fishman was very grateful: Martin ------------------------------------------- Martin Braun Neuroscience of Music S-671 95 Klässbol Sweden e-mail: nombraun(at) web site:
