Subject: Re: Representation of auditory information at the cerebellar le From: Neil Todd <TODD(at)FS4.PSY.MAN.AC.UK> Date: Tue, 22 Jun 1999 16:44:36 GMTDear Eric There are several anatomical pathways of auditory information into the cerebellum. (1) To the cerebrocerebellum via the posterior parietal cortex (PPC), e.g. see Stein, J. "The posterior parietal cortex, the cerebellum and the visual guidance of movement". In F.W.Cody (Ed.) Neural control of skilled human movement. pp 31-49, 1995. (2) More direct inputs to the spinocerebellum, e.g. see Ghez, C. "The cerebellum" In Kandel et al (Eds). Principles of Neural Science. Appleton & Lange, Norwalk, CT. pp626-646. 1991. As for CASA, there is my own model of beat induction as auditoraly-guided action which follows Chris Miall (Miall, R.C., Weir, D.J., Wolpert, D.M. and Stein, J.F. "Is the cerebellum a Smith Predictor?" J. Mot. Behav. 25(3), 203-216, (1993).) in assuming that the cerebellum, at a functional level, acts as a kind of feedforward model. Todd, N.P. McAngus, Lee, C.S. and O'Boyle, D.J. (1998). A sensory-motor theory of rhythm and timing in music and speech. Proceedings of the International Conference on Neural Information Processing. ICONIP'98. Japan, October, 1998. Todd, N.P.McAngus, Lee, C.S. and O'Boyle, D.J. (1999) A sensory-motor theory of rhythm, time perception and beat induction. J. New Music Research. 28(1), 1-24. Todd, N.P.McAngus and Kohen, S. (submitted) Testing a sensory-motor theory of rhythm perception: Human vs machine performance in a tempo tracking task. Under review in Music Perception. Reciprocal connectivity to the PPC from the cerebellum may enable the perceptual system to be influenced by motor factors. Thus one prediction is that the way we 'hear' a rhythmic pattern is in part determined by the dynamic properties of the feedforward model, and hence the biomechanical properties of the musculoskeletal system. Todd, N.P.McAngus and Cousins, R. (submitted) Is beat induction mediated by an internal representation of the body? Evidence for a sensory-motor theory of rhythm perception. Under review in QJEP.
