Re: Representation of auditory information at the cerebellar le

[Neil Todd <TODD@xxxxxxxxxxxxxxxxx>]

Dear 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.

rhythm and timing in music and speech. Proceedings of the International
Conference on Neural Information Processing.  ICONIP'98. Japan, October, 1998.

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.

Cheers
