Re: Representation of auditory information at the cerebellar le
There are several anatomical pathways of auditory information into the
(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
(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

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
