Re: Representation of auditory information at the cerebellar level?
Another feature of Cerebellum computation is Coordinate Transformation.
I have no direct evidence for the following conclusion but, I strongly suspect
that directional hearing is transformed to Acoustic Environment prediction
in the Cerebellum, i.e., acoustic estimate of room surface positions and
source locations. Whether (or not) these calculations are cerebellar
at least fits cerebellar neural architecture but, my work supports
(Law of Cosines) needs to iteratively (calculate) map acoustic environments
from delay and arrival angle estimates.
