I recently heard a talk by Shihab Shamma on the work his lab at the
University of Maryland has been doing with ferrets. They found
primary auditory cortex cells with preferential response to various
frequency change rates and directions, and various bandwidths. The
abstract is here:

And a technical report is here:

Hope that helps,
