Functional organization of auditory corticofugal circuits.

In the auditory system, function often directly follows form. Segregation of cell types in the organ of Corti and cochlear nucleus has revealed fundamental lessons about the biology of hearing. However, no such understanding exists at the level of the auditory cortex. By disambiguating the roles of distinct classes of projection neurons, our research program aims to understand the principles of cortical organization, and how such principles can give rise to complex behaviors.
