How Biosonar Information is Represented in the Bat Cerebral Cortex

In mammals, an auditory signal sent to the brain by the cochlear nerve ascends from the cochlear nucleus to the auditory cortex of the cerebrum through many intermediate nuclei. The auditory signal is projected in parallel to each level of the central auditory system, because of multiple projections from the cochlea. This multiple projection suggests that different types of auditory information or different attributes of the signals are processed both hierarchically and in parallel. Except for the auditory cortex of the mustached bat, Pteronotus parnellii rubiginosus***, however, little is known about how this multiple representation is related to functional organization beyond frequency representation.
