NEUROPHYSIOLOGICAL CORRELATES OF ECHOLOCATION IN BATS.

Abstract

Bats of the suborder Microchiroptera exhibit skills in the use of sound for orientation that are equalled in no other mammals. Some of these skills are described, with a discussion of the problems these uses of sound must pose for the auditory nervous system. After a brief comparison of the morphology of auditory structures in bats and other mammals, the main body of the thesis presents the results of electrophysiological recordings from the auditory nervous systems of two Vespertilionids, Myotis l. lucifugus and Plecotus townsendii. These recordings provide several evidences of neural specialization for the particular requirements of echolocation. (Author)
