Synopsis

Echolocating bats rely mainly on their biologicalsonar system to navigate and capture pray. Batsperceive direction, distance and identity of objectsin space by emitting brief ultrasound pulses andlistening to the echoes returned. By investigatingdirectional properties of the bat sonar system viaacoustic measurements of external ears and soundemission directivities this study revealsdirection-dependent acoustic cues that are availableto bats for localizing echo sources in space. It alsobrings out the necessity of the extra-auditoryinformation for the interpretation of the acousticspatial information. The book further focuses on howan organism could learn to localize sound sourceswithout any a priori neural representation of itsdirection-dependent acoustic cues or prior experiencewith auditory spatial information. A sensorimotormodel is proposed to address this question revealshow different aspects of sound localization, e.g.experience-dependent acquisition, adaptation, andextra-auditory influences, can be joined under acomprehensive framework for the first time.
