Adaptive vocal behavior drives perception by echolocation in bats

Curr Opin Neurobiol. 2011 Aug;21(4):645-52. doi: 10.1016/j.conb.2011.05.028. Epub 2011 Jun 24.

Abstract

Echolocation operates through adaptive sensorimotor systems that collectively enable the bat to localize and track sonar objects as it flies. The features of sonar signals used by a bat to probe its surroundings determine the information available to its acoustic imaging system. In turn, the bat's perception of a complex scene guides its active adjustments in the features of subsequent sonar vocalizations. Here, we propose that the bat's active vocal-motor behaviors play directly into its representation of a dynamic auditory scene.
