Final Report for Oregon University Grant N00014-89-J-1582.
Abstract
The overall goal of this project was to investigate the perception of moving sound sources by the auditory system of barn owl (Tyto alba). Although moving sound sources are abundant in the environment, there are surprisingly few studies on acoustic motion perception in species that do not use active echo- location. The barn owl is a keen auditory predator that can capture moving prey in absolute darkness using only passive hearing (Payne, 1971). It therefore served as the model system in which to analyze acoustic motion perception. Using behavior, neurophysiology, and computer-modelling we addressed two large issues: (1) How is velocity, ie, speed and direction, coded in the auditory system? (2) What role does motion play in auditory perception and acoustically-guided behavior?
