This project has pursued behavioral, physiological and anatomical correlates of the biosonar system of bats. We have used a simulated flight system to record signal emissions and to analyze the response properties of the ear and brain centers in animals actively engaged in the imaging of specific targets. Much new information has been obtained, especially with respect to the potential importance of interference patterns beats in biosonar signal detection and analysis. Computer reconstruction techniques have been used to study FFT displays and various anatomical structures. Keywords Acoustic signal perception and Bioacoustics.
