Using pigeons we study how simple or complex sounds, ranging from infrasound to higher frequencies are processed in the brain. We are also interested in the sound localization (and auditory "figure/ground" segregation) abilities of birds and mammals, and use owls and rats for these experiments. Our experiments are conducted in an anechoic chamber equiped with a moveable speaker array. A customized auditory program running on our IBM computer allows us to produce white noise, various tones, from infrasound to higher frequencies, and complex sounds including species specific vocalizations. The auditory program also analyzes the data obtained from the various auditory neurons.
