Neurobiology of Binaural Hearing
Office Phone: (608) 262-0368
My general area of interest is in studying how sensory signals are transformed into motor output in the mammalian central nervous system. My approach is to couple electrophysiological methods with anatomical or behavioral methods, when appropriate. Work is now directed primarily at studying the neural mechanisms of sound localization and other binaural phenomena. Experiments involve recording from single cells in anesthetized cats using dichotic and free-field acoustic stimuli. In some experiments neurons are injected intracellularly to permit morphological studies. Most experiments use stimuli that are designed to mimic psychophysical phenomena, such as the precedence effect. In addition, we train cats to look at sounds by monitoring their eye movements to study the psychophysics of sound localization in the cat as well as to make chronic electrophysiological recordings while the cat is actively engaged in the task. When possible, neuronal responses are simulated on computer models of the circuits.
