Abstract : Complex sounds describe most of the sounds that are perceived in our everyday life. However, most of our present knowledge is required about the neural process studying simple sounds. More knowledge is required about the neural processing of complex signals and about how animals process similar complex sounds. This proposal was to purchase two real-time, high-speed data acquisition computers similar to the one used for the human perception research at the Parmly Hearing Institute. These computers, MASSCOMPs, will be used to generate stimuli and to analyze behavioral and neurophysiological response. The research in these projects involves the human perception of complex stimuli, and combined animal behavior and neurophysiological measures of some of these stimuli, and combined animal behavior and neurophysiological measures of some of these stimuli. The physiological studies include measurements within the eighth nerve and at the level of the cochlear nucleus of the auditory system. In order to relate these measures to the animal's ability to process these stimuli a series of animal behavioral studies are described. The addition of these computer was essential for the full benefit of a multidisciplinary study of the processing of complex sounds. Keywords: Complex sound processing, Hearing, Psychophysics, Physiology.
