The purpose of this study was to ascertain those brain systems directly associated with inhibition of motor activity. Chronic cats with implanted electrodes were operantly conditioned for an absence of phasic motor activity. Peripherally and centrally evoked responses are obtained from the implanted electrodes during movement, non-movement, and sleep periods. All electrode sites are verified using histological techniques. Standard computer signal averaging techniques are used in the data analysis. Amplitude changes of evoked responses from various brain structures will be compared between movement, non-movement, and sleep stakes. As the data collection phase is still in progress, no results are presently available. Interpretation of the results will be made according to the structural and functional organization of those brain areas showing significant alterations during the behavioral conditions of this study.
