An assessment of spectral analysis of amphetamine-induced behavior

Testing of a new radio frequency capacitance field type transducer and power spectrum analysis system for assessment of rat behavior is described. Power spectrum estimates of amphetamine-induced behavior had an orderly relationship with behavior ratings ranging from inactive to intense stereotypy. The effects of thorazine dose-response blocking on amphetamine-induced behavior were linear. Separation between adjacent doses could not be accomplished with a single frequency, but required differential frequency-time period information.
