[Effect of phenamine and caffeine on the behavioral changes occurring after the cessation of caudate nucleus electric stimulation in cats]

Abstract

Low doses of amphetamine (0.1-0.5 mg/kg), not influencing the spontaneous behaviour of cats, prevent behavioral depression arising after repeated low-frequency stimulation of the caudate nucleus. Activating phenomena, observed after cessation of the stimulation, are considerably intensified up to the stereotypy formation. Caffeine (10-80 mg/kg), when activating spontaneous behaviour in cats, does not exclude a possibility of caudate-induced depression.
