| Abstract: | Systemic administration of the specific antagonists of D1 (SCH23390, 0.005-0.1 mg/kg) and D2/D3 (raclopride, 0.1-0.25 mg/kg) dopamine receptors leeds to dose-dependent increase of the reaction time and decrease of conditined reflex probability up to full blocking (in the case of SCH23390) of alimentary and escape conditioned placing reaction in cats. The action of both antagonists was far more suppressive regarding conditioned escape reflex. The action of SCH23390 was far more effective than that of raclopride concerning both types of conditioned reflexes. |
