title: [The interaction of a state of haloperidol-induced catalepsy and a passive-avoidance conditioned reflex].
abstract: Injection of haloperidol (2.5 mg/kg) immediately after elaboration of the passive avoidance conditioned reflex stabilized retrieval of the conditioned reflex on the 2nd, 7th, and 14th days. Catalepsy induced by haloperidol injection was increased after the completion of passive avoidance conditioning. Conditioned reflex retrieval decreased catalepsy which was retrieved without repeated haloperidol injection. In contrast to the control animals, in the animals after conditioning the most pronounced catalepsy was observed immediately after the conditioned reflex retrieval with the following stabilization at the lower level. The auto enhancement of catalepsy retrieval was more expressed on the 14th day (as compared with the 7th day) both in the control and learned animals, but in the latter it did not depend on the testing time (in contrast to the control animals.
