A study was made of the influence of ablation of the entorhinal cortex on conditioned reflexes to present and trace stimuli. Ablation resulted in a long-lasting and considerable disturbance of differentiation of time macrointervals. After the operation, elaboration or restoration of the conditioned reflex to time was delayed five or six times as compared… (More)
The paper shows the dependence of behavioral changes provoked by corazol on individual characteristics of the animals. The rats with high activity in the ATS demonstrated the highest response to the drugs.
Upon stimulation and blockade of dopaminergic system of rats in the shuttle box the correlation between the strategy of escape behavior and functional state of dopaminergic system has been found. The modulatory effect of these systems on the mechanism of the adequate choice is suggested.
The free behaviour experiments on rats showed during the first day the tuftsin-induced (0.3 mg/kg i. p.) increment of epileptic discharge in all the structures simultaneously. Open field behaviour depended on the sequence of penicillin and tuftsin injections. The rats with tuftsin used after the epileptiformic activity has been developed showed the… (More)
