ACTION OF SEROTONERGIC SYSTEM IN THE 2-ST AGE PROCESS OF FORMATION OFLATENT INHIBITION IN RATS

Activation of rat brain serotonergic system (injections of a selective serotonin reuptake blocker sertralin) at the stage of preexposition o f the situation stimulus (placing into the illuminated compartment of the dark-light shuttle-box) intensified subsequent development of the latent inhibition at the stage of conditioning, which was measured by the latent period of transition to the dark compartment during the fir st testing after reinforcement of such transition with electrical shoc k.
