Short description of important scientific result: It is shown that besides the well known role of serotonin as a mediator in the synaptic transmission, it can perform integrative functions during learning. It was found experimentally that daily injections of serotonin and its synthesis precursor 5-hydroxytryptophan (5-HTP) before the training session can accelerate the generation of conditional defensive reflex, and injection of 5-HTP on the background of deficiency of serotonin created by the neurotoxin, returned the ability of animals to learn.
