[A general biological hypothesis on the mechanisms of the effect of different psychotropic agents that optimize memory].

Possibility of interpretation of the effects of psychotropic drugs on memory is considered from the viewpoint of general biological conception on molecular mechanisms of memory. Previous studies of functional-molecular mechanisms of memory in animals at different evolutionary levels, carried out by the author and collaborates, became a theoretical basis of the hypothesis proposed. In particular, genome modification was established to be induced by learning and specific and universal components of memory were revealed. Possibility of genome activation in the brain is considered as one of deciding factors in the mechanism of memory optimization by psychotropic drugs.
