ABSTRACT

RNA-synthesizing activity of neuronal nuclei in the neocortex of rats increases after the termination of conditioning depending on the degree of learning. RNA synthesis shifts induced by propylnorantifein and the demethylated derivatives of ethylnorantifein are correlated only with the influence of the drugs on the retention but not the learning. Participation of RNA synthesis by the neurons of the neocortex in the mechanisms of long-term memory is discussed.
