[Effect of insulin and its polymeric analogs on learning and memory processes in the rabbit]

The effect of insulin and its seven synthetic derivatives on spontaneous bioelectrical activity of the cerebral cortex of rabbits was described in the paper. The influence of these substances on consolidation of long-term memory of white rats was shown at normal state and during experimental neurosis. Insulin was supposed to influence the higher nervous activity not only through glucose metabolism but also by means of increase of permeability of biological membranes for amino acids.
