The processes of anticipation and evaluation of the results of behavior and their cellular neurochemical mechanisms.

The cellular neurochemical mechanisms of the goal-directed activity of cats under free behavior conditions were studied using the method of the microiontophoretic application of biologically active substances to individual neurons of the visual area of the cerebral cortex. Two experimental situations were used in the study. The first consisted of the alternation of the animal's instrumental reactions in the form of pedal-pressing with following reinforcement and of unexpected deliveries of milk in the food dispenser, and the second consisted of the alternation of the instrumental reactions with following reinforcement and of such reactions without reinforcement. An association was demonstrated of the cellular neurochemical mechanisms with the processes of the anticipation, perception, and evaluation of the results of the goal-directed activity.
