Activity of Cortical and Dorsal Striatal Neurons in Animals in a “Right to Choose” Food Reinforcement Situation

摘要

Depending on the food-procuring strategy in a “right to choose” reinforcements with different food values, cats were classified as “self-controlled,” “ambivalent,” or “impulsive” on the basis of significant differences in the occurrence of different types of reflexes. The organization of interneuronal interactions in the frontal, visual, and motor areas of the cortex and the dorsal part of the caudate nucleus was evaluated during execution of short- and long-delay reflexes and errors. Similarities and differences in the organization of the network activity of neurons in different brain structures were studied in cats with different types of behavior. In “impulsive” and “self-controlled” animals, only neurons in the visual cortex and caudate nucleus showed similar functioning. Comparison of “impulsive” and “ambivalent” animals revealed similarity in the network activity of neurons in the visual and motor areas of the cortex and the caudate nucleus. Differences in the network activity of neurons in the frontal cortex were seen between animals of the three groups during execution of long-delay reflexes.
