[Neuropharmacologic analysis of the process of generalization in the cat].

Processes of generalization and abstraction were studied in intact cats before and after systemic administration of dopamine-, cholin- and GABA-ergic substances in conditions of free behaviour with food reinforcement by a developed method. It is shown that only inhibition or activation of dopaminergic system disturbs the function of generalization in animals. Some possible neurochemical mechanisms of generalization in animals are being analyzed.
