[DOPAMINE STIMULATION AFFECTS MULTIPLE - FOOD - UNIT PREFERENCE IN RATS].

Abstract

It has been shown that food seeking behavior in rats performing in different types of mazes is controlled by discrete reward pattern related to change in attractive properties of reinforcement and dopamine activity plays a critical role in motivation and food preference processing. The data obtained suggest that behavior as well as amphetamine effects revealed under the exposition of the discrete reward paradigm of learning may be involved in a common mechanism underlying food disorders and drug addiction in humans.
