[The neuronal reaction of the sensorimotor cortex to stimulation of the lateral hypothalamus with a background of the microiontophoretic administration of tetragastrin and bradykinin: the role of food reinforcement].

[Article in Russian]


Reactions of neurons of sensorimotor cortex to stimulation of the "center of hunger" in the lateral hypothalamus were studied at the background of microiontophoretic application of gastrin, and bradikinin in satiated freely behaving rabbits under conditions of presence or absence of free access to food. It was shown that food reinforcement essentially changed reactions of neurons to electrical stimulation of the lateral hypothalamus at the background of application of neuropeptides under study. This probably led to specific reorganization in the neuronal system which underlay the mechanism of interaction between motivation and reinforcement influences on the neurons.
