Reaction of sensorimotor cortex neurons to stimulation of the lateral hypothalamus in conditions of microiontophoretic application of tetragastrin and bradykinin: the role of food reinforcement.

Experimental data were obtained on the nature of rabbit sensorimotor cortex neuron reactions to stimulation of the food motivation center of the lateral hypothalamus in conditions in which food was or was not presented to the animals combined with microiontophoretic application of tetragastrin and bradykinin. These neuropeptides were able to alter the relationship between motivation and reinforcement.
