Role of the lateral and medial hypothalamus in the reproduction of alimentary and defensive instrumental reactions

Abstract

It was established in experiments on two dogs that a test electrical stimulation of the lateral hypothalamus reproduces an instrumental movement in the case of a developed alimentary instrumental CR to a tone and does not reproduce it in the case of a developed acid defensive instrumental CR. In the case of an electrical stimulation of the medial hypothalamus, the instrumental movement is essentially not reproduced, either in the alimentary or the defensive situations. The appearance of the instrumental movement with electro-stimulation of the LH in the alimentary situation is associated with activation of the backward conditioned connection from the motivational “alimentary” center of the LH to the representation of this movement in the motor cortex.
