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.
在对两只狗进行的实验中发现，对下丘脑外侧进行测试性电刺激，在已形成对音调的食物性工具性条件反射的情况下会重现工具性动作，而在已形成酸性防御性工具性条件反射的情况下则不会重现。在对下丘脑内侧进行电刺激时，无论是在食物性还是防御性情境中，工具性动作基本上都不会重现。在食物性情境中，对下丘脑外侧进行电刺激时工具性动作的出现与从下丘脑的动机性“食物”中心到运动皮层中该动作表征的逆向条件性联系的激活有关。
