In experiments on three dogs there was shown that testing electrostimulation of the lateral hypothalamus reproduced the motor reaction which is a signal stimulus at elaboration of classic alimentary conditioned reflexes (CRs) and did not reproduce it at elaboration of classic defensive CR. Testing electrostimulation of medial parts of the hypothalamus reproduced, as LH electrostimulation the "signal" motor reaction, but in less percentage of cases, during elaboration of classic alimentary CRs and did not reproduce it at elaboration of classic defensive CRs. The reproduction of the signal motor reaction at LH electrostimulation is connected with activation of backward conditioned connection from motivation structures of the hypothalamus to representation of the signal stimulus in the motor cortex.
在对三只狗进行的实验中发现，对下丘脑外侧进行电刺激测试时，会重现一种运动反应，这种运动反应在经典食物性条件反射（CRs）形成过程中是一种信号刺激，而在经典防御性CRs形成过程中则不会重现。对下丘脑内侧部分进行电刺激测试时，如同对下丘脑外侧进行电刺激一样，会重现“信号”运动反应，但在经典食物性CRs形成过程中，出现这种情况的比例较低，而在经典防御性CRs形成过程中则不会重现。下丘脑外侧电刺激时信号运动反应的重现与从下丘脑的动机结构到运动皮层中信号刺激表征的逆向条件联系的激活有关。
