[The role of the emotiogenically negative brain structures in realizing an acid-defensive instrumental motor reaction].

In experiments in dogs it has been found that testing electrical stimulation of the lateral hypothalamus (duration of this stimulation--5-7 s), of the ventromedial hypothalamus and of the substantia grisea centralis of mesencephalon reproduced earlier elaborated acid-defensive instrumental conditioned reflex. This fact takes place due to the activation of the brain structures of negative emotion.
