Experiments in male albino rats have shown that bilateral lesion of the amygdala does not prevent avoidance conditioning to pain stimulation of another rat, improvement of the reaction after a painful action of the experimental animal and its extinction after the discontinuation of pain stimulation of the partner. Amygdalectomy performed after elaboration of a conditioned avoidance reaction, improves or worsens it, depending on which of the two rivaling motivations (sensitivity to signals of the other animal or fear of an open field) relatively predominanted in the given animal before the operation. The facts obtained suggest that the amygdala may be classified as belonging to the system of brain structures, where the "interrupting function" of emotions is achieved directing the behaviour to meet the predominant need. |
