Characteristics were studied in the same dogs of the formation of conditioned reflexes to signals reinforced by biologically different stimuli--food, acid and current and of differentiations to them, after amygdala ablation. Amygdalectomy leads to the disturbance of the conditioning process, independently of the biological significance of the reinforcement. However, the deepest and the most prolonged disturbances occur in the system of alimentary behaviour and in elaboration of more complicated instrumental defensive reflexes in which current avoidance requires not only lifting of the paw but also retaining at a definite height for a certain time. Amygdala ablation considerably impedes the process of differentiation of positive and inhibitory stimuli leading to a disturbance of correct evaluation of signal significance and to inadequate behavioural reactions.
在杏仁核切除术后，研究了同一批狗对由生物学上不同的刺激——食物、酸和电流强化的信号形成条件反射以及对它们进行分化的特征。杏仁核切除术会导致条件反射过程的紊乱，而与强化的生物学意义无关。然而，最深刻和最持久的紊乱发生在进食行为系统以及更复杂的工具性防御反射的形成过程中，在这种反射中，电流回避不仅需要抬起爪子，还需要在一定高度保持一定时间。杏仁核切除极大地阻碍了阳性和抑制性刺激的分化过程，导致对信号意义的正确评估受到干扰以及行为反应不充分。
