Lesions of the amygdala in cats and dogs prevent some animals to respond adequately to signals of different biological significance; the amplitudes and probabilities of EPs appearance in the sensomotor cortex lose their maximums at 0.8 and 1.6 frequencies within the range of 2.0 to 3.0 kHz which are formant ones of some communication signals in cats. Rendering an indifferent stimulus a signal, i. e. food significance, becomes reflected in the amygdala neuronal activity, the amygdala starting to respond to the signal as if it were an unconditioned stimulus. The data obtained are used to discuss the role of amygdala in assessment of conditioned stimuli biological significance as well as in differentiation of incoming afferent influences.
猫和狗的杏仁核损伤会使一些动物无法对具有不同生物学意义的信号做出充分反应；在2.0至3.0千赫兹范围内，感觉运动皮层中诱发电位出现的幅度和概率在0.8和1.6频率时失去最大值，而该频率范围是猫的一些交流信号的共振峰频率。将一个中性刺激赋予信号意义，即食物意义，会反映在杏仁核神经元活动中，杏仁核开始像对非条件刺激一样对该信号做出反应。所得数据用于讨论杏仁核在评估条件刺激生物学意义以及区分传入的传入影响中的作用。
