The effect of an increment in the power of the rhythmic activity of the amygdala during changes in the level of motivation in conditions of the dominance of alimentary or defensive motivation, irrespective of type, was discovered on the basis of spectral analysis of prolonged recordings of electrosubcorticograms of the amygdaloid complexes of three dogs. The resonance characteristics of the system responsible for the generation of this rhythm remain unchanged in the process, which allows explanation of the increase in the spectral peak by an increase in the inflow of afferent impulse activity into the amygdala. Summation of the influences of each of them is not observed in the presence of competing motivations, while a more complex influence on rhythm in the amygdala emerges.
基于对三只狗杏仁核复合体的皮质下电图进行长时间记录的频谱分析,发现了在以食物或防御动机为主导的条件下,无论动机类型如何,当动机水平发生变化时杏仁核节律性活动功率增加的效应。在此过程中,负责产生这种节律的系统的共振特性保持不变,这使得可以通过传入冲动活动流入杏仁核的增加来解释频谱峰值的增加。在存在相互竞争的动机时,未观察到它们各自影响的总和,而对杏仁核节律产生了更复杂的影响。
