Cross-correlation histograms were plotted to study the linkage of spike activity in simultaneously recorded neurons in the central nucleus of the right and left amygdala in rabbits in calm waking, after 24 hours of food deprivation, in satiation, and in emotional tension (on presentation of dogs). Histograms showed peaks displaced from zero in 50-67% of cases. In hunger, many cases (52%) showed pairs in which the first neuron to discharge was in the left amygdala, this being followed by a neuron in the right amygdala (peaks from 10-50 and 130-150 msec). Firing in the opposite order was seen more rarely (36%). On presentation of dogs, there was an increase in the number of cases showing a common input to neurons, along with an increase in the leading role of neurons in the right amygdala (57%), due to increases in inhibitory influences from this area on cells in the left amygdala. The interaction of amygdalar neurons in these states was in most cases at frequencies in the delta range (74%), mainly at 2-4 Hz.
绘制互相关直方图，以研究家兔在平静清醒状态、禁食24小时后、饱腹状态以及情绪紧张状态（呈现狗时）下，同时记录的左右杏仁核中央核中神经元放电活动的联系。直方图显示，在50%-67%的情况下，峰值偏离零点。在饥饿状态下，许多情况（52%）显示，首先放电的神经元位于左侧杏仁核，随后是右侧杏仁核中的神经元（峰值出现在10-50毫秒和130-150毫秒）。相反顺序的放电则较少见（36%）。呈现狗时，显示神经元有共同输入的情况数量增加，同时右侧杏仁核中神经元的主导作用增强（57%），这是由于该区域对左侧杏仁核细胞的抑制作用增强。在这些状态下，杏仁核神经元之间的相互作用在大多数情况下处于δ波频率范围（74%），主要为2-4赫兹。
