Cross- and autocorrelation histograms were constructed to investigate the linkage of spike activity from neurons in the right and left lateral hypothalamus, recorded in conditions of restful waking, after 24-h food deprivation, and after satiation. In conditions of hunger, there was a preferred order in which neurons fired in these two hypothalamic regions: a significant majority of cases (59%) showed initial firing by a neuron in the left hypothalamus followed by a neuron in the right, with delays of up to 200 msec and peaks in the delay plot at 30 and 160 msec. The opposite firing order was seen less frequently (21% of cases). In conditions of hunger, linked spike activity showed an increase in the probability of detecting frequencies in the theta range (from 11% to 29%).
构建了交叉相关和自相关直方图，以研究在安静清醒状态、禁食24小时后以及饱足状态下记录的左右侧下丘脑神经元的峰电位活动之间的联系。在饥饿状态下，这两个下丘脑区域的神经元放电存在一个优先顺序：绝大多数情况（59%）显示左侧下丘脑的神经元先放电，随后右侧的神经元放电，延迟时间可达200毫秒，延迟图中的峰值出现在30毫秒和160毫秒。相反的放电顺序出现的频率较低（21%的情况）。在饥饿状态下，相关的峰电位活动显示检测到θ波范围内频率的概率增加（从11%增至29%）。
