Spike activity was simultaneously recorded from pairs of units consisting of both optic tract fibers and relay cells in the cat dLGN. The unit pairs were classified with regard to the types of receptive fields involved, the relative location of receptive fields, and their occular drive. Statistical dependencies between the discharge patterns of the simultaneously observed units were assessed by computing their auto- and crosscorrelogram during a period of maintained discharge. Two distinctly different types of statistical dependence were observed. Unit pairs having like and overlapping receptive field centers exhibited statistical dependencies manifested in their crosscorrelograms by a peak near the origin. Conversely, unit pairs having opposite and overlapping receptive field centers were characterized by a prominent valley in their crosscorrelograms near the origin. These statistical dependencies are inferred to represent functional interaction most probably occurring in the retina and characterized by a common element exerting an influence on both units.
在猫的背外侧膝状体（dLGN）中，同时记录了由视束纤维和中继细胞组成的成对神经元的锋电位活动。根据所涉及的感受野类型、感受野的相对位置及其眼动驱动，对神经元对进行了分类。通过计算在持续放电期间的自相关图和互相关图，评估了同时观察到的神经元放电模式之间的统计依赖性。观察到两种明显不同类型的统计依赖性。具有相似且重叠感受野中心的神经元对表现出统计依赖性，其互相关图在原点附近有一个峰值。相反，具有相反且重叠感受野中心的神经元对在其互相关图的原点附近有一个明显的谷值。推断这些统计依赖性代表了最有可能发生在视网膜中的功能相互作用，其特征是一个共同元素对两个神经元都有影响。
