Multineuronal activity was studied in unrestrained cats with bundles of seven electrodes (tips dia. 50 mcm) chronically implanted in the auditory and motor cortex. Spikes of the highest and lowest amplitude were isolated from each neurogram by an amplitude discriminator. Functional connections between neurones located under different electrodes at a distance of up 540 mcm were defined by statistical dependence of the isolated spike series. In the auditory cortex, the distance at which it was possible to detect connections between high amplitude neurones (H-H) did not exceed 450 mcm, while between low amplitude neurones (L-L) it was 270 mcm. In the motor cortex, dependent relations for similar pairs of neurones (H-H) and (L-L) were found at all the studied distances up to 540 mcm. For mixed neuronal pairs (H-L and L-H) functional connections at different distances were differently expressed at various distances.
利用七电极束（尖端直径50微米）长期植入听觉和运动皮层的无束缚猫来研究多神经元活动。通过幅度鉴别器从每个神经图中分离出最高和最低幅度的尖峰。位于不同电极下方、距离达540微米的神经元之间的功能连接，由分离出的尖峰序列的统计相关性来确定。在听觉皮层中，能够检测到高幅度神经元（H-H）之间连接的距离不超过450微米，而低幅度神经元（L-L）之间的距离为270微米。在运动皮层中，在高达540微米的所有研究距离上，都发现了类似神经元对（H-H）和（L-L）之间的依赖关系。对于混合神经元对（H-L和L-H），不同距离处的功能连接在不同距离上有不同的表达。
