Cross-correlation analysis of interdependence of the background spike activity was carried out for pairs of adjacent neurons simultaneously recorded in the incubated slices of the neocortex of guinea-pig. Statistical correlation of spike discharges was detected in 16 out of 26 recorded pairs of the neurons. Significant correlation was observed mainly in the range of +/- 100 ms from the null point. Cross-correlation had symmetric or asymmetric maxima up to 150 ms long and negative shifts up to 200 ms long. More complex positive-negative types of cross-correlations were also obtained. The data were compared to those known from other authors for the intact brain. The contribution of intrinsic intracortical interactions and extrinsic afferent influences in these correlations of activity is discussed.
对豚鼠新皮层孵育切片中同时记录的相邻神经元对的背景峰电位活动的相互依赖性进行了互相关分析。在记录的26对神经元中的16对中检测到了峰电位发放的统计相关性。主要在距零点±100毫秒范围内观察到显著相关性。互相关具有长达150毫秒的对称或不对称最大值以及长达200毫秒的负向偏移。还获得了更复杂的正负型互相关。将这些数据与其他作者关于完整大脑的数据进行了比较。讨论了这些活动相关性中内在皮质内相互作用和外在传入影响的作用。
