The preservation of the effect of dynamic scanning of a part of the orientation diapason during development of neuron responses in the primary visual cortex of cat was examined after equalization of their latencies and after estimation of only highly significant fragments of their reactions. It was found that this effect was preserved in 13 neurons out of 17 examined ones: it remained invariable in 7 units of this group and was modified due to a shift of the scanning beginning along the diapason of orientations, to an increase of scanning diapason or to a change of scanning direction. The stabilization of the orientational tuning occurred only in 4 cells after equalization of latencies. The obtained results confirm that the dynamic changes of orientation tuning in the majority of visual cortex neurons are connected with reorganization of the time pattern of the reaction, as suggested by the hypothesis of the spatial-temporal orientation coding in the visual system.
在猫的初级视觉皮层神经元反应发育过程中，当对其潜伏期进行均衡处理并仅评估其反应中高度显著的片段后，对一部分方向范围进行动态扫描的效果的保存情况进行了研究。结果发现，在所检查的17个神经元中，有13个神经元保留了这种效果：该组中的7个单位保持不变，另外一些则由于扫描起始点沿方向范围的移动、扫描范围的增加或扫描方向的改变而发生了变化。在潜伏期均衡后，只有4个细胞出现了方向调谐的稳定。所获得的结果证实，正如视觉系统中时空方向编码假说所表明的那样，大多数视觉皮层神经元方向调谐的动态变化与反应时间模式的重组有关。
