We propose a model for the lateral connectivity of orientation-selective cells in the visual cortex. We study the properties of the input signal to the visual cortex and find new statistical structures that have not been processed in the retino-geniculate pathway. Using the idea that the system performs redundancy reduction of the incoming signals, we derive the lateral connectivity that will achieve this for a set of orientation-selective local circuits, as well as the complete spatial structure of a network composed of such circuits. We compare the results with various physiological measurements.
我们提出了一种视觉皮层中方向选择性细胞侧向连接的模型。我们研究了输入到视觉皮层的信号特性，并发现了在视网膜 - 膝状体通路中未被处理的新统计结构。利用该系统对传入信号进行冗余减少的观点，我们推导出了一组方向选择性局部回路实现此目的所需的侧向连接，以及由这些回路组成的网络的完整空间结构。我们将结果与各种生理学测量进行了比较。
