感受野和拓扑图对的识别

RECEPTIVE FIELDS AND DISCRIMINATION OF TOPOLOGICAL FIGURE PAIR

本文把感受野作为一个线性系统,以广义Gabor函数为其核函数,拓扑特性相同或不同的图对为输入刺激,计算出相应输出反应,结果和心理物理实验结果定性一致,说明感受野可能是对一些简单图对进行识别的神经生理基础。

This paper considers receptive fields of the visual system a linear sys-tem for the processing of images. The kernal function of this system isExtended Gabor Funcion (EGF). For testing this system, several pairs ofinput patterns different or same in topology were used. The results ob-tained from this model were consistent with those of psychophysical experi-ments qualitatively. These simulated results showed that receptive fieldsin the visual system are the neural mechanism of pattern dicrimination inpsychology.
