Stimulus area-response functions of retinal ganglion cells show an extensive disinhibitory region (DIR) outside the classical receptive field (RF). The DIR has a wide summation area but low sensitivity. Spatial responses of the retinal ganglion cells have been simulated in a model which takes into account also the properties of the DIR. By scanning the RF and its DIR with a visual image and reconstructing the transferred image for single cells, it is shown that these properties of the DIR are beneficial in the transmission of area brightness and image grey scales.
视网膜神经节细胞的刺激区域-反应函数在经典感受野（RF）之外显示出一个广泛的去抑制区域（DIR）。DIR具有广泛的总和区域但灵敏度较低。视网膜神经节细胞的空间反应已在一个模型中进行了模拟，该模型也考虑了DIR的特性。通过用视觉图像扫描RF及其DIR并为单个细胞重建传输图像，结果表明DIR的这些特性在区域亮度和图像灰度级的传输中是有益的。
