About half of the monophasic horizontal cells in carp retina receive input from both red- and green-sensitive cones. Since the horizontal cells feed back to cones, the color and feedback pathways result in wavelength- and intensity-dependent changes of the dynamics and of the receptive field amplitude profile of the horizontal cell responses. In this paper we present a quantitative model that describes adequately the color and spatial coding and the dynamics of the responses from monophasic horizontal cells in carp. Lateral feedback plays a distinct role in this model.
鲤鱼视网膜中约一半的单相水平细胞接收来自红色和绿色敏感视锥细胞的输入。由于水平细胞会反馈到视锥细胞,颜色和反馈通路导致水平细胞反应的动力学以及感受野幅度分布随波长和强度发生变化。在本文中,我们提出了一个定量模型,该模型能够充分描述鲤鱼单相水平细胞的颜色和空间编码以及反应动力学。横向反馈在该模型中起着独特的作用。
