视杆和视锥光感受器的光响应的动力学、增益和可靠性是整体视觉灵敏度的重要决定因素。在完整的灵长类动物视网膜的光感受器的电压记录中，发现杆在功能上彼此隔离，不像冷血脊椎动物的紧密耦合杆。视锥细胞接受来自视杆细胞的兴奋性信号，这表明视锥细胞通路也处理视杆细胞信号。这种输入可能会降低中间视觉的空间分辨率。
The kinetics, gain, and reliability of light responses of rod and cone photoreceptors are important determinants of overall visual sensitivity. In voltage recordings from photoreceptors in an intact primate retina, rods were found to be functionally isolated from each other, unlike the tightly coupled rods of cold-blooded vertebrates. Cones were observed to receive excitatory input from rods, which indicates that the cone pathway also processes rod signals. This input might be expected to degrade the spatial resolution of mesopic vision.
