At threshold the eye is known to sum quanta as though the total catch were important and not the distribution on the retina. In humans, spatial summation is larger under dark adapted conditions. The extent of this spatial summation is studied in goldfish retinal ganglion cells which are known to receive both rod and cone inputs. The area of summation in single ganglion cells is found to be much larger for rod input compared to cone input. It seems that in single ganglion cells, the spatial summating properties increase markedly in the dark due largely to the neural organization of rod and cone input.
已知在阈值时，眼睛会对量子进行总和，就好像总的捕获量很重要，而不是视网膜上的分布很重要。在人类中，暗适应条件下的空间总和更大。在已知同时接受视杆和视锥输入的金鱼视网膜神经节细胞中研究了这种空间总和的程度。发现单个神经节细胞中视杆输入的总和面积比视锥输入大得多。似乎在单个神经节细胞中，空间总和特性在黑暗中会显著增加，这在很大程度上归因于视杆和视锥输入的神经组织。
