Efficiency of information coding in various L/M retinal cone ratios

Previous evidence has shown that the number of L and M cones in retina varies significantly between subjects. However, it is not clear how the variation of L/M ratio changes the behavioral performance of the subject. A model of transformation of data from retina to visual cortex for evaluation of various L/M cones ratios is presented. While L/M cone ratios close to 1 brings the best performance for one of postreceptoral [magnocellular] channels, we showed that the performance in the second channel [parvocells] will improve when the ratio furthers away from 1. effects of different ratios of S were also explored
