ON Crossover pathways increase the threshold of OFF RGCs. (A) Peak value in space-time STA compared before and after L-AP4. Unity line is shown in black, and most points lie below indicating larger peak STA in control conditions. (B) Mean static nonlinearity before (blue) and after (red) L-AP4 are shown. The shaded area depicts 1 standard error around each point. There is a significant leftward shift in L-AP4 which indicates a decrease in threshold. (C) The 5% threshold is compared before and after L-AP4. Most points fall below the unity line.
