Experimental design of RGCs response and the results. Type I RGC (a) and a Type III RGC (b) to the electrically artificial stimulation. The histograms show the responses of Type I RGC to 20 repeated stimulations and Type III RGC to 32 repeated stimulations. For stimulation at 1.5 Hz, the bin width was 10 ms. The raster plots above the histograms show the spike activity of each stimulation
