Fig. 8: Spatial resolution limit.
a Peri-stimulus time histograms (bins of 10 ms) for one RGC upon grating pattern reversal stimulation with decreasing bar widths (200, 160, 120, 100 and 70 µm). A grating pattern with black and green vertical bars (560 nm, 10 ms, 0.9 mW mm−2) was projected onto the array with a 5-Hz illumination rate for 3 s and reverted every five pulses. The first pattern and the reversals are highlighted by the grey dashed lines. The green triangles correspond to the onset of each light pulse. The red rectangles highlight ML activity. b Distribution of grating resolutions obtained in 18 RGCs.
