S-Cone OFF midget bipolar cells are indistinguishable from L- and M-cone OFF midget bipolar cells. For comparison, we show reconstructions of two OFF midget bipolar cells contacted by the terminals of S-cones 144 and 35 and two OFF midget bipolar cells contacted by the terminals of L/M cones. INL, Inner nuclear layer; OPL, outer plexiform layer. Scale bar, 10 μm.
