Rods vs cones fovea
WebBipolar cells receive synaptic input from either rods or cones, or both rods and cones, though they are generally designated rod bipolar or cone bipolar cells. There are roughly 10 distinct forms of cone bipolar cells, however, only one rod bipolar cell, due to the rod receptor arriving later in the evolutionary history than the cone receptor [ attribution … Web6 Jan 2010 · Rods don't help with color vision, which is why at night, we see everything in a gray scale.
