We learned that one cone is connected to a midget bipolar cell, and that about 50 cells in the periphery send the information to a diffuse bipolar cell. Based on these very different ways to send the information, try to explain why: (1) convergence is low or high in the fovea and periphery, respectively; (2) receptive fields are small or large; (3) acuity is high or low; and (4) light sensitivity is low or high.
