Pathway for bifurcation and reunion from single rods via pairs of RB cells to an AII amacrine cell 3. A: Rod 1 bifurcates to RB14 and RB17, and 24 of the 58 ribbon contacts at the RB14 axon and 34 of the 53 ribbon contacts at the RB17 axon are connected to AII 3. Likewise, the signals derived from rod 8 are reunited at AII 3 via 34 of the 53 contacts of RB17 and 31 of the 53 contacts of RB21. This AII amacrine cell receives a total of 116 inputs, 89 (77%) of which are provided by only these three major RB cells. Rods 1 and 8 correspond to the same rods as labeled in Figure 3. B1: The distal dendritic arbor (red) of AII 3 and the axon terminals of three major RB cells (RB14 in green, RB17 in yellow, and RB21 in blue). B2: Ribbon synapses in different colors, green for RB14, yellow for RB17, and blue for RB21. Scale bars = 5 μm.
