Figure 4.

Nonoverlapping populations of RGCs project to the SC and MTN. A, Top, Retina from an animal in which beads conjugated to rhodamine and fluorescein were injected into the SC and MTN, respectively. The number of cells labeled by red, green, and red and green beads is shown below. B, XY and XZ projections of morphological reconstructions of representative MTN-projecting and SC-projecting On DS RGCs and SC-projecting On-Off DS RGCs. Scale bar, 50 μm. C, Dendritic asymmetry, area, length, and percentage volume in the Off sublamina of the inner plexiform layer for three classes of DS RGCs (n = 7, 5, and 3 cells reconstructed, respectively).
