Figure 12

Electron microscopy of the IPL. Electron micrographs showing similar examples of ribbon (R) and conventional synapses (arrows) in the IPL of retinal samples obtained at matching locations from Pax6α:Cre; Brn3bCKOAP/KO (A–C) and Pax6α:Cre; Brn3bCKOAP/WT mice (D–E). RBe, rod bipolar ending; CBe, cone bipolar endings. Arrows indicate the direction of synaptic transmission. Ribbons label the presynaptic endings of rod and cone bipolars, while conventional synapses are established by amacrine cells only. Scale bar = 1 µm in B (applies to A,B), C, and E (applies to D,E).
