Figure 2. Spontaneous activity in Xenopus retinas.
Raster plots depicting RGC activity from albino (A) and pigmented wild type (B) Xenopus retinas. At each of three developmental stages indicated, 8 representative RGC spike trains that were recorded simultaneously are shown aligned in time. Insets expand 10s of activity. Activity patterns are comparable in albino and stage-matched wild type tadpoles. Stage 39/40: n=5 albino retinas, n=3 wild type retinas; Stage 46: n=6 albino retinas, n=3 wild type retinas; Stages 59-62: n=2 albino retinas, n=3 wild type retinas.
