Figure 3
Example photographs taken from retina wholemounts of wild-type and M1R−/− mice at both age categories (A–D; scale bars 10 µm). Total number of cells (E), of neurons (F), endothelial cells (G) and glia cells (H) in the RGC layer. The total number of cells and number of neurons in the RGC layer was found lower in old M1R−/− mice than in young mice of the same genetic background (***P < 0.001).
