Summary of changes in MEMRI intraretinal signal intensity due to retinylamine treatment. (A) Pseudocolor linearized images of average retinal signal intensity in central retina of dark-adapted control male mice (left, control; n = 8) and retinylamine-treated mice (right, retinylamine; n = 6). The same pseudocolor scale was used for both linearized images, where blue to green to yellow to red represents the lowest to highest signal intensities. The intraretinal location used to extract the inner retinal (IR) and outer retinal (OR) data are indicated on the right of each linearized image. (B, C) Summary of inner and outer retinal signal intensities for control and retinylamine-treated mice. *Between-group comparisons between respective retinal regions with P < 0.05. Error bars, SEM. The y-axis scale starts at 50 because this is the premanganese baseline level determined from noninjected mice (data not shown).
