Reduced retinal response in aged marmosets. (a, b) Representative images of three-dimensional plots depicting averaged visual responses of the second-order kernel (a) and first-order kernel (b) examined by multifocal electroretinogram (mfERG). A higher score (white) indicates highly sensitive visual function, and a lower score (green) indicates retinal dysfunction. Values are given in nV per square degree (nV/deg2). (c, d) Quantitative analysis of the retinal responses of second-order kernel (c) and first-order kernel (d). n = 10 from both eyes of 5 young marmosets (Y) and 8 from both eyes of 4 aged marmosets (A). *P < 0.05 (Mann–Whitney U test). Data are expressed as the mean ± S.E.M.
