A PV and ChR2 expression in the retina. B Expression of ChR2 in a 12-¦Ìm retinal section. C¨CD High magnification images of the areas labeled by the squares in A. E PV and ChR2 expression in the dLGN and V1. F High magnification of the area (V1) enclosed by the upper square in E. G High magnification of the area (dLGN) enclosed by the lower square in E.
