From: Study of the nitric oxide system in the rat cerebellum during aging
Microphotographies of eNOS immunoreactivity in the cortex of rat cerebellum rostro-caudal sections. Panels A and B: adult rat. Panels C and D: old rat. eNOS immunoreactive Purkinje cells (pc) and blood vessels (arrowheads) can be appreciated in both age groups. g: granular layer; m: molecular layer; p: Purkinje cells layer; wm: white matter. Scale bars: A and C, 100 μm; B and D, 20 μm.
