From: Study of the nitric oxide system in the rat cerebellum during aging
Photomontage of nNOS immunoreactivity in the nuclei of rat cerebellum rostro-caudal sections. Panels A and C: adult rat. Panels B and D old rat. nNOS immunoreactive neurons (arrowheads) in the fastigial (fg), interposed (ip), and dentate (dt) cerebellar nuclei of adult and aged rats are observed (A-D). Scale bars: A and B, 200 μm; C and D, 20 μm.
