Anatomical distribution maps of ChR2-EYFP+ expression in rats. ChR2-EYFP expression was evident across the dorsolateral tuberal hypothalamic area particularly within the zona incerta, perifornical, and lateral hypothalamus. ChR2-EYFP emission signal was less prominent in the medial aspect of hypothalamus. Overall EYFP emission signal spread roughly 1.4 mm along the anteroposterior axis and it was present in both hemispheres. Just above the EYFP emission signal, the blue rectangles indicate the locations of the optic fiber tips. Optic fiber locations were drawn based on the presence of its tracks. The alphanumeric codes on top represent the identification number of the rat whereas the numbers on the far left represent the anterior-posterior distance from bregma.
