Figure 7. Fos expression in the PVH, RCA and SCN after unilateral chemo-stimulation in the SCN, or RCA or PVH.
Chemogenetic activation of the unilateral SCN increases Fos expression in ipsilateral PVH and RCA (D-F), compared to sham group (A-B). Fos-ir positive cell in the ipsilateral PVH, RCA and l SCN were induced after unilateral SCN, PVH or RCA activation (C). Chemogenetic activation of the unilateral PVH did not alter Fos expression in contralateral PVH or SCN or RCA (G-I). Chemogenetic activation of unilateral RCA did not influence Fos expression in the PVH, but appeared to induce Fos expression in SCN (J-L).
