Representative digital images of FosB/ΔFosB staining on one side in PVN regions of scRNA (A) and shRNA (B) rats. Parvocellular and magnocellular subdivisions are diagrammed in the scRNA (A). Image C indicates the mean no. of FosB/ΔFosB-positive cells counted in the different regions with in paraventricular nucleus (PVN). *P value <0.05 vs. scRNA; n = 8/group. dp, Dorsal parvocellular; mp, medial parvocellular; pm, posterior magnocellular; lp, lateral parvocellular (not shown in image A, as it is found at different level of PVN), Scale bar = 100 μm.
