FIGURE 6.
Representative images of c-Fos immunohistochemical staining (A), a marker of neuronal excitation, and statistical comparison of c-Fos positive neurons (B) in four subregions of the hypothalamic PVN in CON rats and CIH-exposed rats pretreated with ICV infusion of VEH or superoxide scavenger TEM. All data are presented as mean ± SEM (n = 5 for each group). ∗P < 0.05 vs. CON+VEH at the same subregion; †P < 0.05, CIH+TEM vs. CIH+VEH at the same subregion. pm, posterior magnocellular; dp, dorsal parvocellular; mp, medial parvocellular; vlp, ventrolateral parvocellular. Scale bar = 100 μm.
