Figure 4.
Effect of sc Ang II infusion on neuronal activity in the SFO of wild-type mice. Ang II infusion (1000 ng/kg · min) for 1 week (A) or 2 weeks (B) significantly increased the positive cell number of c-Fos in the SFO. Microphotographs (×20 magnification) of c-Fos immunoreactivity in the SFO and quantification data are displayed. Values are mean ± SEM, n = 5–8 per treatment; *, P < .05, t test.
