Chronic stress increases activity of prefrontal PV⁺ neurons in males and females. (A) Representative image showing PV (red) and cFos (green) double-labeling (white arrow) and DAPI (blue). Scale bar: 10 µm. (B) Chronic stress increases the number of PV/cFos double-labeled cells in the mPFC of females and males. *p = 0.05; ***p < 0.001.
