Fear response and brain activation in juvenile rats infused with muscimol or vehicle in mPFC. (A) Percent time freezing in juvenile rats infused with vehicle or muscimol in mPFC and exposed to a non-threatening male or threatening cat odor. Mean ± SE. (B) Number of FOS positive cells in the amygdala and PAG of juvenile rats injected with vehicle or muscimol into infralimbic and prelimbic mPFC and exposed to a non-threatening male or threatening cat odor. Mean ± SE. N = 6–7 in each condition. (C) Cannula placement in infralimbic (left) and prelimbic mPFC (right) of juvenile rats. Open circles represent the location of cannula tips in rats infused with vehicle, and filled circles represent the location of cannula tips in rats infused with muscimol. Numbers indicate the distance in millimeters from bregma.
