(A) zif268 in the dorsal hippocampus expressed as a proportion of total DAPI relative to the naïve control group 60 minutes following testing. Elevated zif268 activity in the dorsal hippocampus was observed in the no-exposure and extinction groups relative to a naïve control group but not in the weak-shock group. (B) Representative images from the dorsal hippocampus in each group, with DAPI staining in blue and zif268 staining in green. (C) zif268 in the basolateral amygdala expressed as a proportion of total DAPI relative to the naïve control group 60 minutes following testing. While all 3 groups showed elevated zif268 activity in the basolateral amygdala relative to a naïve control group, both weak shock and extinction reduced zif268. (D) Representative images from the basolateral amygdala in each group, with DAPI staining in blue and zif268 staining in green. ∗p < .05, ∗∗p < .01, ∗∗∗p < .001, ∗∗∗∗p < .0001. Scale bar = 100 μM.
