Fig 1: Inhibition of the PERK pathway alleviated expression of CHOP in glutamatergic neurons in the BLA of stressed rats. (a) Representative images are showing CHOP immunohistochemistry in the BLA. Images obtained by MMTC are shown in the lower-left corners. (A'–D') are magnified areas of (A–D). Bars = 200 µm in (A–D); bars = 50 µm in (A'–D'). (b) Quantitative MMTC analysis. Data are shown as mean ± SEM; **P < 0.01 vs. the control group, *P < 0.05 vs. the stress group (n = 5).
