Short- and long-term effects of adolescent CMS on ventral hippocampus GR mRNA expression in control and PAE rats. Bars represent the mean ± SEM (mean gray value) of GR mRNA expression in the CA1 (A-D), CA3 (E-H), DG (I-L), and ventral subiculum (M-P). § indicates a significant main effect of CMS exposure, where all animals exposed to CMS are different from animals not exposed to CMS; for B, # indicates that PAE non-CMS is different from control non-CMS based on a priori comparisons; for D, # indicates that control CMS is different from control non-CMS based on a priori comparisons; (n = 4-10 for all groups).
