Figure 5.

Plasma corticosterone concentration (ng/ml). Baseline values and concentrations for each group at the end of experiment 1 (T1) (a) and experiment 2 (T2) (b). Experimental design is described in Figure 1. All experimental groups were composed of seven animals (n = 7). Data are expressed as mean and standard error. One‐way ANOVA and Bonferroni's post hoc test correction were used to determine statistically significant differences between the baseline values and the groups C and MS in (a) and C+SUC, MS+SUC, C+EtOH and MS+EtOH in (b). *p < .05 baseline versus C and baseline versus MS in (a); and *p < .05 baseline versus C+SUC, baseline versus MS+SUC, baseline versus C+EtOH, and baseline versus MS+EtOH in (b)
