The impact of prior sucrose (vs. water) on the plasma ACTH (A, B) and corticosterone (C, D) responses to an acute restraint stress in female rats tested during diestrus (D1/D2) (A, C) and proestrus/estrus (P/E) (B, D). *p < 0.05 vs. water. n = 9–15/group. Note that for each hormone, data were analyzed via 3-way repeated measures ANOVA comparing DRINK, CYCLE, and TIME, but are graphed separated by estrous cycle stage to aid visualization.
