Additional regions expressing forebrain pro-dynorphin. An ^a indicates regions with a main effect of stress, a ^b indicates regions with a main effect of drink p<0.05. An * indicates a significant difference from non-CVS control and a # indicates a significant difference from water control by post hoc analysis. Data are shown as mean ± SEM with n=5-9 per group.
