Histograms illustrating the average positive pixels and optical density of 5HT1A signal in the dorsal raphe nucleus of HSR and SS macaques treated with placebo or citalopram for 15 weeks (n=3–4/group). Two-way ANOVA was conducted. There was a significant effect of stress sensitivity on optical density (p=0.004) and on positive pixel area (p=0.001). However, there was no effect of drug treatment on optical density (p=0.89) or on positive pixel area (p= 0.83) and there was no interaction (p=0.17 for OD; p=0.072 for pixels).
