Figure 3. Correlations between striatal dopamine synthesis capacity and acute response to psychosocial stress.

(A) Whole striatal dopamine synthesis capacity was positively correlated with stress-induced threat in the Low Adversity group (r = 0.73, p=0.001) but not the High Adversity group (r = −0.03, p=0.934). (B). Whole striatal dopamine synthesis capacity was negatively correlated with stress-induced threat and mean arterial blood pressure in the Low Adversity group (r = −0.62, p=0.013) but not the High Adversity group (r = 0.23, p=0.395). Extreme bivariate outliers have been removed from the figures.
