Brain regions show positive correlations between the Fisher Temperament Inventory Scores and neural activation in two independent studies within the Positive>Neutral contrast.

Regions of interest analysis noted by superscripts. MNI coordinates (x,y,z) are at the maximum value for the cluster, which may be elongated in any direction.1We searched dopamine and norepinephrine-rich regions.2From Spitzer et al., [32]: both regions in the two groups were correlated with social norm compliance.3From refs [33].4Exploratory analysis.
