Correlation of Impulsivity-related Factor 5 (Behavorial Risk-Taking) scores with neural activation under the reward-punishment contrast across all subjects.

<p><b>A</b>. Threshold was set at p<0.05 FWE for voxels within the reward network mask. Statistical parametric F-maps (sagittal, coronal and axial) of the Reward-Punishment contrast for multiple regression against Factor 5 - “Behavioral Risk-Taking”. Crosshairs overlaid on brain slices are at the voxel of peak correlation (MNI coordinates: x,y,z = 12,4,–8). Bottom panel depicts individual factor scores vs. individual peak cluster activation at this voxel. <b>B</b>. Linear regression plot at the voxel of peak correlation between reward-punishment BOLD activity in the right ventral caudate and Factor-5 score for each subject.
