Note: Results are from regressions focusing on the striatum and the rostral medial prefrontal cortex. df=75 for subjective positive affect and 74 for depressive symptoms. For clusters labeled Thalamus/Caudate, the maximum voxel for the cluster was located in the thalamus, but most of the cluster was located in the caudate. BA: Brodmann Area. FDR: False discovery rate-corrected. When excluding cases with depressive symptoms >30, the correlations with BA32 during reward anticipation (63 voxels, [-4,34,4], t=2.69, p<.005) and striatum during reward outcome (caudate: 103 voxels, [-2,12,6], t=2.95, p<.005) remained significant.
