Conflict-related activity for the L′ (n=14) vs S′ (n=19) participants. (a) Axial, saggital, and coronal slices showing the dACC cluster (incongruent vs congruent) thresholded at p<0.005 (x=−2, y=25, z=20). (b) Mean (and SE) β-weights extracted from the dACC cluster exceeding the statistical threshold (p<0.05, corrected). (c) dACC cluster reported in a previous ERP study, in which MDD subjects exhibited decreased current density relative to control participants 620 ms after the presentation of an incongruent trial in a Stroop task (peak voxel Talairach coordinates: x=−10, y=25, z=33; Holmes and Pizzagalli, 2008a). The Euclidian distance between the fMRI and ERP voxel is 15.8 mm.
