Flexible attentional control depends on the integrity of a frontoparietal network that includes DLPFC. (A) Attention shifts engaged DLPFC bilaterally (P < 0.05, corrected). (B) The areas depicted in A served as seed volumes for a functional connectivity analysis that quantified coupling between DLPFC and other areas of a frontoparietal network that was active during attention shifts, including anterior cingulate (ACC), ventrolateral prefrontal (VLPFC), insula, premotor, ventral and dorsal areas of the posterior parietal cortex (PPC), and occipitotemporal visual areas including the fusiform cortex (P < 0.05, corrected). (C) Attention-shift performance depended on the integrity of this network. Decreased functional connectivity between left (i) and right (ii) DLPFC and areas of posterior parietal and premotor cortex was correlated with impaired attention shifting, independent of stress effects (P < 0.05, corrected). Scatterplots depict results for peak voxels in each cluster. See SI for details. ***, P < 0.005.
