Average brain activations associated with conflict resolution.
(A) Increased activation during conflict resolution was
detected in frontal, temporal, parietal, and striatal regions. Increases in
signal are in red and decreases in blue. (B) Activation during
conflict resolution in frontostriatal regions, hippocampus, and amygdala
inversely associated with VIQ>PIQ discrepancy. Positive correlations are
in red and inverse in blue. (C) Scatterplots demonstrate decreasing
activation in left (−38,38,−8) and right (48,23,13) IFG, left
(−21, −7, −23) and right (27, −2, −18)
amygdala, and right Put (34,−7,−5 ) and Hippocampus
(−34, −25, −10) with increasing magnitude of
VIQ>PIQ discrepancy. Maps (generated with MRIcroN; McCausland Center for
Brain Imaging, Columbia, South Carolina) are thresholded at p < .0125,
with cluster filter 38. ACC, anterior cingulate cortex; AMY, amygdala; FG,
fusiform gyrus; Hi, hippocampus; IFG, inferior frontal gyrus; IPL, inferior
parietal lobule; IT, inferior temporal gyrus; PreCG, precentral gyrus; PreCun,
precuneus; Put, putamen; Thal, thalamus; SFG, superior frontal gyrus.
