All coordinates are described according to the Montreal Neurological Institute system, and were obtained through a random effects (uncorrected, p < 0.005, 10 voxel cluster threshold) analysis of data.Abbreviations: SMA, supplementary motor area; IFG-P-Op, inferior frontal gyrus pars opercularis; IFG-P-Tr, inferior frontal gyrus pars triangularis; STG, superior temporal gyrus; FPPFC, frontopolar prefrontal cortex; DLPFC, dorsolateral prefrontal cortex; DMPFC, dorsomedial prefrontal cortex; MCC, middle cingulate cortex; ACC, anterior cingulate cortex; AG, angular gyrus.
