∗Values represent MNI coordinates for significant activation maxima of clusters in the one sample t-test random effects analyses (p < 0.005, uncorrected with a minimum cluster size of k = 5). BA, Brodmann area; IPC, inferior parietal cortex; IFG, inferior frontal gyrus; MFG, middle frontal gyrus; IFG, inferior frontal gyrus.
