Peak coordinates (x,y,z) are listed in MNI space. T values are test statistics derived from 5000 permutations of the data. All regions are significant at p < 0.05 whole-brain familywise error corrected for multiple comparisons.

IFG, Inferior frontal gyrus; SFG, superior frontal gyrus; R, right; L, left.
