The t-map of each contrast was corrected for multiple comparisons using the AlphaSim command in AFNI (Cox, 1996; B. D. Ward, http://afni.nih.gov/afni/docpdf/AlphaSim.pdf). The individual voxel threshold probability threshold was set to be 0.05.
a
p<0.001.
b
p<0.05 (AlphaSim correction).
L, left; R, right; STG, superior temporal gyrus; IPL, inferior parietal lobule; SmG, supramarginal gyrus; MFG, middle frontal gyrus; MeFG, medial frontal gyrus; STP, superior parietal pole; SFG; superior frontal gyrus; MNI, Montreal Neurological Institute.
