We present coordinates of activation foci together with Z-scores and an estimate of location relative to gross anatomy for each contrast of interest. MFG, Middle frontal gyrus; MTG, middle temporal gyrus; SFS, superior frontal sulcus; STP, superior temporal planum; STG, superior temporal gyrus; Vathal, ventral anterior thalamic nucleus; R, right; L, left. All peak voxels exceeding p < 0.001 are reported. Voxels marked with an asterisk reach whole-brain FDR correction at p = 0.05. Note that, because the FDR correction is an adaptive procedure, statistical thresholds are at different values for the two contrasts.
