Clusters achieving p< 0.05 corrected for False Discovery Rate (FDR) are denoted by *, other clusters indicated are at the trend-level of p< 0.001, uncorrected.
For each cluster, the peak location is given in MNI coordinates, accompanied by location in terms of Brodmann’s area and sulcal/gyral locus. T values represent the peak voxel activation within each cluster. Clusters have been thresholded at 10 voxels (80 mm3).
