*
Brain regions containing clusters significantly more activated during evaluation of unpleasant words than neutral words. A cluster is considered activated if it contains ≥ 5 contiguous suprathreshold voxels (voxel threshold = Z ≥ 2.57 (P ≤ 0.005), cluster threshold = P ≤ 0.001) and contains at least one local maximum voxel for which Z ≥ 3.73 (P ≤ 0. 0001). Additional regions with local maxima within the same cluster are indented following the strongest local maximum for that cluster. L = left; R = right; B = bilateral; BA = Brodmann's Area in the region of observed activation.
