Voxels: number of activated voxels in a cluster. Clusters were generated by the voxel-by-voxel group analysis and extracted with the 3dclust algorithm from AFNI (Cox, 1996). X, Y, and Z coordinates are based according to the Talairach & Tournoux Atlas within AFNI and represent the maximum intensity of a cluster. Abbreviations: L = left, R = right, G = gyrus, BA = brodmann area, N = nucleus, Parahipp = parahippocampus, IFG = inferior frontal gyrus, MFG = middle frontal gyrus, tlrc: talairach coordinates, Max Int: maximum intensity.
