Coordinates refer to the voxels of maximum activation within clusters that reached significance only at uncorrected level (P < 0.05) k > 20. A statistical threshold of T > 2 (voxel level, uncorrected) was used. A cluster that did not reach significance in comparison G is marked with *. SPM 〈Z〉 I represents the shared activations of the SPM 〈Z〉 of A, C, & G each at a statistical threshold of T > 2 (voxel level, uncorrected). Coordinate conventions are as in Table I. The activations that resulted from comparisons A, C, F, and I are depicted in Figure 6.
