All activations were significant at P < 0.01, uncorrected for multiple comparisons. Standardized coordinates indicate locations of peak activations. Asterisks indicate whether activations were found in supramarginal gyrus (SMG), angular gyrus (ANG) and/or the superior parietal lobule (SPL). K = number of voxels per cluster. Note that a given subject may have multiple clusters. See text for details.
