Coordinates for each local maxima within significant clusters of activity (cluster-corrected p < 0.05) are given for the components shown in Figure 2. PCC, Posterior cingulate cortex; SMG, supramarginal gyrus. For each component, the percentage of the total variance in the data explained by that component is given in parentheses.
