Note: All results are thresholded at P < 0.01 (cluster corrected) except for cross-task decoding of action from identification to pantomime (thresholded at P < 0.05, cluster corrected). Regions for which the cluster size (mm) is indicated as “–” were contiguous with the region directly above, and hence included in the above volume calculation. SMG, supramarginal gyrus; aIPS, anterior inferior parietal sulcus.
