Fig 1. Concordance of Talairach and voxel-based findings in the posterior dorsal parietal lobe in RTT versus control subjects. Talairach-derived data (top row) show preferential bilateral reduction of GM in the posterior dorsal parietal lobe (outlined; only left side shown), corresponding with Brodmann areas 5 and 7. Similarly, VBM-derived data (bottom row) show bilateral GM volume reduction in the posterior dorsal parietal region (outlined), roughly corresponding with Brodmann area 7 (left hemisphere differences are depicted here).
