Portions of the left putamen where voxel-based morphometry showed a statistical difference between the stenographers and the controls. The stenographers exhibited an enlarged putamen compared to the controls in the left dorsal anterior part of the putamen. The black arrow indicates the peak voxel (P = 0.0021 with a coordinate of (−24, 14, 5)). To define the activated regions, a statistical threshold of P < 0.005 (uncorrected) was used.
