Activation centroids to EYES, MOUTH, and RADIAL. Two centroids are shown: anteriorly for the STS/ITS and posteriorly for the PTOF/LOS for coronal and axial fMRI studies. A, Right hemisphere. B, Left hemisphere. Centroids are superimposed on a sagittal view of a representative brain, 44 mm from the midline. In this and Figure 9, coordinates in they-axis (horizontal) andz-axis (vertical) are in the system of Talairach and Tournoux (1988), and the anterior commissure–posterior commissure line (horizontal line) and the anterior commissure at y = 0 (vertical line) are shown. The SEs around the centers of activation (x, y, z) for the coronal studies were EYES anterior (left, 1, 1, 2; right, 1, 1, 2), MOUTH anterior (left, 1, 3, 2; right, 3, 2, 2), EYES posterior (left, 1, 1, 2;right, 2, 2, 2), MOUTH posterior (left, 9, 2, 2; right, 3, 4, 2), and RADIAL posterior (left 1, 2, 1; right 2, 2, 2).
