Figure 6

Bottom Left : Spherical ROIs were placed into 4 sub-regions based upon the averaged anatomical image of the subjects in this study and demarcations suggest by Picard and Strick (2001). Vertical lines are drawn through the tip of the genu of the corpus callosum and through the anterior commisure, with the curved lines outlining RCZ between these landmarks. Spheres were placed in the cingulate gyrus anterior to the genu (blue), RCZa (red), RCZp (green), and pre-SMA (cyan) dorsal to RCZ and anterior to the anterior commisure. Top left: Conflict, Switching, and Error contrasts as a function of region. Top right: A comparison of Switching and Conflict contrasts by region. Bottom right: A direct contrast of Error and Switch trials (see Methods).
