Table 1.
Published Talairach coordinates of the peak voxel activation in or near the human aIPS as reported by independent investigators using a variety of tasks. Asterisks denote that coordinates have been converted from Montreal Neurological Institute (MNI) (http://www.mrccbu.cam.ac.uk/Imaging/Common/mnispace.shtml). The row numbers (1-22) correspond to the numbers in the color-coded legend in Figure 1, in which these coordinates are superimposed on a high resolution template of a canonical brain.
