Volumetric position discrimination maps were created for each subject as in Figure 5, and the voxel within the right pulvinar with the largest slope value was taken as the location of peak position discrimination. Although there was some variability from subject to subject, in five of the seven subjects the location of peak discrimination fell in the lateral portion of the right pulvinar ROI, within the region corresponding to the PLvl subdivision in macaques. This matches the region of peak position discrimination that we found in Figure 5.
