Comparative analysis of human and macaque IPL areas. A: Multidimensional scaling analysis reveals the segregation of human and macaque areas by the first dimension, whereas the second dimension reflects changes in receptor fingerprints along the rostro-caudal axis of each species. Note, that to facilitate interpretation of the results, the MDS plot has been rotated counter-clockwise by 90° and flipped horizontally. Thus, human areas are found at the top of the plot and macaque areas at the bottom. Rostral areas are to the left, caudal ones to the right. Dashed lines with arrows connect homolog areas. B: Schematic representation of the topographic relationship between IPL areas in the human (top) and macaque (bottom) brains. Colour coding represents clusters as revealed by hierarchical cluster analyses, the detailed information of macaque clusters can be found in Figure 6. Three receptor-architectonically distinct clusters in human were found by Caspers S et al. (2012): a caudal cluster (red) consisting of areas PGp and PGa; an intermediate cluster (green) consisting of areas PFm and PF, and a rostral cluster (blue) consisting of areas PFt, PFcm and PFop.
