Location and extent of IPL areas in the macaque monkey brain. A: 3D reconstruction of the left hemisphere (in lateral view) of Macaca mulatta (DP1) brain obtained using Connectome Workbench software (https://www.humanconnectome.org/software/connectome-workbench) showing the location and extent of the areas that compose the IPL (map made publicly available at https://balsa.wustl.edu/study/7qgpZ). The enlarged reconstruction scheme indicates the approximate positions of cut plane (a-i) for a series of exemplary coronal sections, which were processed for the visualization of topography of IPL areas. B-E: Low magnification views of representative fields of IPL areas taken from the four exemplary coronal sections. For each section, the dashed boxes indicate the location of the photomicrographs; arrows indicate the borders between cytoarchitectonic areas. The cytoarchitectonic subdivisions of the IPL convexity, areas Opt, PG, PFG and PF, are shown in B, C, D and E, respectively. The opercular area PGop is shown in C, PFop are shown in D and E. Dorsal is up and lateral on the right. Scale bar, 500 μm.
