The prospect to unveil the network architecture of the human brain has recently achieved large progress through the advancements in diffusion MRI and tractography. However, such effort in chimpanzees is lacking. Chimpanzees are our closest living relatives, and comparing their brain networks with those of humans may shed light on the unique cognitive and language abilities owned by humans. Here, we investigated the effects of parcellation schemes on the chimpanzee cerebral cortex as the first step to establish a framework to derive and compare brain connectivity networks across three species.
