We aim to investigate evolutionary differences of functional connectivity between humans and nonhuman primates. Specifically, we identified resting-state networks in a large nonhuman primate (baboons, Old World monkeys) who is evolutionary close to humans, and we compared the similarities and discrepancies with networks found in humans. We observed similar networks associated with primary functions in both species, however, networks were more asymmetric in baboons.
