Functional magnetic resonance imaging (fMRI) has become a valuable tool for investigating brain function in both human and nonhuman primates. This comparative approach allows researchers to gain insights into the similarities and differences in neural processing, cognitive abilities, and functional brain networks between species. In this paper, we argue that advances in MRI technology have made it possible to directly study brain responses in a wide range of animals, including macaques, allowing us to answer questions about sociality, bond formation, and the evolution of cooperation that were previously unanswerable in the field.
