The study examined cooperation in mice and artificial intelligence systems as they learn to coordinate actions to achieve shared rewards.1][2] In mice, key social behavioral strategies and decision-making processes that facilitate successful cooperation have been identified.2][3] These processes are represented in the anterior cingulate cortex (ACC), and ACC activity directly contributes to cooperative behavior.1][2] Inhibition of ACC activity significantly reduced cooperation in the animals.1][2] Artificial agents trained in a similar task developed similar behavioral strategies and neural representations as biological brains.[1][2] Both systems formed functional groups of neurons that improved response to cooperative stimuli, with partner information gaining in importance with better coordination.1][1] Selective disruption of cooperative neurons in AI dramatically reduced the performance of cooperation.[1] Research has revealed fundamental principles of cooperation common to biological and artificial systems.[1][2
