Scientists identify neurons in the brain that drive competition and social behavior within groups
Scientists identify neurons in the brain that drive competition and social behavior within groups New research in mice has identified neurons in the brain that influence competitive interactions between individuals and that play a critical role in shaping the social behavior of groups. Published in Nature by a team led by investigators at Massachusetts General Hospital (MGH), the findings will be useful not only for scientists interested in human interactions but also for those who study neurocognitive conditions such as autism spectrum disorder and schizophrenia that are characterized by altered social behavior. "Social interactions in humans and animals occur most commonly in large groups, and these group interactions play a prominent role in sociology, ecology, psychology, economics and political science," says lead author S. William Li, an MD/PhD student at MGH. "What processes in the brain drive the complex dynamic behavior of social groups remains poorl...
