Overeating and addiction may have roots in early human brain evolution and prosocial behaviors

Research led by the Department of Anthropology and School of Biomedical Sciences, Kent State University, Ohio, has investigated neuropeptide Y innervation in an area of the brain called the nucleus accumbens of various primate species, including humans. The research was focused on understanding its role in brain evolution and any implications for human health, particularly regarding addiction and eating disorders.
