Emory brain imaging studies reveal biological basis for human cooperation
Functional MRI scans
have revealed a "biologically embedded" basis for altruistic behavior, with several characteristic regions of the brain being activated when players of a game called "Prisoner's Dilemma" decide to trust each other and cooperate, rather than betray ea...
