During a social exchange with a partner, one fundamental variable that must be computed correctly is who gets credit for a shared outcome; this assignment is crucial for deciding on an optimal level of cooperation that avoids simple exploitation. We carried out an iterated, two-person economic exchange and made simultaneous hemodynamic measurements from each player's brain. These joint measurements revealed agent-specific responses in the social domain ("me" and "not me") arranged in a systematic spatial pattern along the cingulate cortex. This systematic response pattern did not depend on metrical aspects of the exchange, and it disappeared completely in the absence of a responding partner. 10.1126/science.1125596 Agent-Specific Responses in the Cingulate Cortex During Economic Exchanges Damon Tomlin Amin Kayali Brooks King-Casas Cedric Anen Colin Camerer Steven Quartz Read Montague doi:10.1126/science.1125596 Science, Vol. 312, No. 5776.
