Interactions with other responsive agents lie at the core of all social exchange. 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.
与其他反应性主体的互动是所有社会交换的核心。在与伙伴进行社会交换时，一个必须正确计算的基本变量是谁因共同成果而获得认可；这种分配对于确定避免简单剥削的最佳合作水平至关重要。我们进行了一场重复的两人经济交换，并同时测量了每个参与者大脑的血液动力学变化。这些联合测量揭示了社会领域中特定主体的反应（“我”和“非我”），它们沿着扣带回皮质以一种系统的空间模式排列。这种系统的反应模式并不取决于交换的度量方面，并且在没有反应性伙伴的情况下会完全消失。
