神经经济学这一新兴领域致力于将经济决策建立在大脑的生物基础上。我们使用最后通牒游戏玩家的功能磁共振成像来研究经济决策中涉及的认知和情感过程的神经基础。在这个游戏中，两个玩家平分一笔钱；一名玩家提议划分，另一名玩家可以接受或拒绝。我们扫描了玩家对公平和不公平提案的回应。不公平会引发与情绪（前岛叶）和认知（背外侧前额叶皮层）相关的大脑区域的活动。此外，因拒绝不公平的提议而导致前岛叶活动显着增强，这表明情绪在决策中发挥着重要作用。
The nascent field of neuroeconomics seeks to ground economic decision-making in the biological substrate of the brain. We used functional magnetic resonance imaging of Ultimatum Game players to investigate neural substrates of cognitive and emotional processes involved in economic decision-making. In this game, two players split a sum of money; one player proposes a division and the other can accept or reject this. We scanned players as they responded to fair and unfair proposals. Unfair offers elicited activity in brain areas related to both emotion ( anterior insula) and cognition ( dorsolateral prefrontal cortex). Further, significantly heightened activity in anterior insula for rejected unfair offers suggests an important role for emotions in decision-making.
