Both social and material rewards play a crucial role in daily life and function as strong incentives for various goal-directed behaviors. However, it remains unclear whether the incentive effects of social and material reward are supported by common or distinct neural circuits. Here, we have addressed this issue by quantitatively synthesizing and comparing neural signatures underlying social (21 contrasts, 207 foci, 696 subjects) and monetary (94 contrasts, 1083 foci, 2060 subjects) reward anticipation. We demonstrated that social and monetary reward anticipation engaged a common neural circuit consisting of the ventral tegmental area, ventral striatum, anterior insula, and supplementary motor area, which are intensively connected during both task and resting states. Functional decoding findings indicate that this generic neural pathway mediates positive value, motivational relevance, and action preparation during reward anticipation, which together motivate individuals to prepare well for the response to the upcoming target. Our findings support the common neural currency hypothesis by providing the first meta-analytic evidence to quantitatively show the common involvement of brain regions in both social and material reward anticipation.
社会奖励和物质奖励在日常生活中都起着至关重要的作用，是各种目标导向行为的强大激励因素。然而，目前尚不清楚社会奖励和物质奖励的激励效应是否是由共同的或不同的神经回路所支持的。在这里，我们通过定量综合和比较社会奖励（21 个对比，207 个焦点，696 个被试）和金钱奖励（94 个对比，1083 个焦点，2060 个被试）预期的神经特征来解决这个问题。我们证明了社会奖励和金钱奖励预期涉及一个共同的神经回路，包括腹侧被盖区、腹侧纹状体、前岛叶和辅助运动区，这些区域在任务和静息状态下都有密集的连接。功能解码的发现表明，这条通用的神经通路介导了奖励预期过程中的正价值、动机相关性和动作准备，共同激励个体为即将到来的目标的反应做好充分准备。我们的研究结果支持了共同的神经货币假说，提供了第一个元分析证据，定量地表明了大脑区域在社会奖励和物质奖励预期中的共同参与。
