The aim of the present study was to examine the neural signatures of gaining money for self and charity. Young adults (N = 31, 21-24 years of age) underwent fMRI scanning while they performed a task in which they could earn money for themselves and for a self-chosen charity by selecting one of two options with unknown outcomes. The results showed elevated activity in the ventral striatum when gaining for the self only and for self and charity, but not when gaining for charity only. However, increased ventral striatal activity when gaining for charity only was correlated with participants' self-reported empathic concern and enjoyment when winning for charity. Empathic concern was also related to donating a larger proportion of earnings to charity after the MRI session. In short, these results reveal robust ventral striatal activity when gaining for oneself, but empathy-dependent individual differences in ventral striatal activity when gaining for charity.
本研究的目的是检验为自己和慈善事业赚钱的神经特征。年轻成年人（N = 31，年龄在21至24岁之间）在进行功能性磁共振成像（fMRI）扫描时，执行一项任务，在该任务中，他们可以通过选择两个结果未知的选项之一，为自己和自选的慈善机构赚取金钱。结果显示，仅为自己赚钱以及为自己和慈善事业赚钱时，腹侧纹状体的活动增强，但仅为慈善事业赚钱时则不然。然而，仅为慈善事业赚钱时腹侧纹状体活动的增加与参与者自我报告的在为慈善事业获胜时的共情关注和愉悦感相关。共情关注也与在磁共振成像（MRI） session后将更大比例的收入捐赠给慈善事业有关。简而言之，这些结果揭示了为自己赚钱时腹侧纹状体有强烈活动，但为慈善事业赚钱时腹侧纹状体活动存在依赖于共情的个体差异。
