We conducted studies with an ultimate aim of elucidating neural computations for social decision making. While we made several achievements towards the aim, here we summarize the result of a most central study. Using human fMRI experiment, combined with so-called model-based analysis, we investigated brain functions for value-based decision making, comparing two situations ; when the subject makes value-based decisions for their self reward and when the subjects predicts what value-based decision another person would make, when the other person is in the same situation for themselves. We found that the ventromedial frontal cortex plays a central role in simulating the other's value-based decision making process.

我们进行了研究，以阐明神经计算进行社会决策的最终目的。尽管我们朝着目标取得了一些成就，但在这里，我们总结了一项最中心研究的结果。使用人类fMRI实验，结合了所谓的基于模型的分析，我们研究了用于基于价值决策的大脑功能，并比较两种情况。当受试者为自己的自我奖励做出基于价值的决策，而当受试者预测另一个人将做出的基于价值的决定时，当对方对自己处于同一情况时。我们发现，腹侧额叶皮层在模拟对方的基于价值的决策过程中起着核心作用。
