In our event-related functional magnetic resonance imaging (fMRI) experiment, participants learned to select between two response options by trial-and-error, using feedback stimuli that indicated monetary gains and losses. The results of the experiment indicate that error responses and error feedback activate the same region of dorsal anterior cingulate cortex, suggesting that this region is sensitive to both internal and external sources of error information.
在我们的事件相关功能磁共振成像（fMRI）实验中，参与者通过试错法学会在两个反应选项之间进行选择，使用指示金钱得失的反馈刺激。实验结果表明，错误反应和错误反馈激活了背侧前扣带回皮层的同一区域，这表明该区域对内部和外部错误信息源均敏感。
