大脑的一个基本功能是通过新信息进行学习。对基于信息的学习过程的神经基础的研究表明，额叶后内侧皮质(PMFC)在代表个体的期望与新信息之间的冲突中发挥着重要作用。然而，pMFC在这一过程中的具体功能还相对不清楚。特别是，还不清楚pMFC是否在检测传入信息的冲突中发挥作用，或者在提供新信息后更新他们的信念。在fMRI扫描仪中，28名日本学生观看了描述各种亲社会/反社会行为的情景。参与者对日本和韩国学生做出每种行为的可能性进行了评级，然后反馈了实际的可能性。然后，他们被要求在功能磁共振成像课程后重新设定场景。参与者根据反馈更新了他们的第二次估计，尽管是国籍，但对于有利的反馈，估计的变化更明显(例如，亲社会行为的可能性比预期更高)，这表明参与者愿意对其他人持好感。FMRI结果显示，pMFC的一部分，背内侧前额叶皮质(DmPFC)的活动与社会冲突(参与者的估计与实际可能性之间的差异)有关，但与相应的信念更新无关。重要的是，dmPFC中不同部分的活动对不利的试验比有利的试验更敏感。这些结果表明，pmfc的敏感性(至少在dmpfc内)与期望结果与现实之间的冲突有关，而不是信念的更新。
A fundamental function of the brain is learning via new information. Studies investigating the neural basis of information-based learning processes indicate an important role played by the posterior medial frontal cortex (pMFC) in representing conflict between an individual's expectation and new information. However, specific function of the pMFC in this process remains relatively indistinct. Particularly, it’s unclear whether the pMFC plays a role in the detection ofconflictof incoming information, or theupdateof their belief after new information is provided. In an fMRI scanner, twenty-eight Japanese students viewed scenarios depicting various pro-social/anti-social behaviors. Participants rated how likely Japanese and South Korean students would perform each behavior, followed by feedback of the actual likelihood. They were then asked to rerate the scenarios after the fMRI session. Participants updated their second estimates based on feedback, with estimate changes more pronounced for favorable feedback (e.g., higher likelihood of pro-social behavior than expected) despite nationality, indicating participants were willing to view other people favorably. The fMRI results demonstrated activity in a part of the pMFC, the dorsomedial prefrontal cortex (dmPFC), was correlated with social conflict (difference between participant's estimate and actual likelihood), but not the corresponding belief update. Importantly, activity in a different part within the dmPFC was more sensitive tounfavorabletrials compared to favorable trials. These results indicate sensitivity in the pMFC (at least within the dmPFC) relates to conflict between desirable outcomes versus reality, as opposed to the associated update of belief.
