The present study examined the neural correlates of evaluations of both lying and truth-telling in different social contexts using fMRI methodology. The results demonstrated the differentiation between lying and truth-telling and between different types of lying in a network of brain regions. These regions included bilateral superior frontal gyrus (SFG), bilateral inferior parietal lobule (IPL), bilateral cuneus, right lingual gyrus (LG), right precuneus, and left postcentral gyrus (PoCG). Additionally, we found that activations in the right LG, the left IPL and the left PoCG were correlated with the off-line evaluations of truthful and untruthful communications about good and bad acts in different social contexts. These results suggest that the judgments of lying and truth-telling involving a third party might not be emotion-arousing but involve rational processing. This study is among the first to demonstrate that evaluations of truthful and untruthful communications in different social contexts can be differentiated in terms of brain BOLD (blood-oxygen-level-dependent) activities.
本研究使用 fMRI 方法探讨了不同社会情境下对说谎和说真话的评价的神经相关性。结果表明，在一个脑区网络中，可以区分说谎和说真话，以及不同类型的说谎。这些区域包括双侧额上回（SFG）、双侧顶下小叶（IPL）、双侧楔叶、右侧舌回（LG）、右侧楔前叶和左侧中央后回（PoCG）。此外，我们发现右 LG、左 IPL 和左 PoCG 的激活与离线评估不同社会情境下关于善恶行为的真实和不真实沟通有关。这些结果表明，涉及第三方的说谎和说真话的判断可能不会引起情绪反应，但涉及理性处理。这项研究是首次证明，不同社会情境下对真实和不真实沟通的评估可以在大脑 BOLD（血氧水平依赖）活动方面进行区分。
