摘　　要：目的探讨社区人群与说谎有关的认知模式及神经联系。方法对社区志愿者进行说真话及说谎条件下的功能磁共振扫描。使用SPM2软件分析受试在两条件下脑区激活的差异。结果说谎任务对比说真话任务，受试双侧背外侧前额叶、额内侧回、顶下小叶、右颞下回及小脑激活显著增加。结论大脑的特定区域参与说谎或说真话，并能被功能磁共振成像（fMRI）检测到。Objective To investigate the cognitive mode of deception in community group. Methods Functional magnetic resonance imaging in conjunction with statistical parametric mapping was applied to the community recruited volunteers in the condition of telling truth and lying. Results Compared with telling truth, bilateral dorsalateral prefrontal cortex, medial frontal cortex, inferior parietal cortex, fight inferior temporal cortex and cerebellum were significantly activated when subjects lying. Conclusion Lying is related with specific brain region and is able to be detected by functional magnetic resonance imaging.
