摘要:
随着脑成像技术的不断发展，研究者试图通过脑成像技术研究人格特质的内在神经生理机制。本文对人格的核心特质——外倾性的MRI研究(包括任务态的、静息的、结构的)进行回顾和总结，以期更好地理解外倾性特质的神经机制。研究发现，外倾性与脑岛、腹侧纹状体、杏仁核、眶额叶、楔前叶、前扣带等“社会脑网络”脑区功能或结构的改变有关。未来的研究需要综合考虑测量手段、选择恰当研究范式，并尽可能考虑年龄、性别、实验刺激类型、被试类型、样本数量等一些因素的影响。With the development of brain imaging technology, the brain mechanism of personality has captured the attention of researchers for several years. In the present review, MRI researches (including task- fMRI, resting-fMRI, and structural MRI) of extroversion were summarized in order to help understand the neural mechanism of extraversion traits. In summary, extraversion was found to be highly correlated to the functional and structural changes in insula, ventral striatum, amygdala, the medial prefrontal cortex, precu- neate cortex, and anterior cingulated cortex, which were referred to as the social brain network. Future researchers had better choose multiple measurements of extraversion, flexible study design with better ecological validity, and control other extra factors, such as age, gender, stimulus type, subjects’ type and sample size.
