先前对大脑损伤、功能活动和灰质结构的研究表明，情绪智力（EI）与参与社会认知网络（SCN）和体细胞标记电路（SMC）的区域相关。我们的新研究首次调查了白质 (WM) 完整性与 EI 之间的关联。我们检查了健康年轻成年男性 [n = 74，平均年龄 = 21.5 岁，标准差 (SD) = 1.6] 和女性 (n = 44，平均年龄 = 21.9 岁，SD = 1.4) 的大脑中的这种关系。我们使用扩散张量成像对分数各向异性进行了基于体素的分析，分数各向异性是 WM 完整性的指标，并使用问卷（EI 量表）来测量 EI，以确定 WM 完整性与个体 EI 因素（人际因素、人际因素和情境管理因素）的相关性。我们的结果表明，（a）EI 的个人因素与右前岛叶的 WM 完整性呈正相关，（b）EI 的人际因素与右下纵束（ILF）部分的 WM 完整性相关。右前岛叶是 SMC 的重要节点之一，而 ILF 连接视觉皮层和 SCN 相关区域，因此是 SCN 的一部分。我们的研究结果进一步支持了涉及 SCN 和 SMC 的大脑区域与 EI 相关的观点。 Hum Brain Mapp，2013 年。© 2011 Wiley periodicals, Inc.
Previous studies of brain lesions, functional activity, and gray matter structures have suggested that emotional intelligence (EI) is associated with regions involved in the network of social cognition (SCN) and in somatic marker circuitry (SMC). Our new study is the first to investigate the association between white matter (WM) integrity and EI. We examined this relationship in the brain of healthy young adult men [n = 74, mean age = 21.5 years, standard deviation (SD) = 1.6] and women (n = 44, mean age = 21.9 years, SD = 1.4). We performed a voxel‐based analysis of fractional anisotropy, which is an indicator of WM integrity, using diffusion tensor imaging and used a questionnaire (EI Scale) for measuring EI to identify the correlation of WM integrity with individual EI factor (intrapersonal, interpersonal, and situation management factors). Our results showed that (a) the intrapersonal factor of EI was positively correlated with WM integrity in the right anterior insula, and (b) the interpersonal factor of EI was associated with WM integrity in a part of the right inferior longitudinal fasciculus (ILF). The right anterior insula is one of the important nodes of the SMC, whereas the ILF connects the visual cortex and areas related to SCN, and thus, is a part of the SCN. Our findings further support the notion that the brain regions involved in the SCN and in the SMC are associated with EI. Hum Brain Mapp, 2013. © 2011 Wiley Periodicals, Inc.
