Previous neuroimaging studies have suggested that the neural bases of trait emotional intelligence (TEI) lie in the social cognition network (SCN) and the somatic marker circuitry (SMC). The current study was the first to investigate the associations of total TEI factors and subfactors with mean diffusivity (MD) of these networks as well as regional MD of the dopaminergic system (MDDS). We found that TEI intrapersonal factor score and total TEI score were negatively correlated with regional MDDS in the vicinity of the right putamen and right pallidum and that TEI intrapersonal factor score was negatively correlated with MD values of the fusiform gyrus. Total TEI score and TEI factor scores were positively correlated with MD values of various areas within or adjacent to SCN components, SMC structures and the lateral prefrontal cortex (LPFC). Our MD findings demonstrated the importance of the dopaminergic system to TEI and implicate the SCN, SMC and LPFC in TEI. Future studies are required to investigate the implications of positive and negative associations with MD values.
先前的神经影像学研究表明，特质情绪智力（TEI）的神经基础存在于社会认知网络（SCN）和躯体标记电路（SMC）中。本研究首次探讨了总 TEI 因子和子因子与这些网络的平均扩散系数（MD）以及多巴胺能系统的区域 MD（MDDS）之间的关联。我们发现，TEI 个体因素得分和总 TEI 得分与右侧壳核和右侧苍白球附近的 MDDS 呈负相关，而 TEI 个体因素得分与梭状回的 MD 值呈负相关。总 TEI 得分和 TEI 因子得分与 SCN 成分、SMC 结构和外侧前额叶皮层（LPFC）内或附近的多个区域的 MD 值呈正相关。我们的 MD 发现表明多巴胺能系统对 TEI 的重要性，并暗示 SCN、SMC 和 LPFC 参与了 TEI。需要进一步的研究来探讨与 MD 值的正相关和负相关的意义。
