Personality traits refer to a set of independent patterns of behaviour, cognition, and emotion. The Big-Five of Personality (NEO-FFI), is one of the most generally recognized taxonomies of personality. The current structural and functional correlates of personality are divergent and inconsistent in some cases, which necessitate further investigation of it. Herein, we aimed to investigate the white matter (WM) microstructural correlates of personality traits using diffusion MRI connectometry. Overall, the main findings of this study were located in different parts of the corpus callosum (CC) and middle cerebellar peduncle (MCP), highlighting the significant role of WM local connectome in the CC and MCP in the regulation of personality traits. Future studies need to validate our results.

人格特质是指行为，认知和情感的一系列独立模式。人格五分法（NEO-FFI）是最普遍认可的人格分类法之一。当前人格的结构和功能相关性在某些情况下是分散的和不一致的，因此有必要对其进行进一步的研究。在本文中，我们旨在研究使用弥散核磁共振成像连接法的人格特质的白质（WM）微结构相关性。总体而言，这项研究的主要发现位于call体（CC）和中小脑梗（MCP）的不同部分，突出了WM局部连接体在CC和MCP在性格特征调节中的重要作用。未来的研究需要验证我们的结果。
