感恩是一种积极的情感特征，在获得令人满意的生活质量方面起着关键作用。然而，特质感恩与生活满意度之间关系的神经基础尚不清楚。本文研究了136名健康青年的内侧前额叶皮层（MPFC）区域灰质和白质体积（rGMV/rWMV）与感恩特质的关系，并探讨了感恩相关的大脑结构与生活满意度的关系。基于体素的形态测量分析发现，感恩特质与MPFC中涉及社会认知过程的较小rGMV和rWMV相关，这与报告感恩社会功能的行为研究结果一致。重要的是，与感恩特质相关的MPFC结构变化也显著地预测了生活满意度，并且这种关联完全由感恩特质介导。即使在调整了五大人格因素后，这些结果仍然很显著。据我们所知，这是将感恩与生活满意度联系起来的共同神经解剖学基础的第一份报告，我们的研究结果强调了MPFC是将感恩与生活满意度联系起来的重要结构。（PsycInfo数据库记录(c) 2020 APA，版权所有）
Gratitude is a positive emotional trait, and plays a pivotal role in achieving a satisfactory quality of life. However, the neural basis of the relationship between trait gratitude and life satisfaction remains unknown. Here we examined the relationship between regional gray and white matter volume (rGMV/rWMV) in the medial prefrontal cortex (MPFC) and trait gratitude, and then explored how gratitude-related brain structures are related to life satisfaction in 136 young healthy adults. Voxel-based morphometry analyses found that trait gratitude was associated with smaller rGMV and rWMV in the MPFC implicated in social-cognitive processes, consistent with the behavioral findings reporting the social functions of gratitude. Importantly, structural variations in the MPFC related to trait gratitude also significantly predicted life satisfaction, and this association was fully mediated by trait gratitude. These results were still significant even after adjusting for the Big Five personality factors. To our knowledge, this is the first report of the common neuroanatomical substrates linking trait gratitude to life satisfaction and our results highlight that the MPFC is an important structure linking trait gratitude to life satisfaction.(PsycInfo Database Record (c) 2020 APA, all rights reserved)
