      structural variations in the medial prefrontal cortex and life satisfaction.

AB  - 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
