Neural Basis of Psychological Growth following Adverse Experiences: A Resting-State Functional MRI Study

摘要: Over the past decade, research on aftereffects of stressful or traumatic events has emphasized negative outcomes from these experiences. However, positive deriving adversity are increasingly being examined, and such changes described as posttraumatic growth (PTG). To investigate relationship between basal whole-brain functional connectivity PTG, we employed resting-state magnetic resonance imaging analyzed neural networks using independent component analysis in a sample 33 healthy controls. Correlations were calculated network strength Posttraumatic Growth Inventory (PTGI) score. There associations PTGI scores brain activation rostral prefrontal cortex superior parietal lobule (SPL) within left central executive (CEN) (respectively, r = 0.41, p < 0.001; 0.49, 0.001). Individuals with higher psychological following adverse experiences had stronger prospective working memory areas function than did individuals lower (r 0.40, Moreover, found that PTG demonstrated SPL supramarginal gyrus (SMG). The SMG is one regions associated ability to reason about mental states others, otherwise known mentalizing. These findings suggest may have functions CEN social functioning SMG, their better sociality result more for mentalizing during daily interactions.
