Psychological resilience is characterized as the ability to recover from stress, which is essential for sleep quality. However, the neurological underpinnings of psychological resilience and the neural substrates of the links between psychological resilience and sleep quality in healthy brains remain not well understood. To address these issues, we adopted the method of resting-state functional connectivity (rs-FC) analysis in 144 young college students. The functional connectivity analysis indicated that psychological resilience was associated with the middle frontal gryus (MFG) functional connectivity, which mainly involved the right middle cingulum gyrus (rMCG), the right precentral gyrus (rPreCG), the left postcentral gyrus (lPoCG), and the left thalamus. Furthermore, mediation analysis suggested that psychological resilience played a mediating role in the relationship between MFG functional connectivity and sleep quality. Overall, the current study offered further evidence for the neurological underpinnings of psychological resilience and provided new insights into the relationship between psychological resilience and sleep quality from a neural basis perspective.
心理韧性的特点是从压力中恢复的能力，这对睡眠质量至关重要。然而，心理韧性的神经学基础以及健康大脑中心理韧性与睡眠质量之间联系的神经基质仍未得到很好的理解。为了解决这些问题，我们对144名年轻大学生采用了静息态功能连接（rs-FC）分析方法。功能连接分析表明，心理韧性与额中回（MFG）功能连接有关，主要涉及右侧中央旁回（rMCG）、右侧中央前回（rPreCG）、左侧中央后回（lPoCG）和左侧丘脑。此外，中介分析表明，心理韧性在MFG功能连接与睡眠质量之间的关系中起中介作用。总体而言，当前研究为心理韧性的神经学基础提供了进一步的证据，并从神经基础的角度为心理韧性与睡眠质量之间的关系提供了新的见解。
