    AbstractCreativity is imperative to the progression of civilization and is central to cultural life. Many neuroimaging studies have investigated the patterns of functional activity in the brain during different creative tasks, and the structural and functional characteristics of the highly creative individuals. However, few studies have investigated resting-state functional connectivity (RSFC) in the brain related to individual differences in creativity, and it is still unclear whether the RSFC underlying creativity can be changed by training. The present study therefore used resting-state functional magnetic resonance imaging (Rs-fMRI) to investigate the relationship between RSFC and creativity (divergent thinking, measured by the Torrance Tests of Creative Thinking) to explore whether RSFC can be influenced by cognitive stimulation. The results of 269 adults showed that creativity was positively correlated with the strength of RSFC between the medial prefrontal cortex (mPFC) and the middle temporal gyrus (mTG). In addition, behavioral data showed that cognitive stimulation was successful in enhancing originality in a subset of the original participants (n = 34). Most interesting, we found that there was also a significantly increased RSFC between the mPFC and the mTG by analyzing the data of Rs-fMRI after creativity training. Taken together, these results suggest that increased RSFC between mPFC and mTG, which belong to the default mode network might be crucial to creativity, and that RSFC between the mPFC and mTG can be improved by means of cognitive stimulation (reflecting creativity training-induced changes in functional connectivity, especially in the lower creativity individuals who had lower scores of Torrance Tests of Creative Thinking).
