Creativity relies on the reorganizing of multimodal information and flexible switching between different modes of thinking, suggesting an association between creativity and the reconfiguration of functional brain networks. Here, we investigated global and regional brain dynamics in high-creative (HCG, N = 22) and a low-creative (LCG, N = 20) groups during a divergent creative thinking task. We found that during the creative thinking task, the HCG demonstrated higher global network flexibility, as compared to the LCG. In addition, creative thinking in the HCG was associated with significantly higher regional flexibility in the medial superior temporal gyrus, superior parietal lobule, precuneus, nucleus accumbens, and the ventral inferior frontal gyrus. Interestingly, the LCG demonstrated decreased regional flexibility in the medial superior temporal gyrus, superior parietal lobule, and the ventral inferior frontal gyrus. We also found that the changes in global and regional flexibility in the creative compared with the control tasks were good features allowing for distinguishing between the HCG and the LCG. Taken together, these findings provide evidence that divergent creative thinking is associated with flexible reconfiguration of brain networks involved in verbal, working memory, and reward processing.
创造力依赖于多模态信息的重新组织和不同思维模式之间的灵活转换，这表明创造力与功能大脑网络的重新配置之间存在关联。在这里，我们在一项发散性创造性思维任务中研究了高创造性（HCG，N=22）和低创造性（LCG，N=20）组的全局和区域大脑动力学。我们发现，在创造性思维任务中，HCG 表现出比 LCG 更高的全局网络灵活性。此外，HCG 的创造性思维与内侧上颞叶、顶叶上回、楔前叶、伏隔核和腹侧下额叶的区域灵活性显著相关。有趣的是，LCG 在内侧上颞叶、顶叶上回和腹侧下额叶的区域灵活性降低。我们还发现，与控制任务相比，创造性任务中全局和区域灵活性的变化是区分 HCG 和 LCG 的良好特征。总之，这些发现提供了证据，表明发散性创造性思维与涉及语言、工作记忆和奖励处理的大脑网络的灵活重新配置有关。
