Creativity is the ability to produce something novel and useful. Various tasks have been used to explore the neural bases of creativity. However, studies exploring the relationship between the brain regions during divergent thinking are still rare. Given that the brain works in networks, exploring the functional connectivity (FC) patterns during divergent thinking is important. The present study explored the FC patterns during alternative uses task and its relationship with openness to experience. Psychophysiological interaction results corroborated that the inferior parietal lobule was positively connected to the precuneus and middle temporal gyrus. Middle frontal gyrus/superior frontal gyrus was positively connected to the precuneus and supramarginal gyrus. Individual difference analysis revealed that openness to experience was positively related to the strength of FCs between some key regions of default mode, cognitive control and salience networks. Findings confirmed the network-based mechanisms underlying creativity and the neural basis of individual differences of openness to experience.
创造力是指产生新颖且有用的东西的能力。人们已经采用了各种任务来探索创造力的神经基础。然而，探索发散思维过程中大脑区域之间关系的研究仍然很少。鉴于大脑是在网络中运作的，因此探索发散思维过程中的功能连接（FC）模式很重要。本研究探索了替代用途任务过程中的 FC 模式及其与开放性体验的关系。心理生理交互作用的结果证实，顶下小叶与后扣带回和中颞叶呈正相关。中额回/额上回与后扣带回和缘上回呈正相关。个体差异分析表明，开放性体验与默认模式、认知控制和突显网络的一些关键区域之间的 FC 强度呈正相关。研究结果证实了创造力的网络机制和开放性体验个体差异的神经基础。
