Gender differences in creativity partly underscore the diversity between males and females in society. Divergent thinking forms the core of creativity and enables humans to innovate and solve problems. Sex differences in functional activation associated with divergent thinking may reflect the use of distinct strategies in males and females when faced with tasks involving creativity. Although female-specific white matter associated to creativity has been found, fractional anisotropy measuring structural connectivity which can better reflect the degree of brain regions interplay should be adapted to corroborate sex-specific WM connectivity related to divergent thinking. Using fractional anisotropy indexes derived from diffusion tensor imaging in 425 participants (118 males), we observed that divergent thinking was positively associated with fractional anisotropy in the corpus callosum and right superior longitudinal fasciculus in females and was positively associated with fractional anisotropy in the right tapetum in males. Our findings provide insight into sex-specific intra- and inter-hemispheric structural connectivity bases underlying divergent thinking.
性别差异在一定程度上凸显了社会中男性和女性之间的多样性。发散思维是创造力的核心，使人类能够创新和解决问题。与发散思维相关的功能激活的性别差异可能反映了男性和女性在面对涉及创造力的任务时使用不同的策略。尽管已经发现了与创造力相关的女性特有的白质，但分数各向异性测量结构连接性可以更好地反映大脑区域相互作用的程度，应该采用来证实与发散思维相关的特定于性别的 WM 连接性。我们使用来自 425 名参与者（118 名男性）的扩散张量成像的分数各向异性指数，发现女性的发散思维与胼胝体和右侧上纵束的分数各向异性呈正相关，而男性的发散思维与右侧丘脑的分数各向异性呈正相关。我们的研究结果为发散思维的特定于性别的半球内和半球间结构连接基础提供了深入了解。
