In laboratory settings, creativity is measured using tasks of divergent as well as convergent thinking. It has been suggested that brain connectivity is important for creativity. In the present study, we investigated the associations of convergent thinking performance of compound Remote Associates Test (CRAT) with fractional anisotropy (FA) in diffusion tensor imaging and regional white matter (WM) volume (rWMV) in voxel-based morphometry in a large sample of healthy young adults (360 males and 280 females; mean age: 20.9 years, SD = 1.6). We showed that CRAT performance was positively correlated with WM pathway property (i.e., FA) in the left fronto-occipital fasciculus and the left inferior longitudinal fasciculus, which play important roles in processing of language and concept. Further, CRAT performance was negatively correlated with rWMV in the widespread frontal temporal subcortical and cerebellar WM areas, suggesting the unique association of convergent thinking with WM connectivity.

融合创造性思维表现与白质结构有关：来自大样本研究的证据

在实验室环境中，创造力是通过发散思维和聚合思维任务来衡量的。有人认为大脑连通性对创造力很重要。在本研究中，我们研究了复合远程关联测试 (CRAT) 的收敛思维性能与扩散张量成像中的分数各向异性 (FA) 和基于体素的形态测量学中的区域白质 (WM) 体积 (rWMV) 的关联。健康年轻人样本（360 名男性和 280 名女性；平均年龄：20.9 岁，SD = 1.6）。我们发现CRAT 表现与左额枕束和左下纵束中的WM 通路特性（即FA）呈正相关，这在语言和概念的加工中起重要作用。更多，
