长期以来，创造力一直是哲学家、心理学家和最近的神经科学家感兴趣的一个概念。最近的努力集中在认知过程可能是重要的表现在一个给定的社会背景下的新奇和实用性。其中一个认知过程-发散思维-是一个过程，通过这个过程，一个人推断出许多可能的答案，以初始刺激或目标数据集。我们试图在一组年轻（23.7 ± 4.2岁）的健康受试者中将发散思维和创造性成就（创造性成就问卷- CAQ）的成熟测量与皮质厚度联系起来。三位独立评审采用共识评估技术对每个受试者的创意产品进行排名，并从中得出“综合创意指数”（CCI）。在1.5特斯拉西门子扫描仪上获得结构磁共振成像。使用FreeSurfer图像分析套件进行皮质重建和体积分割。舌回内的一个区域与CCI呈负相关;右后扣带回与CCI呈正相关。对于CAQ，左外侧眶额容积较低与较高的创造性成就;较高的皮质厚度与右角回CAQ较高的分数有关。这是第一个将皮质厚度测量与创造力的心理测量联系起来的研究。与发散性思维和创造性成就相关的大脑区域的分布表明，对大脑区域之间信息流的认知控制可能对理解创造性认知至关重要。
Creativity has long been a construct of interest to philosophers, psychologists and, more recently, neuroscientists. Recent efforts have focused on cognitive processes likely to be important to the manifestation of novelty and usefulness within a given social context. One such cognitive process – divergent thinking – is the process by which one extrapolates many possible answers to an initial stimulus or target data set. We sought to link well established measures of divergent thinking and creative achievement (Creative Achievement Questionnaire – CAQ) to cortical thickness in a cohort of young (23.7 ± 4.2 years), healthy subjects. Three independent judges ranked the creative products of each subject using the consensual assessment technique from which a “composite creativity index” (CCI) was derived. Structural magnetic resonance imaging was obtained at 1.5 Tesla Siemens scanner. Cortical reconstruction and volumetric segmentation were performed with the FreeSurfer image analysis suite. A region within the lingual gyrus was negatively correlated with CCI; the right posterior cingulate correlated positively with the CCI. For the CAQ, lower left lateral orbitofrontal volume correlated with higher creative achievement; higher cortical thickness was related to higher scores on the CAQ in the right angular gyrus. This is the first study to link cortical thickness measures to psychometric measures of creativity. The distribution of brain regions, associated with both divergent thinking and creative achievement, suggests that cognitive control of information flow among brain areas may be critical to understanding creative cognition.
