创造力的脑结构与脑功能基础

Neural Basis of Creativity:Evidence From Structural and Functional Imaging

从脑结构和脑功能两方面对创造力的脑神经基础进行了评述。就创造力的脑结构而言,尸体脑解剖研究表明创造力可能与顶叶与角回有关;活体脑结构成像研究则显示,创造力主要与额叶、扣带回以及皮下白质或灰质浓度有关。就创造力的脑功能而言,任务取向研究表明创造力任务主要激活了额叶和顶叶及少数其他皮层区域;而个体差异取向研究则表明创造力被试激活了右侧额叶、大脑皮层以及小脑的某些区域。未来研究需在加强脑结构影像研究基础上,注重从被试抽样和筛选等方面细化任务模式和个体差异模式的创造力研究,以获得更一致的结果。

The study mainly focused on the neural basis of creativity, which based on brain structural and fimetional imaging studies. Evidence from brain anatomy indicated that creativity may be related to parietal and angular gyrus. However, vivo brain structural imaging researches showed that creativity mainly relative to frontal gyrus and cingulate cortex and the subcutaneous concentration of white or gray matter. Task-oriented studies found that the frontal and parietal cortex, even combining with some other areas play an important role in creativity, whereas the right frontal lobe as well as some brain regions in cerebral cortex and cerebellum activated in individual difference approach. In order to get more consistent conclusions, studies in the future should investigate creativity systematically and integrally, and also design more comparable experiments and creativity tasks to detect creativity by our high temporal and high spatial solutions technologies.
