尽管创造力被称为所有人力资源中最重要的，但其神经基础仍不清楚。在当前的研究中，我们使用功能磁共振成像来测量参与者解决视觉空间创造力问题的神经活动，该问题涉及发散性思维，并被认为是典型的右半球任务。正如假设的那样，与休息相比，视觉创造力任务和控制任务都激活了多个区域，包括双边后顶叶皮层和运动区域，这些区域已知参与物体的视觉空间旋转。然而，直接比较这两个任务表明，创造性任务更强烈地激活左半球区域，包括后顶叶皮层、前运动皮层、背外侧前额叶皮层（DLPFC）和内侧前额皮层。这些结果表明，即使在专门针对右半球的任务中，左半球强大的并行活动也支持创造性处理。此外，结果支持这样的观点，即高级运动规划可能是即兴创作的一般组成部分，并且这种新颖解决方案的目标导向规划可以由左 DLPFC 和内侧前额叶皮层的工作记忆处理自上而下组织。
Although creativity has been called the most important of all human resources, its neural basis is still unclear. In the current study, we used fMRI to measure neural activity in participants solving a visuospatial creativity problem that involves divergent thinking and has been considered a canonical right hemisphere task. As hypothesized, both the visual creativity task and the control task as compared to rest activated a variety of areas including the posterior parietal cortex bilaterally and motor regions, which are known to be involved in visuospatial rotation of objects. However, directly comparing the two tasks indicated that the creative task more strongly activated left hemisphere regions including the posterior parietal cortex, the premotor cortex, dorsolateral prefrontal cortex (DLPFC) and the medial PFC. These results demonstrate that even in a task that is specialized to the right hemisphere, robust parallel activity in the left hemisphere supports creative processing. Furthermore, the results support the notion that higher motor planning may be a general component of creative improvisation and that such goal-directed planning of novel solutions may be organized top-down by the left DLPFC and by working memory processing in the medial prefrontal cortex.
