在这项研究中，激活似然估计(ALE)元分析被用来对发散思维的神经成像研究进行定量研究。基于ALE结果，功能磁共振成像(FMRI)研究表明，发散性思维任务(DTT)下的分布式脑区比对照任务下更活跃，但大部分脑区失活。ALE结果表明，DTTS创造性想法产生的脑网络可能由外侧前额叶、顶后[如顶下小叶(BA40)和楔前(BA7)]、前扣带回(BA32)和颞叶的多个区域[如左侧颞中回(BA39)和左侧梭形回(BA37)]组成。左侧背外侧前额叶皮质(BA46)与选择联系松散和遥远的概念并将其组织成创造性想法有关，而ACC(BA32)与观察和形成远距离语义联系有关。顶叶后皮质可能参与了与创造性思维提取和缓冲相关的语义信息，而颞叶皮质的几个区域可能与储存的长期记忆有关。此外，结构研究的ALE结果表明，发散思维与多巴胺能系统(如左侧尾状核和屏状核)有关。基于ALE结果，功能磁共振成像和结构磁共振成像研究都可以从不同的方面(如特定的认知加工和稳定的认知能力个体差异)揭示发散思维的神经基础。Hum Brain Mapp 36：2703-2718,2015。©2015 Wiley期刊，Inc.
In this study, an activation likelihood estimation (ALE) meta‐analysis was used to conduct a quantitative investigation of neuroimaging studies on divergent thinking. Based on the ALE results, the functional magnetic resonance imaging (fMRI) studies showed that distributed brain regions were more active under divergent thinking tasks (DTTs) than those under control tasks, but a large portion of the brain regions were deactivated. The ALE results indicated that the brain networks of the creative idea generation in DTTs may be composed of the lateral prefrontal cortex, posterior parietal cortex [such as the inferior parietal lobule (BA 40) and precuneus (BA 7)], anterior cingulate cortex (ACC) (BA 32), and several regions in the temporal cortex [such as the left middle temporal gyrus (BA 39), and left fusiform gyrus (BA 37)]. The left dorsolateral prefrontal cortex (BA 46) was related to selecting the loosely and remotely associated concepts and organizing them into creative ideas, whereas the ACC (BA 32) was related to observing and forming distant semantic associations in performing DTTs. The posterior parietal cortex may be involved in the semantic information related to the retrieval and buffering of the formed creative ideas, and several regions in the temporal cortex may be related to the stored long‐term memory. In addition, the ALE results of the structural studies showed that divergent thinking was related to the dopaminergic system (e.g., left caudate and claustrum). Based on the ALE results, both fMRI and structural MRI studies could uncover the neural basis of divergent thinking from different aspects (e.g., specific cognitive processing and stable individual difference of cognitive capability).
