Whether creativity is a domain-general or domain-specific ability has been a topic of intense speculation. Although previous studies have examined domain-specific mechanisms of creative performance, little is known about commonalities and distinctions in neural correlates across different domains. We applied activation likelihood estimation (ALE) meta-analysis to identify the brain activation of domain-mechanisms by synthesizing functional neuroimaging studies across three forms of artistic creativity: music improvisation, drawing, and literary creativity. ALE meta-analysis yielded a domain-general pattern across three artistic forms, with overlapping clusters in the presupplementary motor area (pre-SMA), left dorsolateral prefrontal cortex, and right inferior frontal gyrus (IFG). Regarding domain-specificity, musical creativity was associated with recruitment of the SMA-proper, bilateral IFG, left precentral gyrus, and left middle frontal gyrus (MFG) compared to the other two artistic forms; drawing creativity recruited the left fusiform gyrus, left precuneus, right parahippocampal gyrus, and right MFG compared to musical creativity; and literary creativity recruited the left angular gyrus and right lingual gyrus compared to musical creativity. Contrasting drawing and literary creativity revealed no significant differences in neural activation, suggesting that these domains may rely on a common neurocognitive system. Overall, these findings reveal a central, domain-general system for artistic creativity, but with each domain relying to some degree on domain-specific neural circuits.
创造力是一种领域一般性还是领域特殊性能力一直是激烈猜测的话题。尽管先前的研究已经检验了创造性表现的领域特异性机制，但对于不同领域的神经相关性的共性和区别知之甚少。我们应用激活似然估计（ALE）元分析来通过综合三个艺术创作形式（音乐即兴创作、绘画和文学创作）的功能神经影像学研究，来确定领域机制的大脑激活。ALE 元分析产生了一种跨三种艺术形式的领域一般性模式，在前运动辅助区（pre-SMA）、左背外侧前额叶皮层和右额下回（IFG）中存在重叠的集群。关于领域特异性，与其他两种艺术形式相比，音乐创作与 SMA-proper、双侧 IFG、左中央前回和左额中回（MFG）的募集有关；与音乐创作相比，绘画创作募集了左梭状回、左楔前叶、右海马旁回和右 MFG；与音乐创作相比，文学创作募集了左角回和右舌回。对比绘画和文学创作，在神经激活方面没有发现显著差异，这表明这些领域可能依赖于共同的神经认知系统。总的来说，这些发现揭示了艺术创造力的一个中心、领域一般性系统，但每个领域都在某种程度上依赖于领域特异性的神经回路。
