What are the neuroanatomical correlates of expertise in a specific creative domain? Professional comedians, amateurs, and controls underwent a T1 MRI anatomical scan. Measures of cortical surface area (gyrification and sulcal depth) and thickness were extracted for each participant. Compared to controls, professional comedians had greater cortical surface area in the left inferior temporal gyrus, angular gyrus, precuneus, and right medial prefrontal cortex. These regions have been previously implicated in abstract, divergent thinking and the default-mode network. The high degree of overlap between the regions of greater surface area in professional comedians with the regions showing greater activation in the same group during comedy improvisation in our previous work (particularly the temporal regions and angular gyrus), suggests these regions may be specifically involved in humor creativity.

绘制“有趣的骨头”：专业喜剧演员幽默创造力的神经解剖学关联。

在特定的创意领域中，专业知识在神经解剖学上有哪些关联？专业的喜剧演员，业余爱好者和对照进行了T1 MRI解剖扫描。为每个参与者提取皮质表面积（旋转度和沟深）和厚度的量度。与对照组相比，专业喜剧演员的左颞下回，角回，前突和右前额叶皮层的皮质表面积更大。这些区域以前牵涉到抽象的，分歧的思想和默认模式网络。专业喜剧演员中较大表面积的区域之间的高度重叠，而在我们先前的工作中，即兴喜剧即兴创作中，同一组中的区域显示出更大的激活度（特别是颞部区域和角回），
