The aim of the present study was to explore brain activities associated with creativity and expertise in literary writing. Using functional magnetic resonance imaging (fMRI), we applied a real-life neuroscientific setting that consisted of different writing phases (brainstorming and creative writing; reading and copying as control conditions) to well-selected expert writers and to an inexperienced control group. During creative writing, experts showed cerebral activation in a predominantly left-hemispheric fronto-parieto-temporal network. When compared to inexperienced writers, experts showed increased left caudate nucleus and left dorsolateral and superior medial prefrontal cortex activation. In contrast, less experienced participants recruited increasingly bilateral visual areas. During creative writing activation in the right cuneus showed positive association with the creativity index in expert writers. High experience in creative writing seems to be associated with a network of prefrontal (mPFC and DLPFC) and basal ganglia (caudate) activation. In addition, our findings suggest that high verbal creativity specific to literary writing increases activation in the right cuneus associated with increased resources obtained for reading processes.
本研究的目的是探索与文学创作中的创造力和专业技能相关的大脑活动。我们使用功能磁共振成像（fMRI），将一个由不同写作阶段（头脑风暴和创意写作；阅读和抄写作为对照条件）组成的现实神经科学环境应用于精心挑选的专家作家和一个无经验的对照组。在创意写作过程中，专家们在主要为左半球的额顶颞网络中表现出大脑激活。与无经验的作家相比，专家们左尾状核以及左背外侧和额内侧前额叶皮质的激活增加。相比之下，经验较少的参与者双侧视觉区域的激活越来越多。在创意写作过程中，右侧楔叶的激活与专家作家的创造力指数呈正相关。在创意写作方面的高经验似乎与前额叶（内侧前额叶皮质和背外侧前额叶皮质）和基底神经节（尾状核）激活的网络有关。此外，我们的研究结果表明，文学写作特有的高语言创造力会增加右侧楔叶的激活，这与阅读过程中获得的资源增加有关。
