神经科学研究已经深入地研究了隐喻理解过程中非字面语言的加工过程。然而，目前还不清楚大脑是如何创造非文字语言的。因此，本研究首次探讨了隐喻产生的神经关联。参与者通过在功能成像过程中产生新的隐喻或字面同义词来完成句子。他们在扫描仪上大声说出回答，记录下来，然后根据他们的创造性质量进行评分。我们发现，隐喻的产生与主要是左半球的大脑区域，特别是左角回，左中和上级额回（对应于左背内侧前额叶（DMPFC）皮质）和后扣带回皮质的焦点活动。此外，大脑激活在左前DMPFC和右颞中回被发现线性增加的隐喻反应的创造性质量。这些发现与隐喻理解、创造性想法产生和情景未来思维的神经科学证据有关，表明创造隐喻涉及语义记忆的灵活适应，以想象和构建新的修辞格。此外，左DMPFC可能施加执行控制，以维持战略搜索和选择，从而促进思维的创造性。第一次用功能磁共振成像研究了比喻性语言的产生。记录口头回答并分析质量。新隐喻的产生依赖于左AG和PCC的活动。左DMPFC的活动线性增加的功能隐喻的创造性。
Neuroscience research has thoroughly studied how nonliteral language is processed during metaphor comprehension. However, it is not clear how the brain actually creates nonliteral language. Therefore, the present study for the first time investigates the neural correlates of metaphor production. Participants completed sentences by generating novel metaphors or literal synonyms during functional imaging. Responses were spoken aloud in the scanner, recorded, and subsequently rated for their creative quality. We found that metaphor production was associated with focal activity in predominantly left-hemispheric brain regions, specifically the left angular gyrus, the left middle and superior frontal gyri—corresponding to the left dorsomedial prefrontal (DMPFC) cortex—and the posterior cingulate cortex. Moreover, brain activation in the left anterior DMPFC and the right middle temporal gyrus was found to linearly increase with the creative quality of metaphor responses. These findings are related to neuroscientific evidence on metaphor comprehension, creative idea generation and episodic future thought, suggesting that creating metaphors involves the flexible adaptation of semantic memory to imagine and construct novel figures of speech. Furthermore, the left DMPFC may exert executive control to maintain strategic search and selection, thus facilitating creativity of thought. Figurative language production was studied for the first time with fMRI. Verbal responses were recorded and analyzed for quality. Generation of novel metaphors relies on activity in left AG and the PCC. Activity in left DMPFC increases linearly as a function of metaphor creativity.
