基于大脑的证据表明大脑的额极对于类比映射很重要。另外，认知研究已将语义距离确定为类比映射创造力的关键决定因素（即，距离越远的类比通常更具创造性）。在这里，我们使用功能磁共振成像来评估类比生成任务期间的大脑活动，在该任务中我们改变了类比映射的语义距离（从潜在语义分析中定量得出）。数据表明，即使在消除任务难度的影响之后，左额极皮层先验感兴趣区域内的活动也随着语义距离的增加而呈参数共变。结果表明，额极皮层的招募增加是整合语义遥远信息以生成创造性类比推理解决方案的机制。
Brain-based evidence has implicated the frontal pole of the brain as important for analogical mapping. Separately, cognitive research has identified semantic distance as a key determinant of the creativity of analogical mapping (i.e., more distant analogies are generally more creative). Here, we used functional magnetic resonance imaging to assess brain activity during an analogy generation task in which we varied the semantic distance of analogical mapping (as derived quantitatively from a latent semantic analysis). Data indicated that activity within an a priori region of interest in left frontopolar cortex covaried parametrically with increasing semantic distance, even after removing effects of task difficulty. Results implicate increased recruitment of frontopolar cortex as a mechanism for integrating semantically distant information to generate solutions in creative analogical reasoning.
