What are the neural correlates of insight solutions? To explore this question we asked participants to perform an anagram task while in the fMRI scanner. Previous research indicates that anagrams are unique in that they can yield both insight and search solutions in expert subjects. Using a single-trial fMRI paradigm, we utilized the anagram methodology to explore the neural correlates of insight versus search solutions. We used both reaction time measures and subjective reports to classify each trial as a search or insight solution. Data indicate that verbal insight solutions activate a distributed neural network that includes bilateral activation in the insula, the right prefrontal cortex, and the anterior cingulate. These areas are discussed with their possible role in evaluation and metacognition of insight solutions, as well as attention and monitoring during insight.
顿悟解决方案的神经关联是什么？为了探究这个问题，我们让参与者在功能磁共振成像扫描仪中执行一个字谜任务。先前的研究表明，字谜的独特之处在于它们在专家受试者中既能产生顿悟解决方案，也能产生搜索解决方案。使用单试次功能磁共振成像范式，我们利用字谜方法来探究顿悟解决方案与搜索解决方案的神经关联。我们使用反应时间测量和主观报告将每个试次分类为搜索或顿悟解决方案。数据表明，言语顿悟解决方案激活了一个分布式神经网络，该网络包括脑岛、右侧前额叶皮层和前扣带回的双侧激活。将讨论这些区域在顿悟解决方案的评估和元认知中的可能作用，以及顿悟过程中的注意力和监测。
