人们有时会用一种叫做洞察力的独特过程来解决问题，伴随着“啊哈！”的体验。长期以来，人们一直不清楚是不同的认知和神经过程导致了洞察力和非洞察力的解决方案，还是解决方案只是在随后的主观感觉上有所不同。最近的行为研究表明了不同的表现模式，并提出了顿悟和非顿悟解决方案的不同半球参与。受试者解决了口头问题，并在每次正确解决后指出他们是否有洞察力。我们观察到洞察力的两个客观的神经关联。功能性磁共振成像（实验1）显示，与非顿觉解决方案相比，顿觉解决方案右半球颞前上回的活动增加。在最初的解决努力中，同一区域是活跃的。头皮脑电图记录（实验2）显示，在洞察力解决方案出现前0.3秒，同一区域的高频（γ波段）神经活动突然爆发。在理解过程中，右前颞区与建立远相关信息之间的联系有关。尽管所有问题的解决都依赖于一个很大程度上共享的皮层网络，但当解决者参与不同的神经和认知过程时，顿悟就会突然闪现，这些过程使他们看到了以前无法发现的联系。功能磁共振成像（fMRI）和脑电图（EEG）用于研究受试者在口头任务期间的神经活动，受试者报告通过洞察力获得的解决方案
People sometimes solve problems with a unique process called insight, accompanied by an “Aha!” experience. It has long been unclear whether different cognitive and neural processes lead to insight versus noninsight solutions, or if solutions differ only in subsequent subjective feeling. Recent behavioral studies indicate distinct patterns of performance and suggest differential hemispheric involvement for insight and noninsight solutions. Subjects solved verbal problems, and after each correct solution indicated whether they solved with or without insight. We observed two objective neural correlates of insight. Functional magnetic resonance imaging (Experiment 1) revealed increased activity in the right hemisphere anterior superior temporal gyrus for insight relative to noninsight solutions. The same region was active during initial solving efforts. Scalp electroencephalogram recordings (Experiment 2) revealed a sudden burst of high-frequency (gamma-band) neural activity in the same area beginning 0.3 s prior to insight solutions. This right anterior temporal area is associated with making connections across distantly related information during comprehension. Although all problem solving relies on a largely shared cortical network, the sudden flash of insight occurs when solvers engage distinct neural and cognitive processes that allow them to see connections that previously eluded them. Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are used to study neural activity in subjects during a verbal task for which they report solutions achieved by insight
