一个笑话的理解依赖于大脑多个区域的语义、助记、推理和情感贡献。解剖受限脑磁图(AMEG)结合了高密度全头脑磁图和解剖磁共振成像，使我们能够估计特定于幽默的大脑活动发生在哪里，并了解它们的时间序列。妙语对笑话问题的回答要么好笑，要么不好笑(语义上一致)，要么荒谬(不一致)。健康的受试者对他们的评分是有趣还是不有趣。正如预期的那样，由于整合困难，不协调的结尾在左侧占优势的颞额前区引起了最大的N400米。相比之下，有趣的笑点在最初的词汇-语义阶段唤起了最小的N400m，这与它们与设置问题的“表面一致性”是一致的。由于大脑前内侧前额叶皮质对歧义的敏感性，它可能参与了随后的“第二次拍摄”加工，对于笑话来说，这大概反映了在有趣的笑点中发现了一个聪明的“转折”。笑话选择活动同时出现在右侧前额叶皮质，这可能导致扩展的双边颞额网络在笑点和设置之间建立起遥远的意想不到的创造性连贯性。这种从最初有希望但具有误导性的左额-颞区整合，到内侧前额叶模糊评估和右侧前额叶再加工的过程，可能反映了幽默背后的本质张力和解决方案。
Understanding a joke relies on semantic, mnemonic, inferential, and emotional contributions from multiple brain areas. Anatomically constrained magnetoencephalography (aMEG) combining high-density whole-head MEG with anatomical magnetic resonance imaging allowed us to estimate where the humor-specific brain activations occur and to understand their temporal sequence. Punch lines provided either funny, not funny (semantically congruent), or nonsensical (incongruent) replies to joke questions. Healthy subjects rated them as being funny or not funny. As expected, incongruous endings evoke the largest N400m in left-dominant temporo-prefrontal areas, due to integration difficulty. In contrast, funny punch lines evoke the smallest N400m during this initial lexical–semantic stage, consistent with their primed “surface congruity” with the setup question. In line with its sensitivity to ambiguity, the anteromedial prefrontal cortex may contribute to the subsequent “second take” processing, which, for jokes, presumably reflects detection of a clever “twist” contained in the funny punch lines. Joke-selective activity simultaneously emerges in the right prefrontal cortex, which may lead an extended bilateral temporo-frontal network in establishing the distant unexpected creative coherence between the punch line and the setup. This progression from an initially promising but misleading integration from left frontotemporal associations, to medial prefrontal ambiguity evaluation and right prefrontal reprocessing, may reflect the essential tension and resolution underlying humor.
