日常生活中的语言理解需要将先前的话语语境和一般世界知识与当前的话语或句子不断整合。在神经语言学文献中，这些所谓的情境模型构建过程被认为是由前额叶皮层或右半球负责的。在这项研究中，我们使用全脑事件相关功能磁共振成像直接映射的神经相关的叙事理解的背景。在使用自旋回波序列进行扫描时，20名参与者听了32个短篇故事，其中一半包含全球不一致的信息。这些不一致之处要么是时间或年代信息的一致性，要么是主人公的情感状态。听到一个不一致的词会激活右前颞叶。不同的信息方面的比较显示激活左侧楔前叶和双边额顶叶网络的时序信息。情绪信息引起腹内侧前额叶皮层和扩展杏仁复合体的激活。此外，不一致的情绪信息的整合涉及背侧前内侧皮层（布罗德曼8/9区），而不一致的时间信息的整合需要两侧的外侧前额叶皮层。这些结果表明，听故事可以引起激活反映内容特定的过程。此外，情境模型的更新不是一个单一的过程，而是取决于文本的特定要求。右半球在语境中对语言处理有贡献，但同样重要的是左内侧和双侧前额叶皮质。
Language comprehension in everyday life requires the continuous integration of prior discourse context and general world knowledge with the current utterance or sentence. In the neurolinguistic literature, these so-called situation model building processes have been ascribed to the prefrontal cortex or to the right hemisphere. In this study, we use whole-head event-related fMRI to directly map the neural correlates of narrative comprehension in context. While being scanned using a spin-echo sequence, 20 participants listened to 32 short stories, half of which contained globally inconsistent information. The inconsistencies concerned either consistent temporal or chronological information or the emotional status of the protagonist. Hearing an inconsistent word elicited activation in the right anterior temporal lobe. The comparison of different information aspects revealed activation in the left precuneus and a bilateral frontoparietal network for chronological information. Emotional information elicited activation in the ventromedial prefrontal cortex and the extended amygdaloid complex. In addition, the integration of inconsistent emotional information engaged the dorsal frontomedial cortex (Brodmann's area 8/9), whereas the integration of inconsistent temporal information required the lateral prefrontal cortex bilaterally. These results indicate that listening to stories can elicit activation reflecting content-specific processes. Furthermore, updating of the situation model is not a unitary process but it also depends on the particular requirements of the text. The right hemisphere contributes to language processing in context, but equally important are the left medial and bilateral prefrontal cortices.
