Neurobiology of the reading system

前颞叶（anterior temporal lobes，ATLs）在异常词（如"yatch"和"colonel"）的阅读中的作用一直是语言神经生物学领域激烈争论的主题。这种模糊主要是因为患者数据和健康受试者的神经影像学研究提供了相互矛盾的结果。患者数据一致地表明，阅读异常词的能力是由语义记忆系统介导的（即，负责概念性知识的记忆系统）并且与前颞叶的完整性相关联。然而，对健康受试者的功能成像研究未能证实这些发现，并显示在异常词阅读过程中没有显着的ATL激活。

The role of the anterior temporal lobes (ATLs) in the reading of exception words (i.e. words with atypical spelling-to-sound correspondence, such as 'yatch' and 'colonel') has been subject of intense debate in the field of neurobiology of language. This obscurity remains primarily because patient data and neuroimaging studies on healthy subjects have provided contradictory results. Patient data have consistently shown that the ability to read exception words is mediated by the semantic memory system (i.e., the memory system that is responsible for conceptual knowledge) and is associated with the integrity of the anterior temporal lobes. However, functional imaging studies on healthy subjects have failed to confirm these findings and have shown no significant ATL activation during exception word reading.
