中文摘要：

人类的语言功能不仅仅基于以额叶、颞叶为代表的语言脑区灰质皮层的激活,更重要的是基于这些脑区之间白质纤维束的连接。随着各种脑成像技术的逐渐成熟,基于核磁共振的弥散张量成像技术在语言认知领域展现出越来越重要的作用。弥散张量成像在语言认知研究上的应用,可以将其与行为测查、功能定位成像、功能连接、全脑网络等多种分析方法结合来共同研究语言认知,进而从脑结构的角度来探究语言与脑的关系。

英文摘要：

The achievement of human language function is not only based on the brain regions in frontal and temporal cortex which are activated by language tasks, but also based on the anatomical connectivity of white matter fibers between these regions. With the development of technique of neural image, the diffusion tensor magnetic resonance image has been playing more and more important role in the research of the neural mechanism of language. We can apply diffusion tensor image to study the neural mechanism of language via combining diffusion tensor image with other approaches such as behavioral method, functional localization, functional connectivity and whole brain network analysis. Moreover the valid anatomical evidences for the neural substrate of language provided by diffusion tensor image will increase our understanding the relationship of brain and language.
