随着计机算体层摄影(CT)技术的临床应用,对病变的定位、性质和进行动态观察成为可能,为研究CVD后失语和言语障碍有了可靠的理论依据。所谓失语,是指大脑损伤和对语言的理解和表达能力的缺失。本文拟对语言的中枢定位,语言障碍特点及分类作以概述: 一言语中枢定位关于语言的解剖学定位,早在十九世纪初就开始了广泛的研究。后来,Broca和Wernicke又具体地证明了生成或发出言语
With the clinical application of computerized computed tomography (CT) technique, it is possible to locate, characterize and make dynamic observation of lesions, and provide a reliable theoretical basis for studying aphasia and speech disorders after CVD. The so-called aphasia refers to the brain damage and lack of understanding and expression of language. This article is intended to outline the central localization of language, the characteristics and classification of language barriers: a central position of speech Anatomy of the language, as early as the beginning of the nineteenth century began a wide range of research.
