学术背景:语义的加工机制是认知神经科学关注的焦点问题之,随着研究技术手段的不断创新和多样化,使得与语义加工的相关脑区及其各脑区的神经机制逐渐清晰。但是,目前有关汉语的语义加工机制的研究力度仍然不够,对于操汉语者所持有的汉语语义加工的脑神经机制的研究有待于进一步深化。 目的:通过对操汉语者言语障碍的语义加工与相关脑区功能关系的研究成果的归纳,并对其相关的大脑神经机制与语义加工网络涉及的脑的局部系统及其功能与脑空间机构进行分析,进一步明确基础神经心理学对临床诊断,治疗及康复的意义。 检索策略:作者对1984年至今的相关文献进行检索,关键词为“semanticprocessing”,并限定文献语言为英文。检索的数据库主要有中国知网(CNKI)中国期刊全文数据库1994-01,2006-05、荷兰Elsevier公司期刊数据库1984-01,2006-05和美国EBSCOhost数据库1984-01,2006-05中AcademicSourcePremier和MEDLINE两个子数据库,同时手工检索与之内容相关的书籍。检索到文章264篇,纳入关于语义加工与脑区功能联系的43篇,并结合有关论著进行总结,排除联系不密切的文献,对于未发表的文章仅做参考使用。 文献评价:文献来源于论著、汇总分析、个例报告、研究性报告。评价人为相关领域研究人员。 资料综合:汉语语义加工的相关脑区主要涉及左侧颞上回、颞中回、颞叶前部、额下回以及左额叶中部,组成额-颞工作网共同支持语义加工,其中左侧颞上回后部和颞中回与语义加工关系最密切,涉及到语义的一般存储和自动加工,颞叶前部则与不同语义的整合加工有关;额下回与控制、执行加工,短时记忆加工有关联;左额叶中部是近年来发现的与汉语语义加工关系较大的脑区部位,现有的推论是汉字特有的字形结构的加?
BAEKGROUND:The brain mechanism of semantic processing is one of the focus problems in cognitive neuroscience. With the research technologies plentiful and diversified, the brain mechanism of semantic processing is gradually distinct. However, at present, the related researches on Chinese semantic processing are not enough. The brain mechanism of semantic processing by Chinese language obstacle should be studied more deeply. OBJECTIVE: To further identify the neuropsychological significance of clinical diagnosis, treatment and rehabilitation by concluding the study fruits on the brain mechanism of semantic processing by native Chinese speaker with dysphonia and analyze the relationship between the related brain mechanism and the local brain system of semantic processes as well as brain anatomical parts. RETRIEVE STRATEGY: The retrieve staffs are the research personnel for this paper. The range of retrieve time focuses since 1984. A computer-based online search was conducted in CNKI for literatures related to basic neuropsychology and its clinical application published between January 1994 and May 2006, in Elsevier for articles between January 1984 and May 2006, in Academic Source Premier and MEDLINE of EBSCOhost for studies between January 1984 and May 2006 with the key words of "semantic processing", and the language was limited to English. Meanwhile, relevant data were searched manually. The number of total retrieved articles was 264, among which 43 enrolled studies were in accordance with the inclusion criteria and excluded articles involving semantic processing or encephalic region but without their relationship. The unpublished articles were only used for references. LITERATURE EVALUATION: The literatures are selected from related works, collected analyses, reports from single case or research. Evaluated persons are related research staffs. DATA SYNTHESIS : Processing of Chinese semantic relied primarily on the left superior temporal region, middle temporal gyrus, the infedor gyrus of fronta
