摘要
目的:回顾经颅磁刺激(transcranialmagneticstimulation,TMS)应用于语言神经加工处理过程的研究结果,探讨TMS是否可以作为研究语言神经加工处理过程的一种有效方法。资料来源:应用计算机检索Medline1985-01/2004-01与TMS相关文章,并手工检索(6种以上国外期刊),检索词为“transcranialmagneticstimulation,languageorspeech,并限定文章语言种类为English。同时应用计算机检索万方数据库2002-01/2004-08相关文章,检索词为“经颅磁刺激,大脑的可塑性”,并限定文章语言种类为中文。资料选择:选择TMS应用于语言神经加工处理过程研究方面的文献,排除科研设计明显不正确的文献及综述文献。资料提炼:对检索到的TMS应用于语言神经加工处理过程研究方面文章中的相关信息进行综述。资料综合:对检索到的文章进行分析综合,其中提示语言神经加工处理是一个非常复杂的过程,它包括阅读、书写、命名和语义等许多特殊组成成分,TMS能引起给定皮质区短暂的功能改变,可影响语言进程中的某一特定过程。结论:TMS是研究语言神经加工处理过程的一种新的有效方法,但利用TMS研究语言形成过程的具体机制尚需更深入的探讨。
OBJECTIVE:To review the results of study on the application of transcranial ma gnetic stimulation(TMS) in neural language processing,and investigate whether TM S can be used as an effective method for study of neural language processing. DATA SOURCES:An online search of Medline database was undertaken to identify a rticles about TMS published from January 1985 to January 2004,besides more than 6 kinds of journals abroad were searched manually,the keywords were “transcrani al magnetic stimulation,language or speech' with language limited to English. Me anwhile,relevant Chinese articles were searched in Wanfang database with compute r by using the keywords of “transcranial magnetic stimulation, plasticity of th e brain' published between January 2001 and August 2004. STUDY SELECTION:Papers about the application of TMS in neural language process ing were selected,while those with obvious incorrect scientific research design and the reviews were excluded. DATA EXTRACTION:Relevant information in the articles about the application of TMS in neural language processing was reviewed. DATA SYNTHESIS:The collected papers were analyzed and synthesized,and it was s uggested that the linguistic processing was very complex,and the language proces sing was composed by a lot of components such as reading,handwriting,naming,synt ax and so on.TMS could cause the transient functional changes in the region of c ortex,which can influence the special ongoing neural language processing during linguistic processing. CONCLUSION:TMS is a new and promising tool for investigating neural language p rocessing.But how to study the precise mechanism of the linguistic processing by TMS may require further development.
