摘要
目的:运用功能磁共振成像技术研究阅读不同线性词语序列的脑激活模式。方法:20名被试在磁共振扫描过程中执行视觉方式呈现词组默读,并依据线性词语序列构成的正确(语法和语义合法)和错误(语法合法,语义不合法)做出判断。结果:6种不同词语序列所激活的非共同激活区为:左侧额中回,左侧额下回,左颞上回后部,左侧丘脑,左岛叶,左侧丘脑,右侧额上回,右侧额下回,右颞上回后部,右颞下回后部,右侧中央前回,右侧中央后回,右侧丘脑。6种不同的词语序列的共同激活脑区包含左侧额上回,左侧后顶叶和右侧后顶叶。结论:语言理解功能的完成,不仅需要语言区和非语言区的脑机制相互协调,而且需要左脑和右脑相互协作。
Objective： Using the function magnetic resonance imaging to research the brain activations in reading different Chinese linear words phrases.Methods： 20 subjects were scanned in the magnetic resonance when they were reading the visual Chinese phrases.Then judgement was made in light of the constitution correctness （grammer and semantics both being correct） or in- correctness （with grammer being correct while semantics wrong） of the expressions sequence.Results： The different brain activations among the six phrases are： left middle frontal gyrus, left inferior frontal gyms, left superior temporal gyms, left thalamns, left insula, right superior frontal gyrus, right inferior frontal gyrtus, right superior temporal gyrus, right inferior temporal gyrus, right precentral gyrus and right thalamus. The same brain activations among the six phrases include left superior frontal gyms, left post parietal lobe and right post parietal lobe. Conclusion： The brain language processing not only needs the language area and the non - language area brain mechanism intercoordination but also needs the left brain and the right brain mutually co - operating together.
