使用只读不写的繁体字和会读会写的简体字材料,以默读为实验任务,探讨＂会读会写＂与＂只读不写＂文字的加工脑区。8名在校大学生在磁共振扫描过程中默读呈现的繁体字或简体字,采用ANOVA统计全脑激活图。与简体字相比,繁体字额外激活了右额下回、左小脑。在功能连接性上,简体字和繁体字相同的激活脑区有左楔前叶-左内侧前额叶,左楔前叶-左中央前回,右枕中回-左舌回;不同的是,繁体字左楔前叶与右额下回有高相关,而简体字左楔前叶与右额中回有高相关。左内侧前额叶与中央前回只在繁体字中表现出高相关。繁体字和简体字任务的T检验差异脑区包括左颞中回和右顶下小叶。只读不写的文字具有加工的整体性和轮廓性特征,它的读音与不规则简体字相似,具有整字加工特点。繁体字和简体字加工具有相同的功能连接区,但也存在差异。右脑表现为连接脑区不同,左脑内侧前额叶与中央前回表现为相关性不同,说明内侧前额叶-中央前回在繁体字加工中起着重要作用。实验结果还证明顶叶是记忆再认的主要脑区。

The present study aims at exploring the different brain regions involved in the processing of ＂reading and writing＂ and ＂read-only＂ styles. The experimental materials are the ＂reading and writing＂ of simplified Chinese characters and the ＂read-only＂ of traditional Chinese characters that were matched in the strokes and familiarity. Eight college students were tested to read silently the simplified Chinese characters and the traditional Chinese characters during the magnetic resonance scan. the whole brain activations were acquired with ANOVA.Compared with the ＂reading and writing＂ of simplified Chinese characters, the ＂read-only＂ of traditional Chinese characters activated the right inferior frontal gyrus and the left cerebellum. The common functional connection brain regions include： the left precuneus-left medial frontal gyrus, left precuneus-left precentral gyrus and right middle occipital gyrus-left lingual gyrus. Quite contrarily, the left precuneus was related to the right precuneus in processing of traditional Chinese characters, while the left precuneus was related to the right precuneus middle frontal gyrus in processing of simplified Chinese characters. The left medial frontal gyrus and precentral gyrus showed high relativity only to traditional Chinese characters. The differences in brain areas between simplified Chinese characters and traditional Chinese characters consist of the left middle temporal gyrus and right inferior parietal lobule. The ＂read-only＂ characters are characterized by their integrity and outline, whose pronunciations characterized by integrity, are similar to the irregular simplified Chinese characters. traditional Chinese characters were less familiar to the subjects than simplified Chinese characters. Although, both traditional and simplified Chinese characters have the same functional connection area in processing, they have great difference. The differences in the right cerebral hemisphere exist in different connection area, and the differences also exist between the left medial frontal gyrus and precentral gyrus. The parietal lobe is important for the processing of recognition memory.
