本研究的目的是确定区域结构的差异，母语为声调的语言（中国）相比，非声调（欧洲）的语言发言者的大脑。我们的期望是，在音高感知和产生方面会有不同的区域。因此，我们比较了三组参与者的大脑结构图像：31名母语为汉语的人; 7名母语为英语的人，他们在成年后学习了汉语;以及21名不会说汉语的欧洲多语者。结果发现，在右前颞叶和左前颞叶附近的两个大脑区域，与不说汉语的人相比，说汉语的人的灰色和白色物质密度明显更大。重要的是，在母语为汉语的人和将汉语作为非母语学习的欧洲受试者中都发现了这种效应，这表明它们与语言相关，而不是种族效应。在以前的研究的基础上，我们认为，这些灰色和白色物质的变化在一个音调语言的扬声器的位置是一致的，在链接的音高的话，他们的意思的作用。《大脑地图》，2009年。© 2009 Wiley利斯公司
The aim of this study was to identify regional structural differences in the brains of native speakers of a tonal language (Chinese) compared to nontonal (European) language speakers. Our expectation was that there would be differences in regions implicated in pitch perception and production. We therefore compared structural brain images in three groups of participants: 31 who were native Chinese speakers; 7 who were native English speakers who had learnt Chinese in adulthood; and 21 European multilinguals who did not speak Chinese. The results identified two brain regions in the vicinity of the right anterior temporal lobe and the left insula where speakers of Chinese had significantly greater gray and white matter density compared with those who did not speak Chinese. Importantly, the effects were found in both native Chinese speakers and European subjects who learnt Chinese as a non‐native language, illustrating that they were language related and not ethnicity effects. On the basis of prior studies, we suggest that the locations of these gray and white matter changes in speakers of a tonal language are consistent with a role in linking the pitch of words to their meaning.
