鉴于有神经标记的非语言技能的收购，我们审查的证据神经标记的收购词汇。掌握词汇对于学习母语和学习其他语言都是至关重要的。习得需要将物体概念（意义）与声音联系起来的能力。是否存在对词汇知识敏感的区域？对于单语英语使用者来说，词汇知识的增加与顶叶皮层中灰质密度的增加相关，该区域位于调节意义和声音之间联系的位置（后缘上回）。此外，该区域还显示出对获得第二语言的敏感性。相对于单语英语者，意大利-英语双语者在同一区域显示出增加的灰质密度。词汇的神经标记可能存在差异，也可能存在共性，其中词汇的区别也是通过音调来表示的。相对于单语英语，中国多语言使用者，像欧洲多语言使用者，显示出增加的灰质密度在顶叶区域观察到以前。然而，无论种族如何，讲汉语的人（亚洲人和欧洲人）在两个右半球区域（上级颞回和额下回）也显示出非常显著的灰质密度增加。他们还显示左半球两个区域（颞中回和上级颞回）的灰质密度增加。这种增加可能反映了为了词汇目的而处理音调区别或为了区分词汇项目而存储音调差异所需的额外资源。最后，我们讨论了未来的调查路线。
Given that there are neural markers for the acquisition of a non-verbal skill, we review evidence of neural markers for the acquisition of vocabulary. Acquiring vocabulary is critical to learning one’s native language and to learning other languages. Acquisition requires the ability to link an object concept (meaning) to sound. Is there a region sensitive to vocabulary knowledge? For monolingual English speakers, increased vocabulary knowledge correlates with increased grey matter density in a region of the parietal cortex that is well-located to mediate an association between meaning and sound (the posterior supramarginal gyrus). Further this region also shows sensitivity to acquiring a second language. Relative to monolingual English speakers, Italian-English bilinguals show increased grey matter density in the same region. Differences as well as commonalities might exist in the neural markers for vocabulary where lexical distinctions are also signalled by tone. Relative to monolingual English, Chinese multilingual speakers, like European multilinguals, show increased grey matter density in the parietal region observed previously. However, irrespective of ethnicity, Chinese speakers (both Asian and European) also show highly significant increased grey matter density in two right hemisphere regions (the superior temporal gyrus and the inferior frontal gyrus). They also show increased grey matter density in two left hemisphere regions (middle temporal and superior temporal gyrus). Such increases may reflect additional resources required to process tonal distinctions for lexical purposes or to store tonal differences in order to distinguish lexical items. We conclude with a discussion of future lines of enquiry.
