通过功能磁共振成像（fMRI）研究了流利双语者对视觉呈现句子的理解，使用了两种拼写和语音不同的语言（普通话和英语）中的一组概念上相似的句子。在扫描过程中监测反应。将每种语言的句子理解与九个受试者的固定和五个受试者的泰米尔语伪字符串进行比较。在两种语言以及个人和团体分析水平的两个实验中，观察到前额叶、颞叶和上顶叶区域以及前辅助运动区的空间一致激活。早年接触两种语言的熟练双语者在书面语言的概念和句法处理过程中利用共同的神经解剖区域，无论表面特征如何差异。
Comprehension of visually presented sentences in fluent bilinguals was studied with functional magnetic resonance imaging (fMRI) using a set of conceptually similar sentences in two orthographically and phonologically distinct languages, Mandarin and English. Responses were monitored during scanning. Sentence comprehension in each language was compared to fixation in nine subjects and Tamil-like pseudo-word strings in five subjects. Spatially congruent activations in the prefrontal, temporal, and superior parietal regions and in the anterior supplementary motor area were observed for both languages and in both experiments at the individual and group levels of analysis. Proficient bilinguals exposed to both languages early in life utilize common neuroanatomical regions during the conceptual and syntactic processing of written language irrespective of their differences in surface features.
