用正电子发射断层扫描(PET)研究了7名以汉语为母语(L1)和后来学习英语(L2)的受试者的脑组织结构。当从L1和L2的动词生成中减去单词重复的激活时，两种语言的左下额下部、额叶背外侧、颞叶和顶叶皮质以及右侧小脑的CBF都观察到增加。直接比较动词生成和单词重复的差异在第一语言和第二语言中的差异。在L1和L2中，受试者内部减去单词重复导致所有个体的左侧额叶皮质CBF增加，而差异的比较没有发现额叶峰值的空间分离。我们主张共享神经基础，即使是像普通话和英语这样截然不同的语言。(C)1999年，Lippincott Williams&Wilkins。
POSITRON emission tomography (PET) was used to investigate cerebral organization in seven subjects who had Mandarin Chinese as their native language (L1), and learned English (L2) later in life. When activation from word repetition was subtracted from verb generation in L1 and L2, CBF increases were observed for both languages in left inferior frontal, dorsolateral frontal, temporal and parietal cortices, and right cerebellum. Direct comparison of the difference between verb generation and word repetition in L1 and L2 differences. Within-subject minus word repetition yielded CBF increases in left frontal cortex for all individuals for L1 and L2, and a comparison of differences yielded no spatial separation in frontal peaks. We argue for shared neural substrates even for such contrasting languages as Mandarin and English. (C) 1999 Lippincott Williams & Wilkins.
