我们使用正电子发射断层扫描技术研究了成年人在听母语故事、七岁以后习得的第二种语言故事和第三种未知语言故事时的大脑活动。与先前在单语者中观察到的类似，有几个区域被母语激活，而不是第二语言。第二种语言和未知的语言都产生了明显的左半球激活专门用于语音处理的区域，而这些区域不受向后语音控制任务的影响。这些结果表明，一些大脑区域是通过早期接触母亲的语言而形成的，并且不一定是通过处理他们在生命后期有限时间内接触的第二语言而激活的。
WE used positron emission tomography to study brain activity in adults while they were listening to stories in their native language, in a second language acquired after the age of seven, and in a third unknown language. Several areas, similar to those previously observed in monolinguals, were activated by the native but not by the second language. Both the second and the unknown language yielded distinct left-hemispheric activations in areas specialized for phonological processing, which were not engaged by a backward speech control task. These results indicate that some brain areas are shaped by early exposure to the maternal language, and are not necessarily activated by the processing of a second language to which they have been exposed for a limited time later in life.
