Functional magnetic resonance imaging (fMRI) was used to compare the cerebral organization during sentence processing in English and in American sign language (ASL). Classical language areas within the left hemisphere were recruited by both English in native speakers and ASL in native signers. This suggests a bias of the left hemisphere to process natural languages independently of the modality through which language is perceived. Furthermore, in contrast to English, ASL strongly recruited right hemisphere structures. This was true irrespective of whether the native signers were deaf or hearing. Thus, the specific processing requirements of the language also in part determine the organization of the language systems of the brain.
功能磁共振成像(fMRI)被用于比较英语和美国手语(ASL)句子处理过程中的大脑组织情况。以英语为母语者处理英语以及以手语为母语者处理美国手语时,左半球内的经典语言区域都会被激活。这表明左半球倾向于独立于语言感知方式来处理自然语言。此外,与英语不同,美国手语强烈激活了右半球结构。无论以手语为母语者是聋人还是听力正常者,都是如此。因此,语言的特定处理需求也在一定程度上决定了大脑语言系统的组织方式。
