Cerebral activation was compared during sign and spoken language comprehension. Nine hearing children of deaf parents were studied and the cerebral activation was measured by recordings of the regional cerebral blood flow. Comprehension of a complex material gave a bilateral activation of posterior temporal regions for both spoken and signed language. It seems that sign language activates the cortex in a way which is very similar to spoken language, when the listener watches the speaker. Cortical areas usually regarded to be important for spatial ability do not show enhanced activation during sign language perception.
在手势语和口语理解过程中对大脑激活情况进行了比较。研究了九名父母为聋人的听力正常儿童,并通过记录局部脑血流量来测量大脑激活情况。对于口语和手势语,对复杂材料的理解均使颞叶后部区域出现双侧激活。当听者观看说话者时,手势语似乎以与口语非常相似的方式激活皮层。通常认为对空间能力很重要的皮层区域在手势语感知过程中并未显示出增强的激活。
