我们使用功能磁共振成像(FMRI)来研究在健康受试者的大脑中，在处理被动句子与主动句子的过程中，布罗卡区的激活是否更大。20名以日语为母语的人进行了一项视觉句子理解任务，要求他们阅读一个视觉呈现的句子，并通过按下按钮来识别句子中的代理人或患者。我们发现，在Broca‘s区，被动句的激活程度并不比主动句强。然而，在左额盖和顶下小叶，被动句比主动句引起更大的激活。因此，我们的神经成像结果表明，日语失语症患者对被动句的理解障碍不是由Broca区的损害引起的，而是由左额盖和/或顶下小叶引起的。(C)2006爱思唯尔有限公司。保留所有权利。
We used functional magnetic resonance imaging (fMRI) to investigate whether activation in Broca's area is greater during the processing of passive versus active sentences in the brains of healthy subjects. Twenty Japanese native speakers performed a visual sentence comprehension task in which they were asked to read a visually presented sentence and to identify the agent or the patient in the sentence by pressing a button. We found that the processing of passive sentences elicited no greater activation than that of active sentences in Broca's area. However, passive sentences elicited greater activation than active sentences in the left frontal operculum and the inferior parietal lobule. Thus, our neuroimaging results suggest that deficits in the comprehension of passive sentences in Japanese aphasics are induced not by lesions to Broca's area, but to the left frontal operculum and/or the inferior parietal lobule.
