In order to investigate functional cortical reorganization during recovery from conduction aphasia, regional cerebral blood flows (rCBF) were measured by the two-dimensional 133 Xenon inhalation method in ten stroke patients. rCBF measurements were performed at rest and during the performance of a linguistic task, one month and three months after onset. The analysis of flow changes from rest to test condition indicates an increasing contribution of the right hemisphere as time goes on. The absence of flow increase in Broca's region suggests that this region is definitively disconnected from posterior language "centers" by the arcuate fasciculus lesion.
为了研究传导性失语恢复过程中的功能性皮质重组,采用二维氙-133吸入法对10例中风患者的局部脑血流量(rCBF)进行了测量。在发病后1个月和3个月,于静息状态和执行语言任务期间进行rCBF测量。对从静息状态到测试状态的血流变化分析表明,随着时间的推移,右半球的作用越来越大。布洛卡区血流未增加,提示该区域因弓状束病变而与后部语言“中枢”完全断开联系。
