为了研究传导性失语恢复过程中皮层的功能性重组，用二维133氙吸入法测定了10例脑卒中患者的局部脑血流量（rCBF）。在休息时和语言任务的执行过程中，发病后1个月和3个月进行rCBF测量。从休息到测试条件下的流量变化的分析表明，随着时间的推移，增加的贡献，右半球的Broca区的流量增加的情况下，这表明该地区是明确断开后语言“中心”的弓状束病变。
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.
