OBJECTIVE:To test the capacity of a sentence verification (SV) task to reliably activate receptive language areas. Presurgical evaluation of language is useful in predicting postsurgical deficits in patients who are candidates for neurosurgery. Productive language tasks have been successfully elaborated, but more conflicting results have been found in receptive language mapping. MATERIALS AND METHODS:Twenty-two right-handed healthy controls made true-false semantic judgements of brief sentences presented auditorily. RESULTS:Group maps showed reliable functional activations in the frontal and temporoparietal language areas. At the individual level, the SV task showed activation located in receptive language areas in 100% of the participants with strong left-sided distributions (mean lateralisation index of 69.27). CONCLUSION:The SV task can be considered a useful tool in evaluating receptive language function in individual subjects. This study is a first step towards designing the fMRI task which may serve to presurgically map receptive language functions.

目的:测试句子验证(SV)任务的能力,以可靠地激活接受语言区域。语言的术前评估可用于预测神经外科候选患者的术后缺陷。生产性语言任务已成功完成,但在接受性语言映射中发现了更多矛盾的结果。
材料与方法:22名惯用右手的健康对照对听觉出现的简短句子进行了真假语义判断。
结果:群体图显示了额叶和颞顶语言区域中可靠的功能激活。在个人层面,SV任务显示激活位于100%的参与者的接受语言区域中,具有很强的左侧分布(平均横向指数为69.27)。
结论:SV任务可以被认为是评估单个对象的接受语言功能的有用工具。这项研究是设计fMRI任务的第一步,该任务可用于在术前映射接受性语言功能。
