【摘要】 目的利用BOLD-fMR I方法研究听觉性语言语音注意的神经机制。方法以B lock Design设计模式,刺激通过听觉呈现,对9名正常中国人分别进行词语语音注意的BOLD磁共振脑功能成像。结果所有受试者均完成了实验要求,且头动范围小于一个像素大小。语言任务激活的脑区包括:双侧颞中、上回,双侧额下回,双侧运动区及左侧角回。结论听觉语音注意作为一种调节功能在语言处理中发挥作用。更多还原

【Abstract】 Objective To stduy nuero-mechanismof Chinese auditory language in phonologic attention with BOLD-fM-RI.Methods 9 healthy volunteers were performed with blood oxygenation level dependent(BOLD) contrast functionalmagnetic resonance imaging(fMRI) on a1.5Tsystemwhen they were listeningactively to pseudowords of Chinese audito-ry language(word level).Results The activation areas of pseudowords of Chinese auditory language included bilateralsuperior temporal gyrus、bilateral inferior frontal gyrus、bilateral middle temporal gyrus、bilateral motor areas and left angu-lar gyrus.Conclusion Auditory phonologic attention plays a modulatory role for phonologic processing of auditory.更多还原
