FMRI OF HUMAN BRAIN LANGUAGE SYSTEMS

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。这个项目的主题是利用功能磁共振成像研究人脑中语言系统的功能和解剖组织。我们假设，颞叶内的特定区域参与了将听觉光谱时间信号与语义和正字法输入与语义联系起来的处理路径，并且这些处理流部分重叠，允许在语言表示水平上的听觉-视觉整合。这些实验将包括测量听觉输入、字形和视觉物体输入、选择性注意要求和任务指令操作过程中相对大脑激活的变化。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The theme of this project is to study the functional and anatomical organization of language systems in the human brain using functional magnetic resonance imaging. We hypothesize that specific regions within the temporal lobe are involved in processing pathways linking auditory spectrotemporal signals to semantics and orthographic input to semantics, and that these processing streams partially overlap, permitting auditory-visual integration at a linguistic level of representation. The experiments will involve measurement of relative brain activation changes during manipulation of auditory input, graphemic and visual object input, selective attentional demands, and task instructions.
