FMRI OF HUMAN BRAIN LANGUAGE SYSTEMS

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。该项目的主题是使用功能性磁共振成像来研究人类大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处理途径连接听觉spectrotemporal信号的语义和正字法输入的语义，这些处理流部分重叠，允许在语言水平的代表性的视觉整合。实验将涉及测量相对大脑激活的变化，在操纵听觉输入，字形和视觉对象的输入，选择性注意的要求，和任务指令。

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.
