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.

该子项目是利用 NIH/NCRR 资助的中心拨款提供的资源的众多研究子项目之一。子项目和研究者 (PI) 可能已从另一个 NIH 来源获得主要资金，因此可以在其他 CRISP 条目中得到体现。列出的机构是中心的机构，不一定是研究者的机构。该项目的主题是利用功能磁共振成像研究人脑语言系统的功能和解剖组织。我们假设颞叶内的特定区域涉及将听觉频谱时间信号与语义以及正字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，从而允许在语言表示层面上进行听觉-视觉整合。实验将涉及测量听觉输入、图形和视觉对象输入、选择性注意力需求和任务指令操作过程中相对大脑激活的变化。
