DTI FIBER TRACKING OF THE NIGRO-STRIATAL FIBER TRACT IN THE MONKEY BRAIN 7T

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 在非人类灵长类动物模型中开发高分辨率扩散张量成像（DTI）和扩散光谱成像（DSI）功能。本研究的目的是：1）通过与纤维束的组织学重建进行比较，验证DTI/DSI纤维跟踪算法。2)为了确定高分辨率弥散加权图像纤维追踪是否可以成像基底神经节回路内的小纤维束。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Development of high-resolution diffusion tensor imaging (DTI) and diffusion spectrum imaging (DSI) capabilities in the non-human primate model. The aim of this study will be to 1) validate DTI/DSI fiber tracking algorithms by comparing to histological reconstructions of the fiber tracts. 2) To determine whether high-resolution diffusion-weighted images fiber tracking can image small fiber tracts within the basal ganglia circuits.
