项目摘要

PROJECT SUMMARY A structural connectome can provide critical information for animal brain studies to study white matter bundles and correlate brain circuits with experimental findings. As more animal models for neurological disorders are widely used to understand the disease mechanism and test possible treatments, tractography atlases will help those studies to correlate white matter pathways with brain function or dysfunction. Here, we aim to construct tractography atlases at unprecedented details as structural connectome for mouse, rat, and rhesus macaque and developed associated toolboxes for novel tractography analytics. To achieve this goal, we have formed a multidisciplinary team between Duke Center for In Vivo Microscopy and the "DSI Studio" team at the University of Pittsburgh. At Duke CIVM, we will acquire the ultra-high resolution "beyond-tensor" diffusion MRI on the mouse, rat, and rhesus macaque brains to resolve complicated axonal structures. The image acquisition will be accelerated using compressed sensing and further reconstructed using a super-resolution approach. Besides MRI, the rat and mouse brain tissue will be processed by tissue clearing and scanned by light-sheet fluorescence microscopy to capture cell-level histology details of the entire brain. The diffusion MRI data will then be processed at the University of Pittsburgh to construct tractography atlases and develop novel automated tractography, shape analysis, and bundle analytics toolboxes. We will track whole-brain pathways and cluster them into bundles. Our neuroanatomist team will validate tractography against publicly available tracer data and aggregate the results in tractography atlases, which will be used to build their associated atlas- based automated tractography and associated analysis. The completion of this study will provide a mesoscale structural connectome with integrated histologic images at unprecedented quality as well as their associated toolboxes. The data and tools combined will serve as invaluable resources for animal studies to investigate brain disorders.
项目摘要 结构连接体可以为动物脑研究白色物质束提供关键信息 并将大脑回路与实验结果联系起来。随着越来越多的神经系统疾病的动物模型 纤维束成像图谱被广泛用于了解疾病机制和测试可能的治疗方法, 这些研究将白色物质通路与大脑功能或功能障碍联系起来。在这里,我们的目标是构建 纤维束成像图谱在前所未有的细节,如结构连接体的小鼠,大鼠和恒河猴 并开发了用于新型纤维束成像分析的相关工具箱。为了实现这一目标,我们成立了 杜克中心体内显微镜和“DSI工作室”团队之间的多学科团队在大学 匹兹堡。在杜克CIVM,我们将在 小鼠、大鼠和恒河猴大脑,以解析复杂的轴突结构。图像采集将 使用压缩感测加速,并使用超分辨率方法进一步重构。除了 MRI中,大鼠和小鼠脑组织将通过组织清除处理并通过光片扫描 荧光显微镜以捕获整个大脑的细胞水平组织学细节。弥散MRI数据将 然后在匹兹堡大学进行处理,以构建纤维束成像图谱,并开发新的 自动化纤维束成像、形状分析和束分析工具箱。我们将追踪整个大脑的通路 并将它们聚集成束。我们的神经解剖学家团队将验证纤维束描记术, 跟踪数据,并将结果汇总到纤维束成像图谱中,该图谱将用于构建其相关图谱- 基于自动纤维束成像和相关分析。这项研究的完成将提供一个中尺度的 结构连接体与整合的组织学图像在前所未有的质量,以及他们的相关 工具箱这些数据和工具将成为动物研究的宝贵资源 大脑紊乱
