PROJECT SUMMARY/ABSTRACT This project aims to disseminate validated technologies and resources of the National Center for Microscopy and Imaging Research (NCMIR) at UC San Diego to advance the completion of strategic goals of the BRAIN Initiative. The proposed technology integration and dissemination resource will provide the neuroscience community with technical help to obtain and manage large scale data, broadening the access to and incorporation of high throughput multiscale imaging tools and leading-edge analysis strategies in their studies. Richly integrated resources will be offered, including molecular probes, imaging platforms and data analysis tools certain to enable and hasten brain research. The types of research projects we will support, include: 1) investigations requiring the traversal of spatiotemporal scales to reveal new insight and understanding of specific neural populations; 2) investigations which aim to mark and track neuronal processes and/or visualize targeted connectomes of local circuits within large volumes of nervous tissue in multiple animal models; 3) projects which seek to perform nano-histological assessment of cellular and subcellular level alterations associated with learning, physiological state, or disease; and 4) projects performing higher resolution 3D morphometric analysis of subcellular underpinnings of function, with particular emphasis on synaptic function as influenced by subcellular constituents. This new center will leverage an administrative framework and information technology cyberinfrastructure which is already in place and has been refined over many years. In addition to providing a management structure, this framework includes a community outreach, project review, selection, and onboarding process refined and long practiced by the PI (and the assembled team). Additional mechanisms for tool/technology dissemination and training, data management and sharing, and mechanisms for cost-recovery and long-term sustainability will also be leveraged and expanded so as to maximize the reach and impact of our technologies and resources.

PROJECT NARRATIVE This project aims to disseminate validated technologies and resources of the National Center for Microscopy and Imaging Research (NCMIR) at UC San Diego to hasten the completion of strategic goals of the BRAIN Initiative for unlocking the role of different cell types and producing maps of brain circuits and ultrastructure at multiple scales. NCMIR will provide specialized molecular probes, novel specimen preparation methods, leading- edge microscopy and imaging technologies, and scalable computational tools to help brain investigators traverse difficult to navigate spatial and temporal scales, deliver new insight into multiscale structure/function relationships, and provide a fundamental understanding of the macromolecular mechanisms underlying brain function.
