Opportunity Information: Apply for RFA NS 22 047

The BRAIN Initiative Connectivity across Scales (BRAIN CONNECTS) Comprehensive Centers opportunity (RFA-NS-22-047) is a National Institutes of Health (NIH) funding announcement that supports large, coordinated research centers focused on building next-generation approaches for mapping brain circuit connectivity in humans and non-human primates. The central goal is to push technologies and workflows to a point where they can realistically scale into brain-wide connectivity atlases, while still preserving very fine detail. In practical terms, the centers funded under this FOA are expected to show that it is feasible to map region-to-region wiring with a minimum resolution at the level of individual cells and/or individual axon fibers, rather than stopping at coarse regional connections.

A key emphasis of the program is end-to-end capability, meaning these centers are not only expected to generate data, but also to establish robust pipelines for collecting, processing, analyzing, and sharing it. That includes standardized approaches for tissue handling and imaging (or other acquisition methods), computational methods for reconstruction and connectivity inference, quality control, metadata capture, and dissemination strategies that make the outputs broadly usable. The intent is for each center to operate like a comprehensive engine that can take a defined brain sub-volume from sample acquisition through to a shareable, analyzable connectivity product, demonstrating that the approach could be expanded to much larger portions of the brain over time.

Rather than producing maps as a purely descriptive exercise, the FOA also requires centers to demonstrate why the resulting wiring information matters scientifically. Each center is expected to choose a specific CNS sub-volume as a testbed and use the connectivity mapping approach to evaluate concrete hypotheses that connect circuit structure to function. This “hypothesis-driven demonstration” component is meant to show that the technology and pipeline are not just technically impressive, but also capable of producing insights that move neuroscience forward by linking anatomical circuitry to functional outcomes.

Another major requirement is interoperability and integration across scales and modalities. The FOA highlights that centers should incorporate toolsets and infrastructure that allow separately collected datasets to be integrated, including data acquired from smaller tissue volumes and data coming from different measurement modalities. This reflects a broader BRAIN CONNECTS strategy: no single method will cover every scale perfectly, so the program is pushing the field toward frameworks that can combine information across different resolutions (from micro-scale cellular detail to macro-scale region-level wiring) and across different types of experimental or imaging data. Just as importantly, centers are expected to make the resulting resources usable to the wider community by providing ways for neuroscientists to interact with the datasets, explore them, and mine them for new research questions beyond the original aims of the center.

Organizationally, awards made through this announcement are intended to function as part of a coordinated network rather than isolated projects. Funded centers become part of the BRAIN CONNECTS Network, alongside projects supported through this FOA and companion announcements. The network concept signals shared expectations around coordination, harmonization, and collective progress toward a long-term deliverable: wiring diagrams that can span entire brains across multiple scales. This cooperative, networked structure is reinforced by the funding mechanism itself: a cooperative agreement (UM1), which typically involves substantial programmatic coordination and involvement compared with standard investigator-initiated grants. The FOA is explicitly labeled “Clinical Trial Not Allowed,” indicating the supported work should not be structured as a clinical trial under NIH definitions.

In terms of who can apply, the eligibility is broad and includes many types of U.S. and non-U.S. organizations. Eligible applicants listed include state, county, city, township, and special district governments; independent school districts; public and state-controlled institutions of higher education; private institutions of higher education; federally recognized Native American tribal governments; tribal organizations that are not federally recognized; public housing authorities and Indian housing authorities; nonprofits with and without 501(c)(3) status (excluding higher education institutions in those nonprofit categories); for-profit organizations (other than small businesses); small businesses; and other entities. The FOA also explicitly calls out additional eligible applicant categories, including Alaska Native and Native Hawaiian Serving Institutions, AANAPISIs, Hispanic-serving institutions, Historically Black Colleges and Universities, Tribally Controlled Colleges and Universities, faith-based or community-based organizations, eligible federal agencies, regional organizations, non-domestic (non-U.S.) entities, Indian/Native American tribal governments other than federally recognized tribes, and U.S. territories or possessions. This breadth aligns with the scale and infrastructure-heavy nature of the work, which often benefits from multi-institutional collaborations and specialized capabilities.

From an administrative standpoint, the opportunity is classified as a discretionary grant program with NIH as the agency, and it falls under multiple CFDA listings (93.173, 93.213, 93.242, 93.273, 93.279, 93.286, 93.853, 93.865, 93.866, 93.867). The original closing date shown is June 13, 2023, and the FOA creation date is February 22, 2022. The award ceiling and expected number of awards are not specified in the provided source text, but the “Comprehensive Centers” framing and UM1 cooperative agreement mechanism generally indicate larger, multi-component efforts intended to serve as flagship contributors to the overall BRAIN CONNECTS mapping and data-sharing ecosystem.

Overall, this FOA is designed to accelerate the field toward practical, scalable, and community-accessible connectivity atlases for human and non-human primate brains. It does that by funding center-level efforts that can prove technical feasibility at high resolution, connect wiring maps to functional hypotheses in a defined CNS region, build integration frameworks for combining datasets across scales and modalities, and deliver tools and infrastructure that make the outputs usable well beyond the originating teams, all while operating as part of a coordinated national BRAIN CONNECTS network effort.
