SPARC Portal Roadmap

Suggest Edits

The overall vision and primary goals of the SPARC Portal - originally established to support the SPARC program - are to provide an open, sustainable online resource and infrastructure for peripheral neurosciences and bioelectronic medicine to the global scientific community and to foster collaboration. This scope represents a natural evolution from the first SPARC phase, when the SPARC Portal focused on the autonomic nervous system and on facilitating the exploration and use of the NIH SPARC Program’s scientific outputs, which include data, computational models, analysis pipelines, maps, standards, knowledge management, methodologies, and tools. The SPARC Portal, as well as established SPARC DRC infrastructure and curation services, will be offered and actively supported beyond the duration of the SPARC funding. They will continue to be maintained and enhanced with funding from institutional commitments, follow-up grants, and commercial offerings. The SPARC Portal and DRC will further broaden their mission to support open neurosciences and systems physiology “bridging the body and the brain” and ultimately drive the development of treatments that change lives.

Roadmap: Longer Term (beyond 2024)

  • Support for SPARC Phase 2
    • The Reconstructing Vagal Anatomy (REVA) initiative is creating more precise and detailed maps of the human vagus nerve, a bioelectronic highway that carries two-way electrical signals between the brain and internal organs of the body
      • continue development of the SPARC Portal and associated tools to host and work with these data products
    • The VNS Endpoints from Standardized Parameters (VESPA) initiative is identifying the physiological effects of altering vagus nerve activity to discover how best to stimulate nerve fibers for specific therapeutic effects

      • support the design, safety and performance assessment and optimization, and the development of control strategies
  • Compatibility with other research initiatives
    • Harmonization with research produced by other initiatives will be achieved with an increasing number of repositories and standards (the first already in 2024)
  • Search and supporting infrastructure
    • In the SPARC Portal, users will be able to combine searches based on maps (i.e., abstract or concrete representations of functional and anatomical relations) and graphs/ontologies (i.e., annotations that translate to unambiguous, standardized terminologies or represent relationships)
    • Given a particular entry on the SPARC Portal (e.g., dataset, image, etc.), users will have the ability to search the broader community by linking out to SciCrunch, PubMed, or other indexing servicess
  • Bridging the gap between experimental data collection and computational modeling
  • Ensuring reproducibility and FAIRness for data processing (e.g., shareable and explorable analyses, standardized machine learning)
