SPARC — bridging the body and the brain
The SPARC Portal is an open neuroscience and systems physiology platform containing multi-species data, knowledge, computational modeling and spatial mapping. Share your data and models to drive development of treatments that change lives.
Navigate the body's wiring diagram
Explore the body's neural pathways and anatomical connections, grounded in published science
Discover by topic
Browse datasets and models by experimental approach, anatomical structure, species, or contributing consortia
From Data to Discovery
Applications to visualize, simulate, and discover SPARC data, models, and knowledge
Query gene expression across cell types
Search any gene to see expression profiles across DRG neuron subtypes — UMAP projections and violin plots sourced directly from SPARC datasets.
Open NIH PRECISION Pain AtlasNavigate cell types interactively
Click any neuron bubble to surface its proposed relationships, marker genes, gene expression distribution, and axon phenotype.
Open NervoSensusBuild and run computational workflows
Connect services and models into reproducible pipelines. o²S²PARC lets you run simulations, share notebooks, and collaborate on computational studies — no local setup required.
Open o²S²PARCQuery SCKAN in plain English
Ask questions about neural connectivity in natural language. SCKAN NLI translates your query into structured SPARQL and returns grounded answers from the SCKAN knowledge base.
Open SCKAN NLIExplore SCKAN connectivity knowledge
Browse the full SCKAN connectivity graph — filter by species, organ, and pathway type to surface the anatomical evidence behind every nerve connection.
