EnglishWhat Is brain-map.org? The Allen Institute for Brain Science's Open Science Platform
Updated
brain-map.org is the public web platform of the Allen Institute for Brain Science, a research organization that characterizes and maps brain cells "with unprecedented precision and scale." The site is a gateway to large-scale, publicly available datasets, reference atlases, and computational tools rather than a commercial product or service. It is most useful to researchers, students, and anyone who needs authoritative anatomical or cell-type data on the mammalian brain.
What the site actually provides
The platform is organized around a few resource families, each tied to a research area:
- Brain Knowledge Platform — described as a "knowledge centered scientific workbench," the entry point for working with the institute's data.
- Atlases — large-scale, publicly available anatomical reference datasets and products.
- Research areas — the scientific disciplines the institute studies, each with related publications and data.
- Tools — computational analysis tools, genetic tools, and hardware designs created by institute scientists.
The atlases, in detail
The neuroanatomical atlases are described as among the institute's most widely cited resources, offering data-driven, high-resolution maps of the mammalian brain. The site lists these:
| Atlas | What it covers |
|---|---|
| Adult Mouse | Adult mouse brain in coronal and sagittal planes of section |
| Adult Human | Adult human brain, using modified Brodmann or gyral annotation |
| Developing Mouse | Developing mouse brain across seven embryonic and postnatal stages |
| Developing Human | Developing human brain across two embryonic stages |
| Mouse Spinal Cord | Mouse spinal cord in adult and juvenile C57BL/6J mice |
Each is a reference atlas: a standard anatomical space you can register other data against, not a single experiment.
Research focus areas
Beyond anatomy, the institute groups its work into disciplines, each with datasets and key publications:
- Cell Types & Taxonomies — data-driven classifications of cell types in the mammalian brain.
- Circuits & Behavior — data from the Allen Brain Observatory on neuronal circuitry.
- Connectivity — multiscale datasets on how the brain is wired.
- Computational Modeling & Theory — brain-wide, circuit-level, and cell-level biophysical models and tools.
- Gene Expression — gene expression data viewed through Allen Brain Atlas datasets.
- Genetic Tools — biological and technical resources for research.
- Computational Tools — analysis tools built by institute scientists.
- Hardware — custom instrument designs for a range of scientific use cases.
Who it's for, and how to start
The site suits anyone who needs standardized brain reference data: neuroscientists registering their own images, computational researchers looking for datasets to model, or students learning neuroanatomy. A practical starting path:
- Decide whether you need an atlas (a reference space) or a dataset (observations such as gene expression or connectivity).
- Open the relevant atlas or research area page and review the species, developmental stage, and annotation scheme before downloading.
- For analysis, check the Computational Tools section rather than building pipelines from scratch.
One caveat: the site describes its resources as publicly available datasets and products, but the provided material does not state pricing, licensing terms, or whether an account is required for any specific download. Confirm those details on the individual resource page before relying on a dataset in published work.
