Allen Brain Atlas

Allen Brain Atlas is an Allen Institute collection of brain map atlases, datasets, APIs, and analysis tools covering mouse, human, and non-human primate brain resources.

Use Allen Brain Atlas when you need reference anatomy, gene expression, connectivity, cell type, or brain observatory resources with documentation and programmatic access paths. The strongest fit is atlas-guided neuroscience work where spatial context and reference structures matter.

Allen hosts many atlas and dataset families, so the correct documentation page depends on the specific resource being reused.

The Allen API DataSet model has subclasses and associations, so an API client should target the specific model needed for the atlas workflow.
