Allen Brain Atlas API

The Allen Institute for Brain Science offers access to its published data through an application programming interface (API). The API, documentation, sample applications, and 2012 Allen Brain Atlas Hackathon materials are made available to the community under the Allen Institute's Terms of Use in hopes of facilitating discovery.

Available Data and Services
  • High resolution images
  • Primary microarray results
  • Exon microarray summarized to exons and genes
  • Samples mapped to MNI space
  • Grid-level gene expression values registered to a reference atlas space
  • Reference atlas ontologies and 3-D models
  • Image-to-Image Synchronization Service
  • Differential Expression Service
  • NeuroBlast Search Service

Examples of studies with data and services made available through the Allen Brain Atlas API include:
