A set of high resolution digital reference atlases have been created to provide neuroanatomical context to in situ hybridization, microarray, RNA-sequencing and axonal projection data.
From the API, you can:
The following Atlases are available through the API (click on Atlas ID to launch the interactive atlas viewer):

The sections for each Atlas come from a single AtlasDataSet (child class of SectionDataSet) and single Specimen. Typically, only a subset of AtlasImages (child class of SectionImage) is used for the reference atlas. An “annotated” image is identified by the SubImage “annotated” attribute and the corresponding image type. Please note that multiple line example RMA queries on this page use the “+” character to represent spaces for browser compatibility.
Examples:
http://api.brain-map.org/api/v2/data/query.xml?criteria=model::AtlasImage,
rma::criteria,
[annotated$eqtrue],
atlas_data_set(atlases[id$eq1]),
alternate_images[image_type$eq'Atlas+-+Adult+Mouse'],
rma::options[order$eq'sub_images.section_number'][num_rows$eqall]
http://api.brain-map.org/api/v2/data/query.xml?criteria=model::AtlasImage,
rma::criteria,
[annotated$eqtrue],
atlas_data_set(atlases[id$eq138322605]),
alternate_images[image_type$eq'Atlas+-+Developing+Human'],
rma::options[order$eq'sub_images.section_number'][num_rows$eqall]
Once the annotated images have been identified, the image ID can be used to download the colorized and labeled images using the Image Download Service and the vector graphics using the SVG Download Service.

In the API, a Structure represents a neuroanatomical region of interest. Structures are grouped into Ontologies and organized in a hierarchy or StructureGraph. With the exception of the “root” structure, each Structure has one parent and denotes a “part-of” relationship. Structures are assigned a color to visually emphasize their hierarchical position in the brain. See the Structure model page for listing of attributes and associations.
Major structural ontologies used in the Allen Brain Atlas Data Portal:
From the API, Structure and Ontology information can be downloaded in various formats.
