This is the online help for the ALLEN Human Brain Atlas web application.
The Dataset
The Allen Human Brain Atlas is a unique multi-modal atlas of the human brain, integrating anatomic and genomic information and coupled with a suite of visualization and data mining tools.
Key features:
Microarraydata providing an "all genes, all structures" survey in multiple adult control brains
Genome-wide coverage - over 62,000 gene probes per expression profile
Comprehensive anatomic coverage - approximately 500 samples per hemisphere across cerebral, cerebellar and brainstem structures
Mapped with histology into unified 3-D anatomic framework based on MRI
Anatomic and gene-based search with options for comparing among structures or donors
Heat map and other viewing options, as well as files available for download
In situhybridization image data comprising multiple data sets from targeted studies covering selected genes in specific brain regions
Subcortex study examining 55 genes across subcortical regions and 10 additional genes in hypothalamus in one male and one female donor
Cortex Study surveying 1,000 genes in visual and temporal cortex in multiple adult control brains
Schizophrenia Study of 60 genes in dorsolateral prefrontal cortex of over 50 control and schizophrenia cases
MRI data for brains used for all microarray and some ISH analyses
Multi-planar viewer for structural MRI
T1, T2 and DTI files for download
Brain Explorer® 3-D viewer for interactive viewing of brain anatomy and gene expression distribution, including inflated cortical surface views
