Allen Human Brain Atlas
This is the online help for the ALLEN Human Brain Atlas web application.
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.
- Microarray data 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 situ hybridization 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
- Autism Study of 25 genes in frontal, temporal and occipital cortical regions of 11 control and 11 autism cases
- Neurotransmitter Study characterizing expression of selected neurotransmitter system genes in major cortical and subcortical areas of adult human brain
- 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
