The Allen Human Brain Atlas contains multimodal data integrated into a unified 3-D framework with search and visualization features allowing one to journey through the brain readily climbing up and down levels of resolution.

<p>See it in action: Check out video tutorials on the Allen Human Brain Atlas and Brain Explorer® 3-D Viewer. Key Features: An “all genes, all structures” gene expression survey in multiple adult control brains. • >62,000 gene probes per profile. • ∼500 samples per hemisphere across cerebrum, cerebellum, and brainstem. • Data mapped with histology into unified 3-D anatomic framework based on MRI. High-resolution ISH image data covering selected genes in specific brain regions. • Subcortex Study: 55 genes across subcortical regions and 10 additional genes in hypothalamus in one male and one female donor. • Cortex Study: 1,000 genes in visual and temporal cortices in multiple adult control brains. • Schizophrenia Study: 60 genes in dorsolateral prefrontal cortex of over 50 control and schizophrenia cases. • Autism Study: 25 genes in frontal, temporal and occipital cortical regions of 11 control and 11 autism cases. • Neurotransmitter Study: Selected neurotransmitter system genes in major cortical and subcortical areas in adult control brains. MRI data for brains used for all microarray and some ISH analyses. Search and viewing tools, including: • Brain Explorer® 3-D viewer. • Heatmap viewer for exploring microarray data across genes and brain regions. • Gene-based and anatomic search features. • Multiplanar MRI viewer with gene expression overlay. • Linked viewing of MRI, gene expression, histology, anatomic delineations.</p
