A collection of interactive tools and prototype applications for the Seattle Alzheimer’s Disease Brain Cell Atlas (SEA-AD). These applications provide access to gene expression, cell type, trajectory, neuropathology, and annotation exploration resources.

MTG Trajectory Viewer

MTG Trajectory Viewer

Identify and visualize cell type-specific gene expression changes across AD pseudo-progression in MTG.

SEA-AD Multiregion Viewer Icon

SEA-AD Multiregion Viewer

Explore gene expression patterns in multi-region single cell data in the context of cell types, brain regions, and disease progression.

Neuropathology Viewer

Neuropathology Viewer

Explore neuropathology images and associated measurements from multiple brain region in SEA-AD donors.

Annotation Comparison Explorer (ACE)

Annotation Comparison Explorer (ACE)

Compare cell type annotations between SEA-AD and ten community studies of AD or user data from MapMyCells.

Cell Hierarchy Gene Explorer (CHARGE)

Cell Hierarchy Gene Explorer (CHARGE)

Identify genes of potential biological interest in multiple cell type taxonomies (including SEA-AD MTG).

Gene Knowledge Cards

Gene Knowledge Cards

Explore patterns of gene expression in the brain across multiple Allen Brain Atlases (including SEA-AD).

Allen Brain Map Resource Finder

Allen Brain Map Resource Finder

Visit a user-friendly entry point into tools and resources available on Allen Brain Map and SEA-AD.org.
