Among our most widely cited resources, these neuroanatomical atlases provide data-driven, high-resolution maps of the mammalian brain.
By examining brain cell types and connections across species at a refined level and at the most comprehensive scale – we are working towards understanding the structure and function of the human brain itself.

We share what we do openly with the world
We believe shared understanding accelerates new discoveries and nurtures breakthroughs. The Allen Institute openly shares datasets, software, protocols, lesson plans, modeling tools, machine learning algorithms, cell lines, plasmids – and more – to accelerate bioscience research and discovery worldwide.
Defining and characterizing the underlying gene expression, gene regulatory, and morphoelectric features of cell types in the human and non-human primate (NHP) brain.
Generating a complete multimodal cell census and atlas of the mouse brain through collaborative data collection, tool development and analysis.

Allen Institute cell types in CZ Cell x Gene
Based on ~1.4 million cells in middle temporal gyrus, the Seattle Alzheimer’s Disease Brain Cell Atlas (SEA-AD) atlas includes 139 transcriptomically distinct supertypes well conserved across aged donors and neocortical areas.
The ABC Atlas highlights the spatial localization of each cell type in donors with and without AD by visualizing these data alongside a complementary MERFISH data set profiling ~300 thousand cells.
CZ Cell x Gene further highlights genes associated with different cell types and disease states, allowing both scientists and students to ask specific questions about the molecular underpinnings of age and Alzheimer’s disease.
