Whole Mouse Brain Atlas Publication Package Highlights (Feb 1, 2024)

The millions to billions of cells that comprise mammalian brains are organized into many highly specialized cell types. Previous studies have demonstrated that known and novel cell types can be identified by their single-cell gene expression profiles. However, the actual number of cell types in the brain and the degree of diversity among these cell types has been unknown. This webinar presents a new collection of studies from the BRAIN Initiative Cell Atlas Network (biccn.org) and published in Nature on Dec 14, 2023, that report the first complete cell type atlas of a mammalian brain, with over 30 million cells profiled from the adult mouse brain using a combination of single-cell transcriptomic, epigenomic, and spatial transcriptomic approaches, identifying over 5,300 cell types in the entire mouse brain. These studies uncover multitudes of organizing principles of the extraordinary cell type diversity across the brain. This collective body of work represents a landmark achievement that will have far-reaching impact on understanding cell type-based brain circuit function across the neuroscience field.

Human and Non-Human Primate Cell Atlas: Publication Package Highlights (Oct 26, 2023)

The human brain contains more than 100 billion cells, but exactly how these cells are organized into types and how these cell types differ between brain regions and species is an open question. This webinar presents a new collection of studies focused on defining and characterizing the underlying gene expression, gene regulatory, and morphoelectric features of cell types in the human and non-human primate (NHP) brain. These studies employ a range of cellular resolution methods (most notably single cell genomics) for this purpose, marking the beginning of an exciting new era of high-resolution human and NHP analyses. The implications for understanding of human brain function, disease and disease modeling are profound.
