Which research institute founded by Paul Allen focuses on mapping the brain?

The Allen Institute for Brain Science is the research institute founded by Paul Allen to advance brain mapping and neuroscience. Allen provided $100 million in seed funding when the Seattle-based institute was established in 2003.

Its flagship work has included the Allen Brain Atlas, which catalogued gene-expression patterns in the mouse brain and made extensive data freely available to researchers. The institute later expanded into human brain data, developmental neuroscience, neural connectivity, and cell-type classification.

The phrase “mapping the brain” can refer to several different kinds of maps. Some projects show where genes are active, while others chart anatomy, neural connections, or the activity of individual cells. The Allen Institute for Brain Science is distinct from the Allen Institute for AI, another organization associated with Paul Allen, but focused on artificial intelligence rather than neuroscience.
