The human brain is the most complex piece of organized matter in the known universe. We’re working to uncover its mysteries.

Our brains are what make us human. They give rise to our thoughts, actions, movements and desires, store our memories, and enable us to navigate our world every day. Yet despite decades of research—and impressive knowledge gathered about other aspects of the human body, including our entire genetic sequence—the brain remains largely unknown. 

The Allen Institute for Brain Science was established to answer some of the most pressing questions in neuroscience, grounded in an understanding of the brain and inspired by our quest to uncover the essence of what makes us human.
