In September 2003, Allen launched the Allen Institute for Brain Science with a $100 million contribution dedicated to understanding how the human brain works. In total, Allen donated $500 million to the institute, making it his single largest philanthropic recipient. Since its launch, the Allen Institute for Brain Science has taken a Big Science and open science approach to tackle projects. The institute makes research tools available to the scientific community using an open data model. Some of the institute's projects include the Allen Mouse Brain Atlas, Allen Human Brain Atlas and the Allen Mouse Brain Connectivity Atlas. The Allen Institute is also helping to advance and shape the White House's BRAIN Initiative as well as the Human Brain Project.
