What is "bigbrain"

BigBrain is a freely accessible high-resolution 3D digital atlas of the human brain, released in June 2013 by a team of researchers at the Montreal Neurological Institute and the German Forschungszentrum Jülich and is part of the European Human Brain Project. The isotropic 3D spatial resolution of the BigBrain atlas is 20 µm, much finer than the typical 1 mm resolution of other existing 3D models of the human brain such as the Allen Brain Atlas. In 2014, BigBrain was cited in the top 10 MIT Technology Review.
