This is remarkable, not just because it has been done, but also because they have made it free to researchers world-wide.
“The BigBrain atlas offers nearly cellular resolution, that is detail close to the level of the cell, a capability that has not been previously available in 3D for the human brain,” says Dr. Alan Evans, researcher at The Neuro, co-founder of the International Consortium for Brain Mapping and co-creator of the atlas. “To put BigBrain in context, we can consider present day MRIs which have a 3D spatial resolution of 1mm. In comparison, the BigBrain data set is 50 times smaller in each dimension providing unmatched spatial resolution. The BigBrain data set is 125,000 times (50 x50 x 50) bigger than a typical MRI, and has a volume of 1 terabyte, which is equal to 1000 GB.”
