In September 2011, the specialized Connectome Scanner was delivered to Massachusetts General Hospital. The hospital is a participating partner in the study. The Connectome Scanner uses diffusion MRI technology to map the flow of water along the neurons of the brain to reveal the internal map of how the neurons connect to each other.
In January 2012, the project released data from the first three human subjects.
In March 2012, the study announced that the structure of the brain is built on a three-dimensional grid-like structure. It is a surprisingly simple structure of fibers running parallel or perpendicular to each other creating curving boxes.
The studies continue and the Project is making data available.
