Using a new kind of MRI scanner, scientists at the National Institutes of Health mapped the connections in the human brain, revealing an intricate, grid-like structure.
"Before, we had just driving directions. Now, we have a map showing how all the highways and byways are interconnected," says Van Wedeen, a member of the Human Connectome Project. "Brain wiring is not like the wiring in your basement, where it just needs to connect the right endpoints. Rather, the grid is the language of the brain and wiring and re-wiring work by modifying it."
