"It turns out your brain is organized even if you're not."

"At least that's the conclusion of a study in Science that looked at the network of fibers that carry signals from one part of the brain to another."

"Researchers used cutting-edge imaging technology to look at places where these fibers intersect. And they found a remarkably organized three-dimensional grid, says Van Wedeen of Harvard Medical School, the study's lead author."

"The grid is a bit like Manhattan, Wedeen says, 'with streets running in two dimensions and then the elevators in the buildings in the third dimension.'" 

"Of course the human brain has a lot of folds and curves. So, Wedeen says, you have to imagine Manhattan bent into some odd shapes. But the underlying grid doesn't change. The streets intersect at 90-degree angles and the buildings rise vertically."
