“The human brain is just one big grid of neurons — a lot like the streets of Manhattan, minus Broadway, and then projected into three dimensions.”
A first map of the human brain reveals a simple, grid-like structure between neurons. This discovery by scientists from the National Institutes of Health (NIH) was made possible by new MRI scanner technology that is able to “peer through the folds of our wrinkly cerebral cortex” - and represents a major milestone in demystifying how we are wired.
“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.
