First map of the human brain reveals a simple, grid-like structure between neurons
In an astonishing new study, scientists at the National Institutes of Health (NIH), have imaged human and monkey brains and found… well, the image above says it all. It turns out that the pathways in your brain — the connections between neurons — are almost perfectly grid-like.
It’s rather weird: If you’ve ever seen a computer ribbon cable — a flat, 2D ribbon of wires stuck together, such as an IDE hard drive cable — the brain is basically just a huge collection of these ribbons, traveling parallel or perpendicular to each other. There are almost zero diagonals, nor single neurons that stray from the neuronal highways. 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.
