We are all familiar with the image of the human brain that consists of a muted gray rendering easily distinguished by a series of convoluted folds.
But according to Van Wedeen, a neuroscientist at Massachusetts General Hospital, in Boston, that image is just a shadow of the real brain.
By using Diffusion spectrum imaging (DSI) you can now see the brain as a collection of neural strings called axons. Scientists can use these diffusion measurements to map the strings creating a detailed blueprint of the brain's connectivity.
Why should we be surprise at this latest revolution that string theory is also applied to the greatest natural computer the human brain?
