Always on my mind, the street grids of New York City

Tuesday, 3 April, 2012

The neuronal fibres that form the connections within our brains, rather than resembling a tangled collection of cables are set out in a far more grid like fashion, a little like the streets of downtown New York.

“Far from being just a tangle of wires, the brain’s connections turn out to be more like ribbon cables – folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric,” explained Van Wedeen, M.D., of Massachusetts General Hospital (MGH), A.A. Martinos Center for Biomedical Imaging and the Harvard Medical School. “This grid structure is continuous and consistent at all scales and across humans and other primate species.”
