A group of scientists from Cardiff University, in collaboration with engineers from Siemens, have created the most detailed scan of the white matter in a human brain. White matter refers to the connecting material, or the 'wiring' that connects regions of our brain together. The study also shows which way the signals in our brain move, as well as the density of the white matter in different regions.
