New imaging methods allow scientists to noninvasively observe the live brains of their human patients in two ways: as they perform tasks in functional imaging machines, enabling scientists to see which brain regions show simultaneous activation and thus imply connectivity, and in diffusion imaging scanners that model the pathways of the fiber bundles by recording water flow along the gradients of the cables.
