Washington University scientists in St. Louis have devised a technique that, for the first time, shows what the brain does when the skull accelerates.

The researchers took a technique originally developed to measure cardiac deformation and used it to image deformation in human subjects during repeated mild head decelerations.

The scientists used magnetic resonance imaging to gathered data that show the brain — connected to the skull by numerous vessels, membranes and nerves at its base — tries to pull away from those attachments, leading to a significant deformation of the front of the brain.
