Nikolaos Ziogas M.D., postdoctoral fellow at the Koliatsos Laboratory, was the winner of the “Post-Doctoral Fellow Poster Awards” at the annual National Capital Area Traumatic Brain Injury Symposium held at the National Institutes of Health, Bethesda, DC for the second consecutive year for his work “Diffuse axonal injury, blood brain barrier disruption and neuroinflammation after a single concussion with impact acceleration in the mouse”. A novel brain clearing technique, CLARITY, has been developed as a neuropathological tool for this work in order to visualize the whole mouse brain stem after concussion in single axon resolution, revealing widespread diffuse axonal injury.
