TV news station KSL recently highlighted research in Dr. Brittany Coats’ lab on the potential impact of arachnoid trabeculae in mild traumatic brain injury. Through optical coherence tomography imaging and finite element modeling, Dr. Coats’ group found that these microstructures dictate force distribution from the skull to the brain. By implementing the natural variability of the structures into their finite element models, they were able to improve predictions of extra-axial hemorrhage to 96% accuracy. Current efforts are being made to determine what leads to damage of these structures, and what effects damage could have on brain mechanics during secondary impacts.
