Traumatic brain injury patients, supercomputer simulations studied to improve helmets

energy from the blasts. The hyperactive regions are those that experienced the least shear and tensile energies, according to the computer simulations, which can be used to predict where the hyperactivity will likely occur, they say.

The studies also showed problems with how the patients used visual information, which corresponded to their complaints about having difficulty with attention spans, Ford said.

"This is our way to validate what the simulation shows with the clinical reality," he said.

Once Taylor and Ford determine exactly how and where the wave energy deposited in the brain gives rise to injuries, they can provide thresholds of stress and energy levels that cause TBI for consideration by helmet designers, Taylor said.

"I want us to be able to understand the physical mechanisms that lead to TBI. It would also be useful if we could make the connection between blast loading and blunt impact trauma," Taylor said. "Once we understand that we can be more comprehensive in how we protect both our warfighters and athletes against these sorts of injuries."
