Nebraska Researchers Working on 10-Minute Concussion Test

Uuu 513 Ab Headshot

Researchers at the University of Nebraska are developing a tool that could rule out or confirm a concussion within 10 minutes. The device, a functional MRI (magnetic resonance imaging) machine, would use an electrode net placed on an athlete's head to monitor brain activity in response to various stimuli. Based on subtle changes in blood flow, team medical professionals will be able to determine within minutes whether an athlete is concussed, and if so, how severely.

"We can get an idea of what area of the brain is being involved in the process, whether the speed of processing is at the rate it should be," said Dennis Molfese, director of the university's Center for Brain Biology and Behavior, which opens this month at Memorial Stadium. "The different areas of the brain that normally integrate information quickly stop doing that, so that's another way we should be able to pick up whether there is an injury or not."
