When soldiers are caught in an explosion, the blast releases intense vibrations. These pressure waves bombard — and damage — tissues throughout their bodies. Most of those tissues will heal with time. But effects on the brain can be severe and long lasting. That damage is called traumatic brain injury, or TBI for short. Scientists still aren’t exactly sure what goes on inside the brain to create TBI. But if they could figure it out, they might be able to help prevent it. One research team suspects those pressure waves create bubbles in the brain. And their new data show that if they do, such bubbles could cause the types of damage that could lead to TBI.
