Collar Reduces Brain Sloshing to Help Prevent Concussions

Feb-07-16 A new collar that keeps the brain from “sloshing” around inside the skull could help prevent brain injuries caused by concussions.

Developed by a team from MIT, the collar was inspired by animals that are able to resist repeated blows to the head— such as woodpeckers and big horn sheep. According to the studies, the animals are able to adjust the pressure and volume of their skull to keep their brains stable. With that in mind, the team created a U-shaped collar device that fits against the back and sides of the person’s neck to apply gentle pressure to the jugular veins. This pressure slightly reduces the amount of blood that flows back into the heart after each beat, which helps decrease sloshing and lessen the chances of injury.
