This is your brain experiencing a concussion

It may look like this model brain is made of Jell-O, but it’s the same consistency as a real brain.

As Dr. Christopher Giza from UCLA demonstrates, the brain is made of soft tissue and floats in fluid inside of the skull. When the skull moves quickly, the brain can jostle around a lot, which can lead to neurological symptoms.

“Most concussions are recoverable,” Giza said.

But concussions can be difficult to identify and some people suffer more serious symptoms, particularly after multiple concussions.

Lab studies have shown a “window of vulnerability” after a first concussion, Giza said. Concussed athletes are three to six times more likely to get another concussion. If they rush back to play, their reflexes, reaction time and thinking may be slower, putting them at risk of a second concussion and longer recovery period.
