What a concussion looks like in the brain, on the cellular level

We need something like this for stroke. It may be in rats but we have to start somewhere. This could provide indisputable proof of the neuronal cascade of death. And that might get researchers to solve for that problem. But only if we have stroke leadership pushing that strategy.

Scientists have captured in real-time video what happens to a brain cell after experiencing a major concussion-causing impact.

The detailed video was created as part of a new study published in the journal Scientific Reports on Tuesday. It shows a rat's brain cell -- not those of a human -- but the research provides the first-ever glimpse of a concussion's effects on the cellular level at such high resolution and over a 24-hour timeline, said Christian Franck, an assistant professor at Brown University's School of Engineering and a co-author of the study.

He added that the study findings could hold clues about how to treat human brain trauma victims more quickly and effectively, as the video timeline reveals that irreversible damage begins about six hours after impact.
