Your brain during a concussion.

1. NO helmet can protect that from happening

2. Right... Helmets protect the skull... not the brain. n/t

7. No, what they do is distribute the blow

and absorb a lot of the shock. Helmets are the difference between recovering and not recovering. They work.

The best idea is not to run into anything. If you do, you'd better be wearing a helmet unless you like the idea of being a veg kept alive by machines.

3. That is awesome! But (and this is serious) when I handled brains in school, they

seemed to be somewhat more rigid than that. Would that have been from the preserving agents?

4. My thoughts also. Seemed awfully pliable.

5. Like those Jello snacks we used to make!

6. Exactly!

8. For the purpose of the demo...

I think the point was to show the amount of movement that would occur with a blow hard enough to cause a concussion. He didn't seem to be using enough force for a real concussion. Just a guess.

9. Yeah, more like cream cheese than Jello

so a lot less wibbly than the demonstration. However, the bouncing around inside the skull does occur and that's not great for axons and dendrites and why after a concussion, any activity that risks another should be avoided for six months or so, give the brain a chance to reestablish those connections.
