But I think Galaxy is right by saying "our lives are somehow over then". I mean if getting from point A to point B by car or by bus is no more possible, how to proceed with life? The fact that no one knowes what is going on inside the brain is the worst. I always tend to say, if you feel something, there is something wrong. Maybe in injured brains, those minor movements cause the axons to tear again? Who knows?

The question about CSF playing a role is indeed interesting.
