perceptual balance and "sea legs"
I'm sure everyone has experienced this. After coming off a boat trip of several days, I feel like the soild ground under me is swaying as if I'm still on waves. This can last for days.
What I wish to understand is what in the brain is causing this perception of balance once it is no longer being stimulated? I assume the brain has sort of temporarily rewired itself to help the eyes and muscles compensate for a pitching deck, so I can see how you'd get used to it after a few days at sea, but what exactly causes the brain to falsely create that sensation on flat ground when there's no stimulus remaining, and why?
