Why do you get seasick on a boat and vomit

Why do you get seasick when on a boat and vomit. It is called a sensory mismatch.

When inside a cabin, your brain gets conflicting information. Eyes are telling everything is still, while inner ear senses motion.
Brain thinks it is being poisoned by neurotoxin and triggers vomiting to get rid of the toxin.

This hypothesis has been first suggested in a Science paper from 1977 by M. Treisman.
