[Motion sickness exemplified by seasickness].

The knowledge of seasickness is as old as seafaring itself. In ancient times the Babylonians already reported on this malaise and on possible therapeutical measurements. The Babylonians, the advice of old sailors and modern pharmaceuticals have one thing in common. They have not been able to find a complete cure for motion disease. The interactions of the relevant cerebral structures are so complex that no drug is available which can interrupt this process definitively. The most important preventive measure is to develop strategies which lead to a quicker adaptation to movement.
