Quizplus · Accepted Answer

Motion sickness occurs when the brain is bombarded with conflicting sensory input.For example,suppose you are trying to read a book while riding on a bus.As the vehicle goes up and down hills and around curves,starts and stops,and hits the occasional pothole,the mechanoreceptors of your inner ear send information about all these changes in position to your brain.So do the proprioceptors in your joints and muscles and the mechanoreceptors in your skin.However,since your eyes are fixed on the pages of your book,the visual information that your brain receives says your position has not changed.The brain becomes overwhelmed,and motion sickness ensues.
