The inner ear is also probably responsible for motion sickness, which I get at the drop of a hat. I can get a sick feeling just thinking about being carsick. It's really awful. I'm told the inner ear in people who get motion sickness is extra sensitive or something to that effect. I don't know. I just know it's a terrible feeling to have.
I would like to see a definitive explanation on what exactly about the inner ear causes motion sickness. Dizziness is often a first symptom before the wracking nausea sets in.
