Science with Simon Pollard

In the skull behind the eardrum is the inner ear which contain remarkable fluid-filled sense organs. These organs send messages to the brain which help to give us a sense of orientation and allow our body to react to movement. But sometimes these sense organs send the wrong or conflicting messages. Simon discusses how vertigo and motion sickness can be the result. And why does a room appear to spin, when you lie down after drinking too much alcohol?
