Emily and Amy speak to Doris Bamiou (UCL Ear Institute, UK) about the vestibular system and how it provides our brain with information about where our body is in space, and Raymond Reynolds (University of Birmingham, UK) about what can happen when things go wrong with our vestibular system. They also discuss: Dizziness in discus and hammer throwers, why some people feel nauseous when watching 3D films, and do blind people have better hearing than sighted people?
