Traveling makes us feel sick because modern transport tricks the brain into thinking we have been poisoned, a neuroscientist has said. 一位神经系统科学家表示，现代交通工具会诱导大脑认为我们已经中毒，所以旅行常常使我们感到不舒服。 Being in a car, train, boat or plane causes conflicting signals in the brain which trigger a reaction similar to that which occurs when someone is poisoned. 乘坐汽车、火车、船舶或飞机的体验会在大脑中形成相互矛盾的信号，这会引发和人们中毒时相似的反应。 Dr Dean Burnett, of Cardiff University, said the feeling of nausea is caused because the brain thinks the body needs to remove a toxin through vomiting. 卡迪夫大学的迪安•伯内特博士称，大脑认为人体需要通过呕吐排毒，于是便造成了这种恶心感。 But in fact, the 'poisoning' effect is caused by the mixed messages from the muscles – which tell the brain the body is motionless – and the ears, which sense movement. 但事实上，这种“中毒”效应是由肌肉中的混合信息所引发的，肌肉向大脑传达身体静止的信息，而耳朵却察觉到身体在运动。 Speaking on the US radio show Fresh Air, Dr Burnett said that the body had not yet evolved to cope with the sensation of being in vehicles, where the body is being moved without performing movements itself. |
