Some people can get motion sickness from being in moving vehicles such as cars or airplanes. But, a new device could stop motion sickness by suppressing some signals in the brain. Motion sickness occurs when the motion you sense with your inner ear is different from the motion you see. Symptoms of motion sickness are dizziness, nausea and vomiting. People have tried different ways to prevent the condition, including wrist bands and anti-nausea drugs. But often, nothing works. Now, scientists at Imperial College London are working on a device to counteract motion sickness. Michael Gresty is an expert on the condition. "You imagine being on a bicycle or motorbike; you go around the corner, you lean into the corner, which remains perfectly upright in physics. "You don't do that in a car. You don't do that on a ship. You're actually struggling to find out what is upright and what's the best way of dealing with it."
* motion sickness = (비행기, 차, 배 등 탈 것의) 멀리/ device = 장치[기기]/ suppress = 억제하다; 진압하다/ sense = 감지하다, 느끼다/ inner ear = 내이(內耳)/ symptom = 증상; 징후[조짐]/ dizziness = 현기증, 아찔함/ nausea = 메스꺼움, 욕지기/ vomiting = 구토, 토하기/ wrist bank = 손목대/ anti-nausea drug = 구토 방지약/ counteract = (무엇의 악영향에) 대응하다/ expert on ~ = ~의 전문가/ lean into ~ = ~로 (몸을) 숙이다[굽히다/젖히다]/ upright = (자세가) 똑바른, 꼿꼿한
The device sends a weak electrical current through electrodes placed on a person’s head. The electric current appears to cause the brain to suppress signals that affect the inner ear. Researcher Qadeer Arshad says the scientists found “that it took longer for the individual to develop motion sickness and that they also recovered faster." The next step is to test the device outside the laboratory. Michael Gresty says there are no reports of unwanted side effects from the small amounts of electricity released by the device. The researchers hope a device that plugs into a smart phone and attaches to the head will be available within 10 years.
