Could a Jolt to the Brain Stop Motion Sickness?
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."
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.

1.motion sickness 晕车；晕动病
For motion sickness, I took motion sickness pills.
2.such as 例如；比如
Heroes such as Huang Jiguang will always live in the hearts of the people.
像黄继光这样的英雄人物， 将永远活在人民的心里 。
3.inner ear 内耳
Time is therefore always ticking in their inner ear.

I am honored to be associated with brave little Dustin by wearing this silver and leather wrist band.

work on 致力于；从事于
From now on you can work on your own.
You can work on more than one goal at once but only have one goal per area, to balance them out.

I'll find out the address,and ring you back.
I shall make it my business to find out who is responsible.
晕车是因为内耳感受到的移动速率与眼睛所看到产生差距所致 。晕车的症状包括头晕、恶心、呕吐等 。人们已经在晕车这一问题上已尝试过多种办法，包括防晕车腕带以及一些抗恶心药物 。
但如果你在车上或是船上的时候就另当别论了 。其实关键就在于明白什么才算是直立以及如何保持直立的姿态 。”
该设备通过在人体头部安放电极发送弱电流来达到防晕车的目的 。电流能够让大脑发出影响内耳的信号 。
