Seasick? Your brain thinks it was poisoned – Observer

The sickness when riding a car (or any other means of transport) are a nightmare for many people. Although already know some solutions, the cause was not yet clear. Many say it is due to a disorder of the inner ear, which creates a sense of imbalance. But neuroscientist Dean Burnett has another answer in his book Idiot Brain:. What your head is really up to account The Telegraph

researcher at Cardiff University believe that the feeling of nausea arises because the brain believes he was poisoned and, as such, sends the message that you need to throw up the toxin. This is because the brain takes opposite signs and can not assimilate, since the body is stopped, but the landscape to pass indicates motion. In addition to visual stimuli, so the balance sensors ears indicate movement, although the body is at rest.

The doctor explained his theory saying that “in evolutionary terms, the only thing that can cause a sensory mismatch is a neurotoxin, or poison. So the brain thinks, essentially being poisoned. When you are being poisoned, the first thing you do is get rid of the poison, or throw up. “So, nausea and want to vomit arise because the brain triggers a protective mechanism as it does not realize well what is going, then decides to get rid of the potential threat.

Read or look at screens worsens this feeling because, looking at the window, the brain perceives better than is actually moving, although the body do not move and feeling sick decreases because the brain interprets better what is happening. According to neuroscientist, other examples showing that the brain is not yet adapted to the demands of the modern world are the jet-lag or anxiety.
