Anxiety and fear are extinguished in the brain discovered the mechanism that cancels

Anxiety is one of the problems in the modern age also affects the unexpected. Around the world millions of people suffer every day of anxiety, but could find neither a subsidiary nor a permanent solution. A sense of constant fear for anything, for any situation, create panic immobilizing any initiative.

It seems hell, but researchers are happy to announce that not only is not one of Dante's circle, but out is easier than you might think. A group of researchers at Stanford University in California, has discovered the brain mechanism that remove fear and anxiety on individuals, making public the study in Nature online.

Possible that a "switch" in the brain can lead us out of the state of anxiety? How many times have we thought that the woman without fear because of the lack of the amygdala was a lucky woman? Yet, though about one in four risk of a panic attack at least once in their life, the truth is that it is more widespread than we think.

Being prey anxiety puts us in a position to believe that the problem is only ours and no one else and no one can offer a solution. The American researchers, however, have discovered that by stimulating a brain circuit that is inside the structure that keeps the gray matter, it could counteract the anxiety.

For now, the tests on mice have shown that when the mechanism triggered by light pulses, increases the risk appetite of the mice, while inhibiting it makes them more timid and fearful. In this way, you can counteract the deleterious effects of anxiety in humans, possibly creating better drugs to help people with anxiety disorders because the human brain is structured in a manner similar to that of mice on which they were conducted tests.

By inhibiting this specific area of \u200b\u200bthe brain, the mice were more comfortable in situations that previously caused them anxiety and fear, being more uninhibited and casual. Doing a quick calculation, there would be more benefits than harm to live without anxiety. If video games cause anxiety and depression in adolescents, the situation has been going on then this young age up to the more adult, where the most disparate situations put the brain on alert.

This switch magic could solve several problems in one fell swoop, not least those of social and personal relationships. It would be a much better world without fears and anxieties that hinder us every day, whether or not we realize it. Unfortunately, who knows how long must we wait before being discovered, a remedy is also effective in humans.

Meanwhile, we try to implement behaviors as relaxed as possible, to avoid the panic that beset us even when its not expected.
