It has been found that anxiety is helpful for individuals in a crisis.

French scientists have discovered that the brain tends to devote more resources to precarious situations than to pleasant ones. This may be a clue as to the sixth sense we possess and which is activated in rare circumstances.

Especially in times of danger, mankind tends to develop more dimensions to his being. This is the first time that particular portions of the brain that are involved in this process have been studied. All it takes is 200 milliseconds for the human brain to detect any animosity or “fear factor” in the air.

Furthermore, those with anxiety tend to have different portions of their brains light up than more hardy and relaxed people. Some believed that threat signals lead to more of a sensitivity being shown by the anxious.

However, the latest evidence suggests that the difference in neurocircuitry has a purpose. Those who are anxious process signals based upon a part of the brain responsible for action.

Meanwhile, those who are more laid back tend to process such signals via a region in the brain that is responsible for face recognition.

The display of threatening behavior through facial expressions can be confusing in many ways. What is taken as a threat may not be so and vice versa.

The direction in which a person is facing or staring is the crux of the matter. It determines many things. Dirty looks plus a strong way of staring go a long way in making the other person’s brain do a double-take.

Within the next 200 milliseconds, the other person responds with lightning quick alacrity. And this response is extinguished if the angry person looks elsewhere instead.

So in a crowd of people, if an angry person looks at you, you will respond with anxiety. But if he doesn’t, then you will definitely not be showing such a reaction.

In a similar manner, if a fearful person looks at you, the response will be likewise. If he shows positivity, then such a response will not be forthcoming. These seat of the pant reactions could have played a vital role in our survival tactics.

Since in our long struggle throughout prehistory, we lived side by side with other creatures which stung us, bit us and attacked us, such a gut instinct was very real.

It served an important function in our evolution. The electrical chemistry of the brain shows that its processing of such signals is very fine-tuned indeed.

The findings of this study has been published in eLife by title "Anxiety dissociates the adaptive functions of sensory and motor response enhancements to social threats".
