That is capable of human body?
Would you like to have six fingers instead of five? In an exciting study, recently published in the journal Nature Communications, the researchers decided to study the ability of people with extra fingers. This condition is known as polydactyly. Polydactyly affects about two out of every 1,000 newborns. But because it is believed that the extra toes do not need and will not operate them usually removed. However, this is not always the case: some people with polydactyly decide to leave extra fingers. So the researchers looked at the mother and son, who live with six fingers of his left hand. As a result, scientists have made a series of discoveries about its function. According to the study the changes in the human body should not be neglected.
It looks like an x-ray hand with six fingers
A man with six fingers?
So, studying the sixth finger of mother and son, first, scientists have identified anatomical features: it turned out that the mother and son, a sixth finger had its own muscles, nerves and tendons. Its comparable strength and independence movement was on a par with the other fingers.
As a sixth finger can become functional? When your brain grows and develops, he builds a "map" of your body. You can not feel or move parts of his body that are not represented on this map. The discovery that the mother and son can move six fingers, prompting researchers to think about how their brain "sees" a sixth finger. Scientists have found that each of the six fingers of the subjects was presented to the individual sections of the motor cortex. Finally, with the help of an elaborate video game, the researchers showed that their six-pointed subjects can perform tasks with one hand. It is also surprising and the fact that we are with you, the usual five-fingered creatures need both hands to solve such problems. By combining all the data, the researchers concluded that the extra limbs of the developing brain.

Remember the Indian carpenter from the Guinness Book of Records? His hands and feet to 14 fingers. We can only guess how amazing his brain.
So look Indian carpenter hands. On his hands and feet to 14 fingers
Why mutations - is it good?
Although the present study is limited by the data of only two subjects, its consequences, however, is far-reaching. Clear demonstration of the fact that a sixth finger increases the functionality of the hand, a convincing argument in favor of the human brain's ability to control the machines more complex than the human body. Investigation polydactyl hands and the brain that controls them, is a test example of the advantages of this unusual study. Scientists have made great efforts to control and standardization for example, the effectiveness of a particular drug can be determined at practically identical laboratory mice.
Laboratory mice are still favorite experimental research laboratories around the world
But there are those few who pursues exotic and unique animals: seeking the warmth of vipers, cold-adapted octopus or, as in this case, people with extra fingers. It turns out that additional limbs dreams can not be so terrible, and the human body and our brain is capable of much. It turns out so.
