And at the very end of XX century. it was shown that after brain damage nerve cells begin to proliferate in the two areas of the brain and migrate into the injury site. So again there are hundreds of thousands of nerve cells. Again, in fairness, and perhaps unfortunately optimists note that the human brain is small, but unknown to science in its cells as much as the objects in the universe – about 10 to 12-th degree. It is because of the number of cells in the human body still continues to operate after alcohol. However, if blockage is not even big and does not seem important vessel, without which human beings and so live, killed hundreds of millions of cells. This omission ingenious creation of nature – the body could not be ignored, but nothing is perfect, and hundreds of thousands of new cells formed under certain conditions – such as a drop in the sea, as at first sight, and millions dead.

How to lose? When the brain is formed an increasing number of "dead zones" (a dead cell, by the way, leave the body naturally), will take effect the so-called compensatory possibilities of the brain – it bypasses the zones by passing pulses (or data) due to other neural networks, and other, respectively, of living cells. The problem is that at some point and these "other" becomes smaller. As a result of deteriorating response, memory, thinking, seeing, possible hearing and the like. Of course, once the reaction gets worse, but it is first of thousands, then hundredths of a second, and so forth, so if you're not an astronaut and pilot of Formula 1, is that you hardly notice.
