Intervention in the brain

In the ancient world he lived was a glorious hero Odysseus. With his friends, he went to the glorious feats on a beautiful ship Argo (with reinforcements from other ships). That the ship was the basis of a curious debate. Like, if you put it under the dome of the museum, the board of the ship will rot. Sooner or later, they will have to change. And when the last board "old ship" will be replaced by a new, whether this ship is the same?

A similar situation can be observed in the reasoning in the field of nanotechnology. When the last cell of the man will be replaced by an artificial, whether it is the old man? The answer is not so quick and easy.

The human body is constantly changing. Full upgrade of all the tissues takes approximately seven years of life. Fourteen-year teenager has neither a common cell with a seven-year old. And to this we treat normally. Such a long period (7 years) eliminates the radicalism of the changes and allows you to adjust how the teenager to physiological changes and the world, to the changes of the teen.

But these changes will not notice in the course of life. They are uniformly and confirmed by evolution. The entire human species took a couple such changes and so we treat them as givens.

In the work of our body has two basic principles. This body structure and its function. Fabrics replace each other, continuing to perform certain functions, without changing the essential structure of the body. Otherwise, such cells fall into the category of "dangerous" and or controlled by, or are destroyed.

Technological intervention into the body, looks radically. A single replacement of major tissue of the body, is too striking and unusual for the body. This is justified some loss of body parts, but not as a voluntary rejection of them. Only with the full simulation of living cells, such intervention is permissible. Is it possible now? It is difficult, but feasible at great expense. Is it really bring in the future? Rather, what we assume.

It is one thing to change the body's tissues, and quite another - to be implemented in the brain. A man whose brain is 50%, and one cell mechanical, whether to remain human? No, it will not. He will present a transhuman (trans man) transitional form of evolution, for better sight. Provided that artificial cells would not just copy job "native" brain cells, but also to perform it more effectively. Will it affect the psyche? Just in case, if the difference in perception, signaling and other accompanying moments will be significantly different from the usual for us.

As a result of this intervention, we get a better person than before. A "best", there is always the enemy of "good".
