Scientists were able to create an artificial brain in the lab

you Can argue with that, but our brain is really an interesting thing

Here and there flashed information about the fact that a person unique. We know that without information from the media, but they always bring the results of any studies that further confirm this. On the basis of this information it can be concluded that the reproduction of the brain, or impossible, or extremely difficult at the present stage of scientific development. A group of scientists proved the opposite and was able to grow in the laboratory are almost fully functional brain.

The Organelles of the cerebral cortex on special chips that can record the activity for more accurate data without the need for additional complex work. Also minimised the risk of damage to the material, which are inevitable during measurements.

Cell Growth was maintained for ten months, and during that time, scientists have collected a very large amount of interesting data.

How to grow a brain

The Technology of growing of organelles enables the programming of the cells so that they can be grown a small model of the brain. Yes, these brains out very young and can't be a full on, usually, their size is not larger than a pea, but functioning model is almost the same as a real brain.

This artificial brain not only contains typical brain layers of neurons, but has an activity that allows them to understand many of the processes occurring in this fundamental organ.

However, to call this artificially grown brain is not real. It is only up to a point can grow quickly and develop as it develops a real brain. After a certain point he runs out of food , which is normally provided by blood vessels. As a result, after a certain point, the artificial brain fails to reproduce the processes that are being studied by scientists.

Communication in the brain — that's what makes him the center control

How the brain is active

The Initial signs of activity of an artificial brain are manifested at the end of the second month of growth. Over time, activity becomes more difficult which corresponds to the growth and development of the living brain. Upon reaching the ten-month ”age” activity of grown sample is very similar to the brain activity of a human embryo through 10-16 weeks after conception.

Such studies and the cultivation of brain cells have been carried out earlier, but only now scientists have been able to do it so accurately and precisely that the activity of cultured neurons was similar to that in preterm infants. This similarity was perhaps due to the fact that neural connections over time, and rebuilt, changing its structure, has acquired a large number of cells began to communicate with each other. In the end, the ”brain tubes” similar to the human with the diversity of neurons and their electrical activity.

The Researchers analyzed 15990 , which had been one of the basic classes:

the

Progenitor cells the

• intermediate cells

Glial cells the

• glutamatergicakie cells
the
• GABAergic cells

The Last commonly found in the cerebral cortex of primates, but as the experimental cells not only rebuilt, but also changed their relationship. It is typical for brain development during maturation.

How do scientists explore the brain

To retrieve the results of the study, researchers 4 times in 10 months and collected samples for RNA-scan. So they studied the activity, characteristic for different types of nervous tissue.

a Little idealized image of the brain, but it looks nice

As mentioned above, the organelles were grown on special multielektrodnaya chips. The only way to gather information about neural activity without damaging the cells. Chips capture electrical impulses and record them in the form of EEG (electroencephalogram).

The Human brain as a result of growing up a little change in the type of EEG. The point is simple — the older the brain, the less pause between the flashes of neuronal activity. The chips, which were grown organelles, recorded similar activity.

To make sure that the brain really can be studied on the basis of the organelles, scientists have tried to learn how to determine their age at EEG. For this help, as usual, encouraged . They are taught to determine the age of a person by an EEG, then offer to work with the grown samples. As a result, they received additional confirmation that the organelles develop in the same way as a real brain. Particularly well the network handled more ”adult” samples.

always aroused the interest of scientists

Why you need an artificial brain

Based on the fact that scientists do not just create an artificial brain that can work as a real, but confirmed that the method is not an error, we can say that we got a great tool for learning our main body.

Not everyone will understand but many will remember

This method of research will allow you to obtain much more information without the need of studying human samples. In addition, to the artificial brain you can apply some research methods that are not applicable to humans. You can even create a fabric with to explore how they affect the development of man and mankind in General. In interesting time we live in. Agree?
