German surrogate human brain
The work of the human brain is still irreplaceable as one enjoys and the other is tired. There are also some who put their brains at 100 percent to create an artificial substitute for this valuable organ. To what extent will the computer replace the human mind?
The human brain weighs an average of one and a half kilograms and although it is more than three times smaller than the brain of an elephant, it makes the researchers a real problem. The mysterious, still unrecognized by the science of the action of the key human body, makes it the only organ devoid of its artificial substitute.
The largest "computer brain" in the world is located in the RIKEN Japanese Advanced Technology Research Center in Kobe - it's a supercomputer K with 82,944 processors and one petabyte of memory, equivalent to a computing power of 250,000. Home computers. In July this year. Japan neuroscientists came from Japan from one of the largest interdisciplinary research centers - the Jülich Research Center. Fusion with Japanese researchers and their equipment has resulted in a remarkable experiment - scientists have assumed they will be able to simulate a 1 percent job. Human brain area, which is 1.73 billion neurons connected by about 10.4 trillion synapses. In order to carry out the calculation of such a giant cellular network they used open source software - NEST. For the supercomputer K, this meant forty minutes of "exhaustive" work, with each synaptic representing 24 bytes. The experiment was a complete success, immediately gaining the most spectacular computer test in the history of science. Project enthusiasts quickly calculated that sixty six hours of Supercomputer K would be enough to simulate one second of brain work. Project coordinator Markus Diemann said that in the next decade we will be able to simulate the entire brain with exaggerated computers.
The glitter of big numbers and computational fireworks is overshadowed by the fact that the human brain remains a great unknown. Participants in the project themselves acknowledge that the meaning of their experiment was to demonstrate the feasibility of using available technology today. The basic problem remains invariably the understanding of the principles of the brain, because without this comprehensive knowledge the construction of its computer counterpart is impossible.
It does not, however, capture the importance of the German-Japanese experiment, which will not only be able to indicate new paths to get to know the most enigmatic organ of our body, but also, Kenji Doya of RIKEN will contribute to the advancement of medicine focused on investigating the mechanisms of Parkinson's disease.
If research on the human brain continues at a similar pace, we can soon expect a truly (r) evolutionary jump.
