How does a neurochemical computer work?
Scientists explain that the principle of operation of the device is similar
Futurists always scare their readers with the growingby the power of artificial intelligence (AI), which is based on conventional computer systems. However, AI can be organized in different ways. For several years, the staff of the Center for Nonlinear Chemistry of the Baltic Federal University. Immanuel Kant tried to create a computer based on the principle of the Belousov-Zhabotinsky chemical reaction. Last year, IKBFU researchers proposed a mathematical model for the operation of a neurochemical computer based on a looped chemical reaction. The results of the study of Professor Vladimir Vanag and two graduate students Pavel Smelov and Ivan Proskurin were published in one of the most famous scientific journals Physical Chemistry Chemical Physics.
As the scientists explained, in the process of creationcomputer, the system worked like a small child repeating the actions of the mother. Yes, this behavior still cannot be called meaningful, but this is an example of adaptation to the environment.
How a neurochemical computer worksbased on the interaction of vibrating elements. In this case, different chemical substances play their role, but in microscopic amounts - sulfuric and malonic acids, bromates and catalysts. These elements fluctuate due to the Belousov-Zhabotinsky reaction. In the course of such a reaction, its parameters - for example, color or temperature - change periodically. The simplest example of such a reaction is a color change. The solution may turn from colorless to yellow, and then return to its original colorless state.
What is the Belousov-Zhabotinsky reaction?
In 1951, Soviet chemist Boris Belousov,trying to simulate a metabolic process in laboratory conditions, I discovered something amazing. The solution in which the reaction took place periodically changed its color from colorless to yellow and back. That is, having reached the end, the process began anew. Many scientists considered such a process to be impossible in principle. However, later the biophysicist Anatoly Zhabotinsky reproduced Belousov's experiments and gave an explanation for periodic fluctuations in the solution. Thus, the foundations of nonlinear chemistry were laid.
Advantage and future development
Created today, the first first in the worldThe neurochemical computer has at least one strong advantage over other AI systems. “Such artificial intelligence will be clearer and closer to a person,” says scientist Vladimir Vanag. Its principle of work is surprisingly similar to the work of the human brain.

Professor Vladimir Vanag is also sure thatconventional and neurochemical computers will develop in parallel. Of course, in the future it will be possible to combine both devices into one cybernetic organism. In addition, neurochemical computers are very small, so they can be easily implanted into the body or even taken in pill form. However, so far all these predictions look like fantasy.
