(ORDO NEWS) –The new device functions by analogy with neural networks, which form the neurons in the human brain. The operation of a computer is based on an oscillatory chemical reaction, which is similar to cyclic processes in the cells of living organisms.
Scientists say that their neurocomputer would be more correctly called a chemical brain. The behavior of this device under external influence should resemble the behavior of living organisms.
Scientists of the Center for Nonlinear Chemistry of the IKBFU Kant for several years developed neurochemical computer, which is based on a chemical Belousov-Zhabotinsky reaction… It proceeds in an oscillatory mode, while some parameters of the chemical reaction (color, temperature, etc. ) change periodically, forming a complex and uneven space-time structure.
So, scientists Belousov and Zhabotinsky added a clear liquid from a pipette to a glass with a pink liquid, and after a minute the solution in the glass turned blue. A minute later, it turned pink again – a kind of “chemical clock” appeared.
Kaliningrad researchers used this reaction to operate the basic element of a neurocomputer – a micro-oscillator (in other words, cells) about 0.1 mm in size.
Also, the composition of the chemical neurocomputer includes a central rhythm generator, an antenna that receives external signals, readers that determine the current rhythms, and, finally, a decision block. These blocks are made up of cells that are interconnected in a manner similar to neural connections in the human brain.
According to scientists, the behavior of a neurocomputer should resemble the behavior of living organisms. The computer behaves reasonably in the event that it reads data on external influences from the antenna and switches automatically to the mode that is optimal for a particular type of exposure. This is called adaptive behavior.
“We now have the world’s first chemical neurocomputer with adaptive behavior. Perhaps it would be more correct to call this device a chemical brain rather than a computer. The prospects for using such chemical neurocomputers can be fantastic, some of which can even be daunting. However … the practical significance is determined by funding and specific goals, ”says Vladimir Vanag, professor and head of the Center for Nonlinear Chemistry.
