A team of chemical engineers figured out how to grow a self-assembly circuit that resembles the structure and electrical activity of parts of the brain. This is a continuation of the beloved project of the scientist James Giemsewski from the University of California at Los Angeles, who announced back in 2012 that he wanted to create a synthetic brain. “Giving intelligence, thoughts and knowledge a physical form” to launch a new technological revolution.
In their experiments, Giemsewski’s team created a structure of tightly packed copper pillars, which, when treated with silver nitrate, began to “grow” thin fragments, similar to nanowires. At first glance, their arrangement was chaotic, but when studied at the atomic level, it became clear that a bond was formed between two separate nanowires. This resembles the structure of synapses in the human brain. And the density, as well as the order in which such bonds are formed, are not at all random.
If you act on this structure with an electric current, then some of the bonds will be destroyed, and others will appear in their place. By changing the parameters and points of application of the current, one can force the “brain” to form the desired architecture of synapses, which can then be “read”. That is, this is a kind of memory, which, according to the principle of its functioning, really remotely resembles the work of the human brain.
There is still a long way to go before a full-fledged “thinking” brain is created, Giemsewski said. However, the basis, the platform is already there. This structure exhibits electrical characteristics that are very similar to functional MRI of the brain. The artificial intelligence of the future does not have to be digital in nature, as many believe, there is a chance to create “synthetic intelligence” in other ways.
