Artificial intelligence systems process information like the human brain. However, many of the mechanisms by which the human brain works are still undiscovered. Japanese researchers report that they have succeeded in creating an artificial analog of the brain.
One of the unsolved problems is understanding how to remember, learn, and forget information. The researchers say that the difficulty lies in manipulating the living brain in experimental conditions. That is why a neuromorphic network was created, as close as possible to the real brain. It is a "tangle" of ultra-thin silver nanowires coated with an insulating polymer. Due to the migration of silver atoms through the polymer coating, about 10 million connections have emerged, similar to neural synapses, which provide connection and exchange of information between brain cells. The area of the device is only 10 square millimeters.
Using the resulting neuromorphic network, the team was able to reproduce electrical processes similar to those that occur in the brain during memorization, learning, forgetting, waking and sleeping. Further study will allow us to better understand how all this works and how the human brain works, which will allow us to influence its work.
According to scientists, the device is constantly evolving and comes up with unique behaviors, which is very similar to how the human brain behaves. They hope to design a fundamentally new memory device, the main feature of which will be the speed of decision-making.
