Scientists have discovered that nano-sized silver wires can communicate with each other like neurons in the human brain. Moreover, the wires were learning and forming memory like the human brain.
It is not possible to imitate the human brain on a non-biological object with today’s technology. But scientists, in their new study, at least the most basic of human cognitive abilities learning and memory. can be imitated on non-biological objects showed.
Using nanowires that are only one-1000th the thickness of a human hair, scientists discovered that the wires begin to learn and remember their previous movements. These wires contain no biological elements, only made of highly conductive silver consisted of.
Teller manages to keep his previous moves in his memory, learning from his mistakes:
It’s pretty unusual to expect anything non-biological to learn or retain something. But in experiments with these wires, the wires responded to electrical signals and formed networks within themselves. Moreover, these established networks reflect what they have done in previous signals. he “remembered” at least 7 steps.
Moreover, these 7 steps are equal to the average number of information that the human brain can hold in its working memory. equivalent was. This number in the human brain, published in 1994 “The magic number seven, plus or minus two: Some limits of our information processing capacity.It was stated in the article titled ”.
But how do strings learn and remember things?
Wires respond just like neurons when given an electrical signal.synapseIt was acting like ports named ‘. But the learning and memory of the strings did not occur on their own.
After the scientists gave the electrical signal, they compared the result they expected to the result of the wire mesh. In the light of the data obtained, the connection points of the wires strengthened or bluntedThus, the desired result was reached.
The memory of the strings was seen by performing the ‘n-back’ test, which is used to measure memory in humans. As part of the test, a series of stimuli was presented to the wire mesh, and with each new stimulus, the previous steps were compared. network at least 7 steps was observed to be repeated in each signal.
The new work of scientists, that physical equipment can also provide learning and memory building abilities. lit up. The research has been published in Science Advances.
