A microscope can show you the brain’s individual cells, which are connected with “wires” when you examine it. These connections are biogical and send electric impulses.
Although this arrangement isn’t like a smartphone’s computer chip, it seems that the purpose of the arrangement is to move information around and learn.
To create a neural net, we can mirror the network of neurones on a machine. Artificial neural nets can be used in computer science to recognize and learn.
