Artificial brain is composed of 40 to 60 nerve cells taken from rat brain hippocampus. Researchers develop these organs by attaching the protein layer and the silicon discs, then added brain cells from embryonic mice.
Layers of proteins into the medium for the growth of brain cells that intertwine with each other produces a ring-shaped brain nerve tissue.
After connecting nerve cells, researchers examined the response of organs by passing an electric current. The result, electric shock could be around the nerve tissue and survive for 12 seconds. This figure far exceeded expectations since the original estimate shows an electric pulse only lasted for a quarter second.
Memory is short on nerve cells work almost like a long memory in humans and animals. The principle of working memory is long enough to save the stimulation of neural tissue even though the stimulus is gone.
"Unlike other cells, nerve cells connected to each other and rely on these networks. The function of a single nerve cell can be different if they form a network," says Head of Research Team of the Department of Biological Engineering, University of Pittsburgh, Henry Zeringue, on the campus page.
Zeringue research has not been completed. He and his colleagues will continue to develop artificial brain is larger and more complex so that it can reveal how the human brain to send signals and store information effectively. "We can trace the process of remembering in humans."
