One step forward to the Ghost in the Ghost injury, succeeded in creating a computer circuit with brain cells

The reliability of one neuron constituting the human brain is actually low, and the signal is transmitted to another neuron only 40%. In this way, despite its low reliability, the human brain makes it more reliable by combining these neurons extremely.

That means that if you combine several neurons it will work properly as a computer circuit? A researcher who considered it succeeded in creating a computer circuit using this brain cell at last in the laboratory.

Details are as below.
Computer circuit built from brain cells - tech - 23 October 2008 - New Scientist Tech

This was accomplished by Mr. Elysa Moses of the Weizmann Institute of Sciences in Rehoboth, Israel and its students and developed a method to control the neuron growth pattern that builds reliable circuits using neurons rather than wires I heard he did.

The starting point of this study is a glass plate covered with cell repulsive material, the pattern of the circuit is built in this coating and covered with gentle adhesive on the cell. Because on this plate cells can not build a foothold for growth, they will grow only in pre-built areas. The path drawn in this way grows in one way, so researchers seem to be able to create a device acting like an AND logic gate which outputs only when two inputs are made.

This is the device acting like the AND logic gate


As a result, neurons that had only 40% confidence achieved 95% reliability.

What is made possible by this is that "the brain cell logic circuit may serve as an intermediary between the computer and the nervous system," and said, "The middle of the in vitro neurons that connect between people and the machine It is likely to become a layer ". In other words, connecting the human and the machine, controlling the arm of the robot,ghost in the ShellIn the "EnactmentIt may be useful for.
