Scientists make a 'true' neural network using brain-like chips

Many people have built brain-like neural networks that can learn on their own, but they're typically using plain old silicon to do it. Wouldn't it be better if the chips themselves were brain-like? A mix of Italian and Russian researchers might help. They've created a neural network based on plastic memristors, or resistors that remember their previous electrical resistance. Since they effectively work like brain synapses, they're ideal for creating "true" neural networks where signal transfers create long-lasting effects.
