Simulating a neuron day in a second

According to ACM TechNews

So far, a prototype chip has been developed that replicates about 300 neurons and a half million synapses. The researchers used a combination of analog electronics to represent the neurons and digital electronics to represent the communications between the neurons. Because the chip’s neurons are so small, the system runs 100,000 times faster than the biological equivalent, and 10 million times faster than a software simulation. “We can simulate a day in one second,” Meier says. The researchers are now working on a network of 200,000 neurons and 50 million synapses that will incorporate several neuroscience discoveries.
