The Spiking Neural Network Architecture (SpiNNaker) machine can perform 200 trillion actions per second. Each chip has 100 million parts.
The goal is to continue to scale up by 1000 times and simulate one billion biological neurons in real time. A mouse brain has about 100 million neurons and the human brain is 1000 times bigger than that.
They are simulating a section of the brain called the Basal Ganglia. This is the area affected in Parkinson's disease.
