Supercomputer takes 40 minutes to simulate 1 second of brain activity

A Japanese supercomputer has simulated a single second of human brain activity, but it took the computer 40 minutes to calculate it. The purpose of the exercise wasn't to create simulated brain activity, however, but was to test the capabilities of the fourth most powerful computer in the world, the K computer. Researchers from RIKEN, the Okinawa Institute of Science and Technology Graduate University, and research center Forschungszentrum Julich used the open-source Neural Simulation Technology to simulate 1.73 billion nerve cells linked by 10.4 trillion synapses, representing just 1% of the brain's neuronal network.
