Mouse brain simulated on computer

BlueGene L under construction, IBMU.S. researchers have simulated half a virtual mouse brain on a supercomputer.

The scientists ran a “cortical simulator” that was as big and as complex as half of a mouse brain on the BlueGene L supercomputer.

In other smaller simulations the researchers say they have seen characteristics of thought patterns observed in real mouse brains. Now the team is tuning the simulation to make it run faster and to make it more like a real mouse brain.

Half a real mouse brain is thought to have about eight million neurons each one of which can have up to 8,000 synapses, or connections, with other nerve fibers.  The vast complexity of the simulation meant that it was only run for ten seconds at a speed ten times slower than real life – the equivalent of one second in a real mouse brain.
