Is it really possible to simulate the human brain on a computer? AI researchers have been investigating that question for decades, but Japanese and German scientists have run what they say is the largest-ever simulation of brain activity using a machine.
The simulation involved 1.73 billion virtual nerve cells connected by 10.4 trillion synapses and was run on Japan's K computer, which was ranked the fastest in the world in 2011.
It took the Fujitsu-built K about 40 minutes to complete a simulation of one second of neuronal network activity in real time, according to Japanese research institute RIKEN, which runs the machine. … Read more
