Wow, today’s top supercomputers have formidable speed and computational power to rival humans. On the other hand, wow, the human brain is more powerful than today’s supercomputers, which with all their calculations, cannot surpass the complex wonder called the human brain. Scientists note that the brain, the basis of behavior and mental activity, is where over 50 billion neurons communicate with each other, in a network of complexity that some called “unimaginable.” Each individual neuron’s performance depends on molecular structures and mechanisms, and connections and spatial location in the brain.


A team of scientists from institutions in Japan and Germany have proven both “wows” are true. A report in this week’s The Telegraph discusses the feat of a team from Japan and Germany who carried out a record simulation of the human brain, in the largest neuronal network simulation to date—and yet achieved a model of only one second of human brain activity, and taking the computer 40 minutes to do so. Consider: a single second’s worth of activity took one of the world’s largest supercomputers 40 minutes to calculate, and involving just one per cent of the neuronal network in the human brain. The joint project was carried out by the Japanese research group RIKEN, the Okinawa Institute of Science and Technology Graduate University and Forschungszentrum Jülich, a Germany based research center,
