I listened a presentation today by some scientist who runs a swiss institute working on “reverse engineering the brain”. Go figure. I didn’t understand everything he said, and probably he didn’t say much either. But I got some numbers.
Brain runs at one petaflop/second speed (http://www.petaflop.info/). It is 10 to the 15th power operations a second, or it is million times billion operations. There is no computing power yet at this speed, but IBM and CRAY are working on it. If a computer would be build with same power now, it would take up 450 sq. meter and would need 3 million watt power. But the brain takes up 0.01 sq. meter and needs 60 watts power. Brain has a million kilometer fiber connection and 100 billion neurons. He actually showed a neuron simulation on a computer..
He expects that in 2015, there will be a computer capable of 1000 petaflops/second and 200 petabyte memory. That will enable to simulate the brain in real time.
Ok what I got from this is that we are nowhere near to understand and comprehend the brain yet, and may never will... Just amazing...
