Given a map of all (or most) of the neurons in a functional human brain, and a good understanding of how a single neuron works, it is theoretically possible for a computer program to simulate the working brain over time. If you add some method of communication, this simulated brain might then be shown to be fully intelligent.
For example, in 2005 the Swiss Brain and Mind Institute of the École Polytechnique started the Blue Brain Project. It's an attempt to create a synthetic brain by reverse-engineering the mammalian brain down to the molecular level. Using an IBM Blue Gene supercomputer, the simulation does not consist simply of an artificial neural network, but involves a biologically realistic model of neurons.
It simulates a single neocortical column consisting of approximately 60,000 neurons and 5 km of interconnecting synapses. The goal, which is to simulate a human brain, could be achievable in as little as 10 years time.
I also heard that too. You are might be right.I've read some time ago that the size of human memory is estimated more than 100 petabytes (1Pb = 1024Tb = 1048576 Gigabytes), and I agree with this estimation.
But correct me if I am wrong Int 29AH, in 1986, Dr. Thomas K. Landauer, professor at the Department of Psychology of the University of Colorado and former manager of an information science and human-computer interaction research group at Bell Laboratories and Bellcore, concluded that the brain held about 200 megabytes of information.
He got this number partly by looking at the rate at which people could take in information, both by reading and by looking at pictures. He also studied estimates of the rate at which people forget things, and the amount of information adults need in order to do the tasks they normally do.
His numbers (expressed in gigabits, not gigabytes), were 1.8, 3.4, 2.0, 1.4 and .5 gigabits. Averaging these and dividing by 8 yields 227 MB. Since there are between 10e12 and 10e14 neurons, this suggests that the brain contains 1,000 to 100,000 neurons for each bit of memory. Of course, much of the brain is used for perception, motor control, and the like.
Besides, Teradata Corporation's Database 12 has a capacity of 50 petabytes of compressed data. AT&T has about 16 petabytes of data transferred through their networks each day. Google processes about 20 petabytes of data per day.
