IBM has created the biggest artificial brain which is a simulator run by a 147,456 processor supercomputer, yet the compilation is nowhere near a human brain’s real simulation and is only as good as a cat’s brain. Developed by IBM’s Almaden research center, this artificial brain setup is done in 1.6 billion virtual neurons connected by 9 trillion synapses, which make this almost a cell-by-cell simulation of the human visual cortex.

This IBM’s computer simulation may only be as large as the cat’s brain, yet consuming million watts of electricity and over 150,000 gigabytes of memory, but is way better than the smaller rat brain simulator that IBM managed about two-year ago. This artificial brain which is to be announced at the Supercomputing 2009 conference in Portland, Ore, may be taken as an affirmative that manufacturers will someday manage to build a simulator perfect to replicate the human brain.
With computer systems as vivid and categorically as powerful as this, a new track could be paved for better computers, robots and medical device that could be far more intelligent, sensible and real to coexist in the natural world. The IBM’s brain simulation can reach the ultimate computer mimicking of the entire human cortex, if they can muster about 1000 times more computing power than what they have managed presently. And if Dharmendra Modha, the Almaden computer scientist is believed "This is not just possible, it's inevitable.” "This will happen." In about a decades from now.
