According to neuroscientist Professor Henry Markram of Switzerland in Brain Mind Institute. A model in which that duplicates the functionality of the human brain is possible approximately in 10 years.
In recent studies, the perceptible intricacy of human brain is not an obstacle to build a “imitation” brain which is stated by Professor Markram. He stated that, “The brain is of course extremely complex because it has trillions of synapses, billions of neurons, millions of proteins, and thousands of genes. But they are still finite in number. Today's technology is already highly sophisticated and it allows us to reverse engineer the brain rapidly.” He made a sample already which has a capability that robots recently can does screenings and planning tens of thousands of times quicker than individual scientists or either technicians.
