This is seriously awesome. Researchers working with one of IBM's supercomputers were able to model a mouse brain and run it at 1/10 speed. Unfortunately our modern hardware still falls short of the computational capacity of a brain, so I guess we have to start small and start slow. However, this opens up a huge new door into both artifical intelligence and understanding the brain. The next question is, once a brain has been modeled, how do you program it? What is a computer mouse brain capable of doing? If you speed it up, will it just be faster or will be it smarter?
