Human Brain

The human body is one of the most amazing things God ever built. I think He enjoys us learning about its design, because we keep discovering just how complex it really is. The article below that I have partially quoted from is about researchers trying to simulate the human brain. They are starting with a mouse brain (3,500 times less complex) and finally were able to do what it does in 6 times the time. And to do so, it is "leveraging IBM's technical resources to the limits". How great is our God!

From the article...

Their first goal is to build a "massively parallel cortical simulator" that re-creates the brain of a mouse, an organ 3,500 times less complex than a human brain (if you count each individual neuron and synapse). But even this is an undertaking of epic proportions. A mouse brain houses over 16 million neurons, with more than 128 billion synapses running between them. Even a partial simulation stretches the boundaries of modern hardware. No, we don't mean desktop hardware. We're talkin' supercomputers.

So far, the team has been able to fashion a kind of digital mouse brain that needs about 6 seconds to simulate 1 second of real thinking time. That's still a long way from a true mouse-size simulation, and it runs on a Blue Gene/L supercomputer with 8,192 processors, four terabytes of memory, and 1 Gbps of bandwidth running to and from each chip. "Even a mouse-scale cortical simulation places an extremely heavy load on a supercomputer," Modha explains. "We're leveraging IBM's technological resources to the limit."
