Biological simulation

Faced with uncertainty over how or even if it is possible to create true artificial intelligence, a method of last resort might be the direct simulation of every aspect of the human brain. That is, building a computer model that matches the human brain in every chemical reaction, every electrical signal and every neuron connection

While no groups are seriously considering embarking on such an ambitious project as an approach towards artificial intelligence, there is significant interest among neuroscientists in building powerful models of the brain. The Blue Brain project is a notable attempt to perform large-scale and detailed simulation of 10,000 neurons in a rat’s sensory column. It will, of course, take many decades of research into the human brain and improvements to computers before this might be possible for emulating the more than 100 billion neurons in the human brain.
