Brain model may help build human-like robot

It goes without saying that the human brain is complex, and would be hard to build from scratch. But researchers are looking to simulate how the brain works so that more human-like artificial intelligence can be created and we can better understand damage to our own brains.

Chris Eliasmith of the University of Waterloo in Ontario, Canada, led research published in the journal Science on a brain model called SPAUN - the Semantic Pointer Architecture Unified Network.

SPAUN lives inside a computer, can view images with a camera-like eye and can draw responses to questions. For example, show it the number "4" and it will write its own "4." It can even mimic the style of the numeral.

He was asking for ordinary folk to submit a video application for a spot on the upcoming team.
