Spaun brain simulation

Last updated: Dec 1, 2012

Spaun is, as of December 2012, the world's largest functional brain model. It is a simulated brain that contains 2.5 million neurons. This is far fewer than the 86 billion in the human brain, but enough to recognize lists of numbers, do simple arithmetic, and solve reasoning problems.

The system is biologically realistic in its simulation of spiking neurons and neurotransmitters. As a result, it reproduces many quirks of human behaviour, such as the tendency to remember items at the start and end of a list better than those in the middle.

Spaun - the Semantic Pointer Architecture Unified Network - was created by Chris Eliasmith and colleagues at the Centre for Theoretical Neuroscience (CTN) at University of Waterloo in Canada.
