Canadian Scientists Develop Most Complex Human-Like Brain Simulation

By Rob Schwarz on November 30, 2012 at 9:03 am

Scientists at the University of Waterloo in Canada have successfully created the most complex simulation of the human brain ever.

Called the Semantic Pointer Architecture Unified Network, or Spaun, the software consists of 2.5 million simulated neurons, and can recognize images, numbers and handwriting by simulating various neural activities of the human brain. Unfortunately, it can’t learn anything new, yet (though it can remember).

Despite having a relatively low number of simulated neurons, it’s the most “human-like” brain simulation developed to date. This is because Spaun allows scientists to see the emergence of complex behavior and processes from relatively simple tasks.

Spaun also suffers many of the same limitations humans do:

“…[Spaun] has trouble remembering lists of numbers when they are too lengthy, and is better at remembering numbers at the beginnings and ends of lists. It also hesitates before answering questions, just as humans do.” – Spaun, the new human brain simulator, can carry out tasks, Phys.org

The simulation is able to “see” using an external “eye” (read: camera), and can respond to images — the aforementioned numbers, letters, etc. — by drawing with a robotic arm.

Updates are already in the works to give Spaun the ability to learn new tasks and even respond to positive or negative stimulus.

But you know, things like this always make me wonder.

What is consciousness? At what point will we create brain-like software, switch it on, and be met with an actual, conscious being? What will that be like?

Will we even recognize it as conscious?

    If and when we get consious brain AI we will again have a battle of equality between intelligent beings. The new hate will be shown towards those “robots” that feel like they are consious and as or more intelligent then a human and should be treated as such. It will be an interesting time indeed.

      Agreed. We’re going to face same very compelling issues in the future.

      Thanks for your comment.
