Researchers Simulate Building Block of Rat's Brain

slick_shoes passes on an article in the Guardian about the Blue Brain project in Switzerland that has developed a computer simulation of the neocortical column — the basic building block of the neocortex, the higher functioning part of our brains — of a two-week-old rat. (Here is the project site.) The model, running on an IBM Blue Gene/L supercomputer, simulates 10,000 neurons and all their interconnections. It behaves exactly like its biological counterpart. Thousands of such NCCs make up a rat's neocortex, and millions a human's. "Project director Henry Markram believes that with the state of technology today, it is possible to build an entire rat's neocortex. From there, it's cats, then monkeys and finally, a human brain."

    What? Your post is so wrong I don't even know where to begin.

    First off, why not just use a human brain if you want an identical machine? Well, for sending probes to mars. Or to the depths of the ocean. Or any other place that is too dangerous to send humans, but that a machine could survive in. Even if the brain was a replica of someone's personality, all they'd have to do is find someone who thinks it would be really cool to go to mars, and replicate their brain. It'd be a hell of a lot more intelligent than a traditional AI system at this point.

    Secondly, if we want an AI system that better than the human brain, THIS IS THE WAY TO GO. Figure out exactly how the human brain handles thing that are really hard for computers, like object recognition. Once you've got that, you can replace//add on parts that do things better/faster than humans, like math. In terms of adaptability and general purpose use, NOTHING in AI comes anywhere close to the human brain right now. So trying to make an AI system that is better than the brain, a good first step is to try and make the human brain, then start tweaking that.

    The point is to try and understand how biological brains do what they do, and how we can make computers do those things (which computers currently suck at). Sure, you can emulate basic behaviour in a pre-define environment, but try making a system that can differentiate a food source the 'rat' may never have seen before based on sight and smell in an environment that it's never been in.

    It would be satisfying to resurrect the consciousness of people in the past that you hate, and beat the living @&#%! out of them. The guy who invented neckties and the inventor of the QWERTY keyboard layout come to mind. Put them in Doom and blast 'em up.

      They guy that invented QWERTY did just fine. You are probably just missing his goal. The goal was to slow down typists. With a manual hammer type typewriter, typing too fast jams the machine. You need a way to make sure that 1) the most commonly used letters are farther away from each other, thus reducing the likelihood of jamming, and 2) slow the typist down enough that each hammer has time to retract before the next one comes up and jams it.

      That necktie guy... Yeah, lets run him on Windows ME.

    From the article:

    Markram is banking on Moore's law holding steady, as a computer with the power of the human brain, using today's technology, would take up several football pitches and run up an electricity bill of $3bn a year. But by the time Markram gets around to mimicking a full human brain, computing will have moved on.

    It's amazing how some people want the computing resources to simulate a rat's brain but still can't simulate a honeybee's brain and the resultant behavioral complexity. After all, a bee's brain has only about a million neurons. It could probably be done on a desktop machine and yet, a bee's behavior is amazingly sophisticated. Is it me or does it seem that some people have no clue as to what constitutes intelligence and would rather spend the taxpayer's money on what can only be qualified as useless goals?

    Would it not be much better to implement a downsized version of the human brain (with all the various cortices) and see if it can learn and adapt to the environment? But then again, that would be too much to ask since Markram et al don't have an overall theory of brain operation. It's better to keep your sights as high as possible and have an excuse as to why your artificial brain or cortical column is no more intelligent than a flea: you always need faster and more expensive computers. And more funding. Yeah.
