Reverend AtheiStar Posted June 19, 2006 Share Posted June 19, 2006 http://www.spacedaily.com/reports/Mind_Ove...ce_Fiction.html Mind Over Matter No Longer Science Fiction by Marlowe Hood Paris (AFP) Jun 14, 2006 Sitting stone still under a skull cap fitted with a couple dozen electrodes, American scientist Peter Brunner stares at a laptop computer. Without so much as moving a nostril hair, he suddenly begins to compose a message - letter by letter - on a giant screen overhead. "B-O-N-J-O-U-R" he writes with the power of his mind, much to the amazement of the largely French audience of scientists and curious onlookers gathered at the four-day European Research and Innovation Exhibition in Paris, which opened Thursday. Brunner and two colleagues from the state-financed Wadsworth Center in Albany, New York were demonstrating a "brain computer interface (BCI)," an astounding technology which digitalizes brain signals emitted as electrical impulses - picked up by the electrodes - to convey intent. While no spoons were bent, this was definitely mind over matter. Without recourse to nerves or muscles, BCI "can provide communication and control to people who are totally paralyzed" and unable to unable to speak or move, explains researcher Theresa Sellers, also from Wadsworth. Dr. Sellers estimates there are some 100 million potential users of BCI technology worldwide, including 16 million sufferers of cerebral palsy, a degenerative brain disease, and at least five million victims of spinal cord injury. Another 10 million people have been totally paralyzed by brainstem strokes, she said. Scientists have been experimenting with ways to translate thought directly into action for nearly two decades, but BCI has only recently begun to move out of the laboratory and into the daily lives of those trapped inside bodies that no longer respond to their will. Possible applications extend beyond the written word into physical movement - it is only a matter of time, Sellers says, before the same technology is used to operate motorized wheel chairs. "We can do already. But it is a complex problem, and for now it would be unsafe," she says. The frightful condition of being "locked in" came into the public eye in the late 1990s, when French journalist and Elle Magazine editor Jean-Dominique Bauby, after suffering a massive stroke, painstakingly "dictated" a beautiful and moving memoir by blinking his left eyelid. "The Diving Bell and the Butterfly," published two days before he died, became an international bestseller. Had BCI technology been available to him, Bauby would almost certainly have been able to write his book unassisted, and in a fraction of the time. The Wadsworth system, one of several that detects electroencephalographic (EEG) activity, is based on an algorithm that analyzes the brain waves and identifies peaks in activity that correspond to particular mental efforts. As Dr. Brunner concentrates on the "B" of "bonjour" in a keyboard-like grid of letters and symbols taking up half the screen, a computer randomly highlights lines of characters in rapid succession. Each time the row - vertical or horizontal - containing the letter "B" is illuminated, Brunner's brain emits a slightly stronger signal. It takes the computer about 15 seconds to figure out what letter he is looking at. The system is doubly adaptive, with both the software and the person using it becoming more efficient over time. "It may not sound very practical, but for someone who is paralyzed it can make all the difference in the world," says Sellers. Indeed, for at least one 48-year old neurobiologist in the United States stricken with amyotrophic lateral sclerosis - an invariably fatal degenerative disease that attacks nerve cells - the Wadsworth BCI technology has make it possible not only to communicate but to continue working, even though he can no longer even move his eyes. "He writes grant proposals, sends e-mails and can use the keyboard of a computer at home," Sellers said of the man, whom she did not identify in order to protect his privacy. He even wrote a message for the exhibition in Paris, which Sellers projected onto a screen. "To Altran," he began, referring to the French innovation consulting firm that sponsors an annual competition for public service innovation, won in 2005 by the head of the Wadworth Center, Jonathan Wolpaw. "I am a neuroscientist wHo couldn't work without BCI," the message read, typo and all. "I am writing this with my EEG courtesy of the Wadsworth Center Brain-Computer Interface Research Program."

Lycorth Posted June 19, 2006 Share Posted June 19, 2006 Fascinating - I've been wondering when we'll hear tell of such technology being developed... Link to comment Share on other sites More sharing options...
trashy Posted June 19, 2006 Share Posted June 19, 2006 I've always told my wife that I'll need something like that if I ever become incapacitated or immobile like that. I enjoy talking too much. I would go insane without it! Link to comment Share on other sites More sharing options...
Reverend AtheiStar Posted June 19, 2006 Author Share Posted June 19, 2006 Fascinating - I've been wondering when we'll hear tell of such technology being developed... I've read about this technology but it wasn't quite as advanced as a simple cap you put on your head. That's where the real innovation has come. It used to be quite invasive. Now, anyone could do it. Maybe, if the price comes down, it could serve as a remote or a controller for your Xbox! lol... Hell, you could have all your appliances hooked up. No more clapping to shut things off, no more remotes, no more switches, no more anything -- just think it and it shall be done. Sounds really, really lazy! lol... I've always told my wife that I'll need something like that if I ever become incapacitated or immobile like that. I enjoy talking too much. I would go insane without it! It sure beats the whole blinking = typing method! Yikes! Link to comment Share on other sites More sharing options...
sonofspong Posted June 29, 2006 Share Posted June 29, 2006 Sounds really cyberpunkish to me. Now all we're gonna need is a everyone dressing in black leather, and a bunch of all powerful evil megacorperations. Link to comment Share on other sites More sharing options...
Megara Posted June 29, 2006 Share Posted June 29, 2006 Sounds like it has a lot of potential. It'll probably be incredibly expensive though. Link to comment Share on other sites More sharing options...

I don't like the smell of it. It stinks. I might wear some black vinyl, though, just for the effect! lol... Link to comment Share on other sites More sharing options...
