I want the robot arm to do a digital stim, not play games. I'd love to show the folks from the news what is really practical..lol   john     In a message dated 7/12/2006 4:18:30 PM Eastern Daylight Time, [EMAIL PROTECTED] writes: http://www.newscientisttech.com/article.ns? id=mg19125606.200&feedId=health_rss20 Overcoming paralysis is a case of mind over matter 15 July 2006 Celeste Biever Magazine issue 2560 A MAN paralysed from the neck down by knife injuries sustained five  years ago can now check his email, control a robot arm and even play  computer games using the power of thought alone. Matt Nagle's  extraordinary abilities first grabbed the headlines in March 2005.  Now details of the technology that lets him perform these and other  tasks are published in Nature this week (vol 442, p 164). Electrodes implanted in Nagle's brain measure the neural signals  generated when he concentrates on trying to move one of his paralysed  limbs. Software trained to recognise different patterns of neural  activity then translates the attempted gesture into the movement of  an on-screen cursor or a robotic arm at Nagle's side. "The  fundamental findings are that you can record activity from the brain  years after injury, that thinking about movement is sufficient to  activate the brain, and that we can decode the signal," ...
