Mind-operated robot arm helps paralyzed woman have her cup o' joe (video)
Researchers at the Braingate2 consortium have made a breakthrough that allows people with spinal cord or stroke injuries to control robotic limbs with their minds. The original project allowed subjects with motor cortex-implanted chips to move cursors on a screen with their minds, but they can now command DEKA and DLR mechanical arms to grasp foam balls and sip coffee. Researchers noted that dropped objects and missed drinks were frequent, but improved brain sensors and more practice by subjects should help. To see the power of the mind move perhaps not mountains, but good ol' java, jump to the video below.
Ekso Bionics' exoskeleton used to let paraplegics walk (video)
It's not just nuclear-powered super soldiers who will use exoskeletons -- it can also be used to help those with physical disabilities. The Kessler Foundation grabbed one of Ekso Bionics' Ekso units and gave six people with severe spinal injuries, including a tetraplegic, the chance to walk. It's part of a trial study to examine the effects of walking for wheelchair-users, to see if it's better for their overall health or if it could contribute to their rehabilitation. A wider study will begin early next year with the hope of expanding use of the gear to domestic situations in the future. After the break we've got video of the people walking for the first time since their injuries and it's hard not to find yourself feeling a little emotional at the sight of it.
BrainGate hits 1,000 day mind-control milestone, nearly three years of pointing and clicking
Aspiring Svengalis rejoice! For BrainGate has reached a significant landmark in computational thought-control -- the 4 x 4-mm implantable chip has given a woman with tetraplegia the ability to point and click with her brain for 1,000 days. An article recently published in the Journal of Neural Engineering said the woman, known simply as S3, performed two easy tasks every 24 hours, using her mind to manipulate a cursor with 90 percent accuracy. Each day she was monitored, S3 would post up in front of a computer and continuously command the thing with her thoughts for 10 minutes. Functionality reportedly deteriorated over time, but the paper points to the chip's durability, not sensor-brain incompatibility, as the culprit. Research is currently underway to incorporate BrainGate into advanced prosthetics that could get tetraplegics like S3 up and moving again. Now, how's that for the power of positive thinking?
