New neural interface restores severed spinal connections without wires
People suffering from spinal cord injuries could soon have another treatment option at their disposal -- one that doesn't involve strapping themselves into a mechanical exosuit. Rather than hardwiring an electronic bridge into a patient's back, a new neural interface bypasses the damaged spine's air gap and transmits motor signals from the brain to the legs wirelessly.
Graphene key to promising treatment for spinal cord injuries
Graphene seems to have almost limitless potential, from making better batteries to night-vision windshields and microscopic sensors. And now, a team at Rice University has shown the material could be key to a promising new treatment for severe spinal cord injuries.
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.
Paralyzed man can stand and walk again, thanks to spinal implant
Here's an amazing story to end your week on a high note: a 25-year-old paraplegic is now walking again, thanks to a groundbreaking procedure developed by neuroscientists at the University of Louisville, UCLA and Cal Tech. The Oregon man, Rob Summers, was paralyzed below the chest in 2006, after getting hit by a speeding car. This week, however, doctors announced that Summers can now stand up on his own and remain standing for up to four minutes. With the help of a special harness, he can even take steps on a treadmill and can move his lower extremities for the first time in years. It was all made possible by a spinal implant that emits small pulses of electricity, designed to replicate signals that the brain usually sends to coordinate movement. Prior to receiving the implant in 2009, Summers underwent two years of training on a treadmill, with a harness supporting his weight and researchers moving his legs. This week's breakthrough comes after 30 years of research, though scientists acknowledge that this brand of epidural stimulation still needs to be tested on a broader sample of subjects before any definitive conclusions can be drawn. Summers, meanwhile, seems understandably elated. "This procedure has completely changed my life," the former baseball player said. "To be able to pick up my foot and step down again was unbelievable, but beyond all of that my sense of well-being has changed." We can only imagine.
