'Neural Bypass' Links Brain To Hand To Get Around Paralysis
An anonymous reader writes: People who are paralyzed from a spinal cord injury still generate movement commands in their brains, but those commands can't travel down their spinal cords and peripheral nerves to reach their muscles. So biomedical engineers came up with a "neural bypass" to route brain signals around the roadblock. The system has just been demonstrated by a human patient for the first time. The patient has a brain implant to record signals from his motor cortex which are sent to a computer, where a decoder algorithm figures out which signals correspond to which specific imagined movements. It then sends a command to a sleeve of electrodes the patient wears on his forearm, which stimulates his muscles in precise patterns to produce the desired hand movement. The patient has already poured from a bottle, stirred with a swizzle stick, swiped a credit card, and played Guitar Hero.Read more of this story at Slashdot.
