(credit: Ohio State University Wexner Medical Center/ Batelle ) With a paralyzing spinal cord injury, the biological wiring that hooks up our controlling brains to our useful limbs gets snipped, leading to permanent loss of sensation and control and usually a lifetime of extra health care. Researchers have spent years working to repair those lost connections, allowing paralyzed patients to sip coffee and enjoy a beer with robotic limbs controlled by just their minds. Now, researchers have gone a step further, allowing a paralyzed person to control his own hand with just his mind. In a study published Wednesday in Nature, researchers report using a “ neural bypass ” that reconnects a patient’s mental commands for movement to responsive muscles in his limbs, creating somewhat of a synthetic nervous system. The pioneering patient, Ian Burkhart, a 24-year-old man left with quadriplegia after a diving accident almost six years ago, can once again move his hand. In the pilot study he could control movement of individual fingers, grasp big and small objects, swipe a credit card, and play Guitar Hero . The advance may open the door to restorative treatments for paralyzed individuals, allowing them to have independent movement—and lives. Read 10 remaining paragraphs | Comments
