Positive thinking

Ioannis Dimitrios Zoulias, University of Reading   Someone in the world suffers a spinal cord injury every one to two minutes , often leading to irreversible and life-changing loss of movement and feeling. But two research groups recently achieved something that had never been done before. By implanting electrical devices directly on the spinal cord, they reversed some of the effects of the spinal cord injury and allowed people to independently walk again. So does this mark the end of the road in considering spinal cord injury as an incurable condition? Or is there still a long way to go before wheelchairs become a thing of the past? Researchers have been trying to use electrical stimulation to reverse the effects of spinal cord injuries for more than two decades . Artificially increasing electrical activity in the spinal cord helps to activate the nerves that transmit information between the limbs and the brain. While some nerves are permanently damaged by spinal co...
