Restored in mice and will soon be tested on humans

Recently, a group of scientists from the Lausanne Federal Polytechnic Institute (EPFL), Switzerland, announced the successful test of the restoration of spinal cord injury in a spinal cord injury by a project named NEUWalk.

>>> Race cars for people with paralysis

The team of scientists tested mice that had their spinal cord cut in the middle of their back, which caused the signals that control the limbs sent from the brain to be completely disabled. At the broken spinal cord, scientists implanted flexible electrodes. Their task is to transmit electric currents that stimulate the broken spinal cord, replacing the signal transmitted from the brain.

Gregoire Courtine, a neuroscientist, and head of the study, said: "We have completely controlled the two limbs of the mouse. It cannot control its limbs by itself after it has broken the spinal cord. I can stimulate and re-activate the broken spinal cord so that it can walk naturally. We have controlled the step and how to lift their legs. "

Co-author of the project, neuroscience engineer, Silvestro Micera also said: "The successful discovery of how the nervous system will be effectively exploited into the development of artificial neurological technology. I believe it will significantly improve people's lives when faced with neurological disorders ".

It is known that in the summer of next year, June 2015, scientists will test clinically on humans. They plan to test patients with spinal cord injuries. This work will be carried out at the Glat Platform laboratory located on the campus of the University Hospital of Lausanne, Switzerland. The laboratory consisted of a treadmill and a ground-based support system, 14 infrared cameras that recorded reflections on the body and two cameras recording the patient's movements.
