Paralyzed Patients Walk and Swim Again After Receiving a Spinal Cord Implant
The spine is critical to human mobility. The spinal cord connects the brain to the branches of the nervous system throughout the body. To move the legs, for example, a signal is sent by the brain's motor cortex through the spinal cord to the muscles of the legs. When the spine is severed, this communication becomes impossible, resulting in paralysis.
