While humans are able to regenerate some organs, such as the liver, spinal tissue, more specifically, the nerve cells that connect to our brain cannot. Paralysis usually occurs when those nerve cells get damage and are unable to transmit signals to the brain. Fast forward to today, researchers have used electrode implants (inserted along the spinal cord) to help four men with below-waist paralysis for more than two years, regain movement in their legs.

According to Dvice, “By implanting electrodes along the men�s spinal cords, they were able to reawaken nerves via electric stimulation. Afterwards, the men could flex their main joints (including toes, ankles, knees). This ability has only grown by combining physical therapy with electrode implants.”
