Some of the IRP researchers have worked over the past 5 years to a project which seem ambitious, namely to restore nerve connections inside a damaged spine. As you can see from the movie the results are impressive: thanks to a chemical solution injected into the affected area, stimulating electrodes and a harness robotic guinea pig has developed new connections which would put the two separate sections of the spine until then interrupted.
After only a few hours after injection, the cells receive a shock from the electrodes by helping damaged nerves responsible for movement control. The robotic interface that keeps the harness he did the rest, helping the mice to walk independently, without forcing the pace and remarkable progress, as witnessed by the project manager Grégoire Courtine:
Our rats have become athletes when just weeks before they were completely paralyzed
