Dr. Woerly, in his laboratory in Canada, tried  his product on animals: rats and latter on cats. These latter having undergone a complete lesion were grafted with Neurogel. Cats, after several months of rehabilitation on a treadmill, regained the mobility of their limbs. After euthanasia, the Neurogels which had been grafted several months earlier, were removed and cut into transverse strips to be analyzed. The gel strips showed clearly the passage of the neurons throughout the length of the channels.
