"During the GEMINI procedure, the surgeons will cut the cooled spinal cords with an ultra-sharp blade: This is of course totally different from what happens in clinical spinal cord injury, where gross damage and scarring hinder regeneration. It is this "clean cut" the key to spinal cord fusion, in that it allows proximally severed axons to be "fused" with their distal counterparts. This fusion exploits so-called fusogens/sealants."
