And then ideally you then also want to plug in the retina.

That's got to be one of the most complex things to possibly.

But Alex, tell us a bit more then about this new procedure, about how they managed to actually keep the retinas alive.

You mentioned that the retina is really sensitive to oxygen levels and that's kind of critical here, isn't it?

It gives you 10 hours to do that incredibly complicated transplant you just tried to imagine.

So that brings us really nicely to the other story we want to talk about today, which is the restoration of a severed spinal cord.

And the initial aim of this kind of research is to treat spinal cord injuries, which can leave people unable to use their limbs.

And there are more than 15 million people living with spinal cord injury.

So a way to restore this would be brilliant.

Yeah, and we'll get to that in a minute.

Alex, the neurosurgery in this particular study concerns fixing the spinal cords in pigs who've had their spinal cords severed.

And so what they essentially did is they fixed this injury that was inflicted on them and these pigs were able to walk again.

It's gruesome, but quite amazing.

So that implies then that there is some kind of electrical conduction going across this wound.

Yeah.

So it sounds like you've got PEG, which is kind of a gel, isn't it?

And chitosan, it's like a structural polymer.

So this is like a clever kind of a glue to bring the severed bits together.

And then what, the electrical stimulation then is trying to get it all sort of...

working together again?
