restoring eyesight in brain injury - the future
Just read this article in the bbc news section, I’ve given an excerpt of it below, a link to the full story can be seen at the bottom of the page. It looks like a great through.
Nanotechnology has restored the sight of blind rodents, a new study shows. Â
Scientists mimicked the effect of a traumatic brain injury by severing the optical nerve tract in hamsters, causing the animals to lose vision.
After injecting the hamsters with a solution containing nanoparticles, the nerves re-grew and sight returned.
Writing in the Proceedings of the National Academy of Sciences, the team hopes this technique could be used in future reconstructive brain surgery.
I’ll be sure to read the full article in PNAS and give you a good overview of it, until then it can be found at the bbc site.
