Severed Optical Nerves Can Be Made To Grow Again

chrisd posted more than 12 years ago | from the well-will-you-look-at-that dept.

News 187

Anonymous Coward writes: "It is being hailed as one of the most significant advances in nerve regeneration in a decade. After severing an optic nerve in rats, neurologists have found a way to reconnect it to the brain so that it once again transmits normal electrical signals. As reported in the New Scientist this achievement is a first in mammals, and may hint at ways of reversing some types of blindness in people. Scientists also hope to use a version of the technique to treat people with spinal cord injuries.

What about other nerves? (3, Interesting)

It you can regenerate the optic nerve (or rather, prompt it to regenerate), what about other nerves? Spinal cord? Maybe you could make Rush Limbaugh hear again (or at least make him deaf only to the poor, human suffering and forward-thinking ideas like he was before).

Rush's ailment (0)

Anonymous Coward | more than 12 years ago | (#2667920)

why has it not been said that of all the senses Rush Limbaugh could have lost due to atrophy, hearing tops the list?

Or at least, "Recently, Rush Limbaugh lost one of his 5 senses...fortunately, it was only his hearing, so this should have little impact on his daily life."

Re:What about other nerves? (3, Interesting)

Master Of Ninja (521917) | more than 12 years ago | (#2668041)

Nerves are hard to regenerate once cut - the actual nerve cells only proliferate at birth, so if you lost a nerve cell that's them gone forever. (That's why there so much research into trying to get stem cells to differentiate in vitro - they can be used to replace these cells which cannot divide)

However, if you cut the axon of the cell (the bit which connects to other cells put very simply) it can regrow, but don't expect it to take the same function. The part of the axon which is cut off will die, and the cell should make new synapses. As I said these might not be of the same function.

The technique described could work for spinal axons, but there are a lot more of these than in the eye. So you would have to get each cell to connect to its exact axon in the first place and then stimulate them to reconnect. I would think it would be quite difficult to do the above.

Anyway after this the patient would have to learn to regain control of their body. Note how they said it only partially regenerates the nerve. You're still not going to get all sensation or motor control - the potential for damage to a person who undergoes this and cannot control themselves properly is massive. I can't see this working for a time, and then there will have to be years of trials (after persuading ethics committees that this is a good ides). I think they'll have to find a way of improving the technique first.

I have no clue who Rush Limbaugh is - is he metaphorically deaf? His deafness might not be due to damage to nervous tissue anyway, but could be due to damage to the actual ear.

(Some of the above is IMHO, and some of the facts may be wrong - or oversimplified - as science moves very fast; try searching biomedical databases for yourself to see how hard it is. Correct me if i've got anything wrong please)

Imagine having a mathematics co-processor, that solved every mathematical equation almost instantly, directly embedded into your brain. Even if only a few people chose to adopt these, the advances they could make for physics and math are staggering.


I know a lot of people would be uncomfortable with implanting technology into their bodies.. but, to me at least, the idea of a society in which information could be wirelessly transmitted in to your brain is beyond cool.

tuj (303347) | more than 12 years ago | (#2667891)

A very good friend of mine has a rare problem with the optic nerves in his eyes, which causes his vision to be so blurred that he is legally blind. All tests indicate that his eyes are shaped perfectly; he should have 20/20 vision. Furthermore, the doctors haven't been able to do much for him, since they dont' fully understand the problem. So they try to give him eye-glasses, and magnifiers, which don't do much good.

Research like this, when it might potentially spark a break-thru that could help someone close to you, is always great to see. I hope they make serious progress with this one.

Interesting, semi-on-topic Oliver Sacks tidbit (5, Interesting)

melquiades (314628) | more than 12 years ago | (#2667901)

I once heard Oliver Sacks talk about somebody who had been blind their whole life (due to completely opaque cataracts, I believe). A new surgery technique restored the fellow's sight. But when he woke up from surgery, all he could see was an overwhelming mass of incomprehensible color. He couldn't distinguish faces, object, or even simple shapes.

His eyes, it turned out, were functioning perfectly. But because he has been blind during infancy, the visual parts of his brain had never developed -- he had never learned to see.

He did slowly learn, but it was agonizing for him. His newfound sight was overwhelming and sent his brain into chaos. After a long time, with tremendous effort, he could shave for a minute or two in front of the mirror -- but it was absolutely exhausting, and had to finish with the lights off.

Eventually, an unrelated optical infection threatened to take his sight, and he chose to let it run its course. Returning to blindness was a tremendous relief.

Perhaps slightly off-topic, but fascinating!

Oliver Sacks rocks (5, Informative)

Reality Master 101 (179095) | more than 12 years ago | (#2667981)

If anyone has any interest in how the brain works and the insights one can gain by looking at what happens when the brain malfunctions, I can't recommend the Oliver Sacks [amazon.com] books highly enough. He's a neurologist who studies the brain and has a positive gift for writing about his subjects. Not to be touchy-feely, but he writes about them in a very sensitive way to where you don't feel like people are getting "exploited" for his own gain.

Other tales in his books to whet your appetite:

1) "The man who mistook his wife for a hat", which is the title of one of his books about a man who, otherwise normal, had problems with misconnecting objects to their identities,

2) A woman who could perceive things only on one side (say the left), but not on the other, even though her vision was perfect. When she ate, she would have to eat one side, then turn the plate, eat another half, etc. She was perfectly sane, but just had this wierd perceptual problem.

3) The man who could not make new memories, and lived the same moments over and over. He could remember everything up to an accident he had, but nothing further. Every day he would re-meet the same people. They have to keep mirrors away from him because it freaks him out because he looks too old for himself.

4) The "anthropologist" on mars, who is a pretty famous autistic teacher I think at Colorado. She has perfect image recall, but is entirely without emotions. She actually has her own book that she wrote about what it's like to be her, but I can't remember the name of it (anyone?).

The books are absolutely chock-full of stories like this. If this stuff fascinates you like it does me, I give these books my absolute highest recommendation.

Re:Oliver Sacks rocks (4, Informative)

Reality Master 101 (179095) | more than 12 years ago | (#2668024)

Here we go: The book about the autistic teacher is called Thinking in Pictures" [amazon.com] by Temple Grandin. I've read this book, too and it's incredibly fascinating. The title reminds me of how her brain works. She literally thinks in pictures, and has to "translate" the pictures into words through a methodical process that she had to learn by rote.

Crystallins or Immune Sys? (4, Interesting)

krmt (91422) | more than 12 years ago | (#2667971)

I thought the idea that it was immune system stimulating growth pretty interesting. The immune system releases a lot of signaling molecules at all stages. I'm not an immunologist per se, but I've never heard of any of them stimulating growth, but that certainly doesn't rule out the idea.

The article said that it was just inflammation that induced growth. I somehow doubt that, since everyone who's ever had irritated eyes has felt the fun of histamines and the primary immune response in action. If that sort of thing could make the blind see again, I'd be really surprised, even if it is on a larger scale.

If it is the immune system, I'd bet on cytokines released by helper T cells (those things that HIV targets) simply because these cells release a ton of stimulants. This may be triggered by the nonspecific inflammation like the author suggested, but I'd bet on the helper T as actually secreting growth signal.

If it is possible to use the immune system to regrow neurons, it's very likely applicable in other parts of the body too.

Squiggy - The Hands Of Time

The once steel towers of this land have gone and rusted away
The one strong ethics of the worker have been sold away
The dollar equals slavery, a master to which we're loyal
A civil war over greed on American soil

Wooaaaah another factory closes
Woooooah Nobody gives a fuck
Woooooah They sold our dreams away
Woooaaah Turn back the hands of time

America for us really means America for them
A nation full of traitors, on which we can't depend
Our once shining streets are being turned into a ghetto
The ball of destruction has been rolling since the get-go

Wooaaaah another factory closes
Woooooah Nobody gives a fuck
Woooooah They sold our dreams away
Woooaaah Turn back the hands of time

The rich and powerful take more as the day passes
While the blind and hopeless sit back on their asses
But I won't be another number, I won't be another dollar, I won't be another
scapegoat in the corperate scheme

We're gunna beat beat beat 'em down
We're gunna beat beat beat 'em down
We're gunna beat beat beat 'em down
We're gunna turn this place around

Wooaaaah another factory closes
Woooooah Nobody gives a fuck
Woooooah They sold our dreams away
Woooaaah Turn back the hands of time

Wow, I am partially sighted and this innovation won't be able to help me or the millions of others affected.

It appears to be a lot of money and intelligent thinking thrown at the problem, instead of solving the cause (again).

Maybe we can give the electric squid RC car we saw earlier on slashdot human eyes, I could certainly use a replacement, and i AM very clumsy ;)

...everytime I hear something from New Scientist I can't help thinking about this article [theonion.com] . Its often interesting to read, but the results are not from an accountable source - always from some scientists somewhere that have questionable results...

All of the big breakthroughs that are real seem to be reported by actual news institutions.

Its just another straw on the coffin (another nail in the camel's back).

fix the optic nerve by a good poke in the eye (3, Funny)

"Finally they punctured the lenses in the rats' eyes which releases proteins called crystallins."



Well, we could repair your optic nerve miss, but it will involve crushing the lens of your eye. You'll be able to see again, but everything will look like it does in a circus mirror.

High School (1)

Renraku (518261) | more than 12 years ago | (#2668132)

I debated until I was blue in the face in high school biology classes that nerve tissue can regenerate if given the right materials and circumstances. Unfortunately, they were too closed minded to realize that regrowing nerve tissue isn't really that hard.

Re:High School (1)

Master Of Ninja (521917) | more than 12 years ago | (#2668181)

I don't think regrowing nerve tissue is that hard (as long as the original cell body of the nerve is still intect). It's making the nerve grow so that it regains its previous function which is the hard part.

I'm legaly blind in one eye, I have almost no depth preception. You know all of those 3d monitors that people keep on getting excited over? Well if Science keeps up its march I may be able to use them one day!! YAAAHHOOOOO!!!!

This will be great when they can apply this to different nerves. John Bobbitt my get himself back to normal after all.

Not applicable to humans (1, Informative)

Anonymous Coward | more than 12 years ago | (#2668202)

The so-called "animal model," such as that used in the experiment described, has received increasing criticism in recent years. A number of scientists have gone so far as to state that animal research for human health is categorically invalid. There exist several physician groups which oppose all animal experiments, for reasons of scientific invalidity alone:

incomplete result -- no info on sight restoration (2)

tim_maroney (239442) | more than 12 years ago | (#2668257)

The story does not say anything about sight having been regained through use of the technique, only about the degree of regrowth. If any tests on sight were done, they are not mentioned. That makes this result highly questionable in terms of possible clinical value.

There are many things that could thwart the restoration of sight -- for instance, if severed axons joined to the wrong partners, then sight could be kaleidoscoped; or if the axons grew back incorrectly, they might not transmit action potentials reliably.

Given that the lens is damaged in this procedure, it might not have been possible for them to test sight, but assuming there are other possible sources of crystallins, a followup experiment that tests for sight restoration should be this team's first priority. I'll go out on a limb and predict that 30% regrowth plus probable kaleidoscoping will prove to be only barely useful.

I have to wonder... (5, Interesting)

Alioth (221270) | more than 12 years ago | (#2668268)

One thing I have to wonder about is if the nerves grow up the 'wrong' pathway, and how long it will take the brain to sort it out.

When I was 15 years old, I put my hand through an old glass door while trying to open it. The glass sliced through my right wrist, severing pretty much everything (apart from about half of one tendon). I probably don't have to mention the large quantities of blood that went everywhere.

Six hours of microsurgery, and it was put back together again...followed by three months of three hours a day physiotherapy.

The thing I found fascinating was that when the median nerve [0] (the nerve that runs up the middle of your wrist and supplies your index finger to thumb and half your palm) is that some of the nerves went the wrong way. I could stroke part of one finger, and the sensation would come out somewhere else - like a different finger, or a different side of the finger. It was...well...very weird.

However, it didn't take long for the brain to fix it. After a short while, the brain learned the error, and sensations came out in the expected place.

It's one thing when this happens to fingers - but I wonder if you'd need some kind of "optotherapy" to coach the brain to fix the image problems you'd get with optical connections wired differently to how they were before.

[0] Movement of the fingers is controlled by the muscles in the forearm. The median nerve does sensation.
