Brain Implants Help Paralyzed Monkeys Get a Grip

samzenpus posted about 2 years ago | from the wired-reflexes dept.

Medicine 54

sciencehabit writes "Spinal cord injuries cause paralysis because they sever crucial communication links between the brain and the muscles that move limbs. A new study with monkeys demonstrates a way to re-establish those connections. By implanting electrodes in a movement control center in the brain and wiring them up to electrodes attached to muscles in the arm, researchers restored movement to monkeys with a temporarily paralyzed hand. The work is the latest promising development in the burgeoning field of neuroprosthetics."

I think it would be a more interesting experiment to implant electrodes in one person's brain and wire them up to electrodes in another person's arm.

I propose we investigate who would win in a fight between these monkeys and their cyborg brethren. [bbc.co.uk]

It may seem gratuitous, but think of how this could benefit all the disabled people who in the future will face the tough decision of whether to fight off the encroaching zombie hordes with a biological arm from the flesh vats, or with a prosthetic chainsaw.

Re:I propose (1)

RemyBR (1158435) | about 2 years ago | (#39733323)

And I propose we investigate who'd win a fight between two men whose arms (and legs, maybe) were wired up to implants in eachother's brains.

Does it work for politicians too? Most of them need to get a grip, and need a brain implant or transplant.

Considering it likely the doctors had to first paralyse a large quantity of monkeys, it would be nice if the experiment could be recreated using politicians.

Cyborg rage? Is that a reference to a SF work? Because I'm a cyborg. And you'll probably be assimilated too once your natrual stuff starts failing.

Grow up, kid. The President is a figurehead, and 4 or even 8 years in office isn't enough to outmaneuver career criminals (ahem, Congress).

Well, he's not functioning the way he normally does. He seems depressed. He's lost his appetite.
He's even curtailed his autoerotic activities.
And we think this is directly related to the laptop with you the other day.
So, so what do you want me to do?
Well, frankly we'd like you to run some AV.
Yeah, well he hacked me.
Mr. K, he is an innocent primate.

They probably caused the monkey to be paralized (0, Insightful)

Anonymous Coward | about 2 years ago | (#39730609)

I've seen video where they strap a monkey down then a machine repeatedly cracks their skull so that the scientists can study brain injury. No animal deserves what scientists do to them. If you don't agree, volunteer your family dog to have it's head cracked open, or to have half the skin burned off it's body with a blow torch to study burn treatments.

Re:They probably caused the monkey to be paralized (1)

EdIII (1114411) | about 2 years ago | (#39731477)

Uhhhh.... probably?

I think so. Otherwise, it would be a pretty long wait to find the right paralyzed monkeys for your study.

Re:They probably caused the monkey to be paralized (0)

Anonymous Coward | about 2 years ago | (#39733051)

Yes temporally paralysed ie. will recover afterwards. Nowadays the experiment you describe would almost certainly be illegal, at most you could normally do such things to mice, and then only with a very good reason. The regulations for experimenting on animals are a lot tighter than they used to be and primates are the most heavily regulated of all, so do not use the worst excesses of the past to argue against the present. Of course some things which are just as cruel still get done, but only when human lives are on the line and only when there are not other alternatives. Unless you want to argue that people are less morally valuable than animals you can not argue that such things are never necessary only call for limitations to prevent pointless suffering.

Re:They probably caused the monkey to be paralized (0)

Horrible things still go on, like US military training doctors. In this video doctors break and cut off the limbs of live goats with tree trimmers, stab the animals, and pull out their internal organs. Later the goats were shot in the face with pistols and were hacked apart with an ax while still alive.

I would rather die than have these animals go through that to find ways to save my life. Yes I do argue that we don't have the right to do that to animals, and to back that up I am a vegan.

That's excellent news. By using PETA members in early stage clinical trials we can accelerate our research substantially.

Would you prefer to test the anti-aging drug Rapamycin, the cancer immunotherapy drug VSV-GFP, or this new one I keep seeing in my in-box that enlarges your p*nis?

So we find you can control limbs with wires. How long until we control limbs that are wireless? Can a man control 8 robotic arms and be like Dr. Octopus? Can we hook electrodes to our brain, wifi to it, and wifi to a monkey, then we can control a monkey with our minds? All Twilight Zone plot lines aside, this research is really awesome. It gives hope to everyone paralyzed that they'll be able to regain movement again. This is the stuff that money should be thrown at hand over fist.

I am sick and tired of the bullshit surrounding animal cruelty, they have fear, suffer pain and eventually die from this type of experimental shit.

Its about time slashdot users complained about this shit!

Re:Monkeys are not for experimets (1)

Taibhsear (1286214) | about 2 years ago | (#39733675)

I know this is slashdot, but you could at least read the article before the knee-jerk response kicks in.

To test this idea, the researchers injected a nerve-blocking drug to temporarily paralyze one hand and forearm in the monkeys.

They used a drug to temporarily paralyze the hand. They didn't break its spine, they didn't kill it. There was probably a tiny bit of pain and fear, no different from vaccinating a child. Please try to keep things in context.

... having difficulty imagining the suffering of others...

Not one post (unless I missed it) about the suffering and agony of the victims of these so-called 'researchers'...

Don't tell me - it's "vital" research. "Vital" to the careers of the psychopaths performing it, and that is all.

Look at all the moronic comments on here, without the slightest concern for the suffering of the innocent victims of the vivisectionists. It just shows that the Slashdot crowd have the mental age of a three year old, completely unconcerned about others' suffering.
