Single Neuron Wired To Muscle Un-Paralyzes Monkeys
GalaticGrub writes "A pair of paralyzed monkeys regained the ability to move their arms after researchers wired individual neurons to the monkeys' arm muscles. A team of researchers at the University of Washington temporarily paralyzed each monkey's arm, then rerouted brain signals from a single neuron in the motor cortex around the blocked nerve pathway via a computer. When the neuron fired above a certain rate, the computer translated the signal into a jolt of electricity to the arm muscle, causing it to contract. The monkeys practiced moving their arms by playing a video game."
Who's the grad student who had to break those monkeys spines?
Give me Classic Slashdot or give me death!
But can you teach them to type??

"Monkeys learn to play video games." I actually think that's more amazing.

It was the best of times, it was the blurst of times. Blurst of times! Stupid monkey!
Let us not become the evil that we deplore.
Amazing! This is truly a wonderful time to be a monkey.

Certainly they may be jumping for joy. Though there is more to it than just wiring an electrode to a muscle before the fat lady can sing again.
A functional limb without any sense of its location in relation to the body is a problem, one without feeling is also a problem. Did they think about electrodes for everything else the nervous system is responsible for too?
The researchers who published this should have 'Correlation is not causation' written in giant billboards in front of their houses.
Just 2 monkeys regained movement after the experiment does not mean that rerouting brain signals past blocked nerve pathways using a single neuron controlled by a computer did anything at all. They should have waited until they had ruled out other possibilities, like divine intervention, before publishing results. For shame!
Seems ripe for exploitation...

Can a human control a monkey arm?
If so, can we control its entire body?
If so, can we do it remotely, through a wire to a cell phone.
If so, how long until someone decides to use monkeys as freedom fighters?
Yes, science should never go down this path, but hey, it is still possible to look down the paths
God spoke to me.
Whoever tagged this article "shockthemonkey" is awesome.
Odd note, but monkeys seem to have a preference for holding down the s key on american keyboard layouts.
Everything will be taken away from you.
They have their specialization and you have yours.

As opposed to the mechanical prosthetics that feed information back?
Now we can reuse stuff that's already built in.
It's certainly true that proprioception (the ability to sense joint location) and sensation of muscle tension are useful feedback systems in coordinating limb movements. It's well known in the field (I'm a neuroscientist), however, that several neurological conditions rob patients of these sensations and they're still able to move their limbs effectively (though not perfectly). I'd guess that a patient who was paralyzed wouldn't mind being able to move their arms again, even if they couldn't feel where they were without looking.
Am I the only one who's more interested in the medical significance of this, instead of the silly aspect of monkey-gaming? Holy crap guys, use your brains.
This means that we have the potential to repair neural damage, potentially severe damage as well!
I see particular use with pacemakers. Rather than just pulse the heart at a given frequency, read what the brain wants the heart to do, and do that! You could do the same thing for the lungs as well, although I'm not sure how often someone who damages that nerve makes it to the hospital in time.
Other use could be with amputation victims. Helping restore function to reattached appendages/digits, or controlling prosthesis...
I wonder if, further down the line, it would be possible to do this to sensory nerves as well, not just motor control/response...

That site is real, isn't it? For the first few minutes of reading I convinced myself that it was just a funny hoax site, but the deeper I went into it the more scared I became...
Would it be irony if I prayed to God to free us from religion? I still don't have that whole irony thing down yet.

Apparently, grad students will write a thesis about anything...
I wouldn't be too sure. This is just the latest in a long string of research findings that point toward an astounding degree of neural plasticity in adults. At this point, if I had to guess, I'd say that wiring one sensory nerve from the general area back to a single neuron would end up restoring a noticeable degree of "feeling".
'Cause you know, neurons that fire together wire together.
