Robotic Arm Controlled By Monkey Thoughts
mallumax writes "The BBC reports that Pittsburgh University scientists have succeeded in creating a robotic arm, controlled by probes inserted into the brain of monkeys. The probes interpret signals from individual nerve cells in the motor cortex. Monkeys were able to grasp and hold food with the robotic arm. Since the number of nerve signals for even small movements is huge the scientists used an averaging algorithm to obtain the movement signals."
That's my monkey controlled robot arm's hand on your ass.
Wouldn't this also be a sign that monkeys are capable of fairly sophisticated tool use?
"The inventors believe it could help people who have lost limb function through disease or trauma." Why are all these types of enhancements framed in terms of the disabled? We are disabled. Why must we hunger, breath air, thirst, sleep? I wonder if these researchers are just giving the public this. Can they see the obvious leap to transhumanism?

Could tissue growth be suppressed locally, maybe by having a supply of some anti-growth factor dispensed from the (possibly porous) probes? It would still have to be replenished; but undesirable side effects (suppressing tissue growth elsewhere) could be eliminated or mitigated and the probes could last much longer.

I'd be more concerned about the algorithm they use. Due to the large amount of messages, most are scrapped and only the seemingly 'important' ones are saved. I'd want to make sure that the algorithm is actually effective before trying out this technology, or I'd like an explaination as to how they sort unimportant signals from important ones. Otherwise, the movements of the tool may not relate to what the user actually intended.
I'm not stressed. I'm just terribly, terribly alert.

The article says the team's biggest problem is that after about 6 months tissue grown begins to interfere with transmission of signals to the probe.

This work is *OLD*. Take a look at the Boston Arm for examples of why it doesn't work well. The electrodes cannot yet be permanently linked to small enough numbers of neurons to prevent huge amounts of signal noise, and you get a minimum of half a second of phase delay in the control systems to average out the noise. And the smaller you make the electrodes, the higher the impedance of the electrode, which also reduces your available signal level and potentially lowers your signal/noise.
Mechanical arms reading motion of other moscles still works a lot faster than any of the neural implants. Look at David Edell's work at MIT for examples of potentially useful electrode technologies, involving electroplated slots in semiconductor grade silicon.
I don't know about you, but I'd rather have a monkey arm controlled by robot thoughts.
According to a Popular Science article on the subject, several humans have already undergone similar treatments, allowing them to control a computer mouse by thought. In addition, scientists were able to use a weak FM transmitter to circumvent uncomfortable wiring.
Maybe with a "lossy" algorithm like this that wouldn't be as big a factor... then again, maybe the answer is making the elctrode/brain/skull part more durable.

yeah it just happens to be completely coincendental that the monkey managed to pick up the food with teh arm and eat it. The odds of that happening by coincedent are astronomical!
Plus, the brain adapts itself so that it can use the arm, there is no reason to completely adapt the interface to the brain.

You beat me to posting that link.
I just want to say that the case mentioned by the parent posting will probably be the first time in legal history that anyone pleads innoncen on the grounds that, 'The monkey made me do it'.
HA! I just wasted some of your bandwidth with a frivolous sig!
I'm guessing the first use of that arm was to fling a whole lot of feces.
First off, it's the University of Pittsburgh, not Pittsburgh University.
The actual web site for Schwartz's lab:
http://motorlab.neurobio.pitt.edu/
The above link has neat videos of the monkey moving the arm around.
Researchers like Schwartz who record from motor areas of the brain do cool stuff, but I'm personally more interested in folks like the Andersen Lab who do recording from more goal-oriented areas. Basically, it's a difference between a command to "move my elbow this much" versus "I want to grab this object."
Here's a PDF link to a paper published by Schwartz and others in 2002. Here's the abstract:
Direct Cortical Control of 3D Neuroprosthetic Devices
Dawn M. Taylor, Stephen I. Helms Tillery, Andrew B. Schwartz
Three-dimensional (3D) movement of neuroprosthetic devices can be controlled by the activity of cortical neurons when appropriate algorithms are used to decode intended movement in real time. Previous studies assumed that neurons maintain fixed tuning properties, and the studies used subjects who were unaware of the movements predicted by their recorded units. In this study, subjects had real-time visual feedback of their brain-controlled trajectories. Cell tuning properties changed when used for brain-controlled movements. By using control algorithms that track these changes, subjects made long sequences of 3D movements using far fewer cortical units than expected. Daily practice improved movement accuracy and the directional tuning of these units.
It doesn't matter because the brain adapts to losing information like that and tries to send the data differently so that it can manipulate the arm the way it wants.
He is more machine than monkey now, twisted and evil.
Why does it matter? All they care about it moving the arm in that case. It's not that the "filtered" signals are being blocked from the body, and just getting lost. The article states that the monkey tried using his regular arms for a while until he realized that the new arm worked when he tried as well.
But, while I'm sure that if any harm came to the monkey in the end that animal rights groups would be all over them, I'd like to hear about follow up once the monkey was disconnected from the machine. Do his arms work normally? I doubt the probes have any lasting damage, since they are pretty small and don't penetrate the brain enough to destroy parts of the brain. Think of them as more... fitting "between" the cells, though I'm sure this analogy doesn't do it justice, and is not technically accurate.
I for one welcome our robotic simian poo flinging overlords.

That doesn't seem like such a big problem. I mean, if you are missing an arm and they could give you a brain-controlled robotic one to replace it, wouldn't you be willing to go for it? (Assuming of course, that this had been thoroughly researched and proven to be safe, first.)
No, the animal rights groups don't care if or how much the animals suffer, they just don't want them being used in research, period. They're in no more danger of being firebombed if the monkey gets hurt or even killed than if the monkey is just fine.

If you cant sleep, your life will be a nightmare.
If you're never hungry, you'll forgot to eat and eventually die.
If you're never thirsty, you'll not drink, and die in a few days or weeks.
If you never breath, you'll die pretty quick.
I read about this in scientific american over a year ago??
Hunger--we already have intravenous food (such as Resource).
Breath air--our breathing system is quite inefficient. Heart-lung machines are already available. We'd be "breathing", but we wouldn't be conscious of it.
Thirst--See hunger.
Sleep--This is more interesting. Certain drugs keep you up for days. A designed sentience may or may not need sleep.

Monkey-controlled robots kill people.
I was watching the Discovery channel awhile ago (probably close to a year, if not more) and saw something that may have related to this research. The scientists began by giving the monkeys a joystick (or mouse, memory is hazy) and when the monkeys moved the cursor to a box on the screen they would receive a treat. Then they took away the control and wired the monkey's brain so that (s)he could simply use thought to control the cursor on the screen. Apparently this was done by thinking of the same movements that the monkey would do to maneuver the cursor but not actually physically performing the action. I'm kind of curious if this current robotic arm is an extention (no pun intended) of that research or completely unrelated.
Finally! We can get an infinite number of monkeys in an infinitely large room with an infinite number of typewriters and have all the works of Shakespeare produced. [*]

Welcome our bionic monkey overlords
What I'm wondering is about the drain that such a system would place on your mind. In order to receive the signals, these probes are taking...electricity (excuse my ignorance)...from the brain without, I assume, replacing it. Will this have a negligible effect on the day to day running of the brain or will it be significant enough to show a drop in intelligence through tests?
1) Plug the probe onto your brain
2) try to pat your head with your right hand, rub your belly with your left hand, and scratch your neck with the robotic arm.

You're kidding, right? The Boston Arm was *EMG controlled*, not electrode controlled. EMGs have poor resolution.
Of course, old data-out electrode-based BMIs (Brain-Machine Interfaces) weren't great. They got coated with organic material. They tended to tear up the neurons that they were probing. Etc. Modern BMIs, however, are rather different - often over a hundred blunt teflon-coated probes in a single array. With these, you get a 70% prediction rate on things like arm movement with 100 neurons, and 95% or so with 500-700 neurons.
As for latency, just a quick search reveals one number: Duke's arm from 2003 had 60-90ms delay. Not "instantaneous", but not bad either. And the numbers are really getting better.
As for how "old" this tech is, it wasn't until the 90s before it was shown for certain that specific motor control activities are greatly distributed, making BMIs feasible; there was a popsci article a while back that discussed the discovery.
"Well, then fire it up and show me what this..." (sigh)
Now, The monkey just needs to think about spanking itself.... Neato.

This is pretty ghoulish and a bit disturbing, even though there is every indication that this kind of stuff probably happens every day.
It got me thinking, why are we doing this? Why is it alright to saw the skull off an ape but not a human? As far as I can tell this question can be answered in three ways.
The first answer is that there is some huge insurmountable difference in kind between apes and humans, which makes it alright to subject apes to torture for the purpose of research, but not humans. This is basically the religious argument, because so far nobody has succeeded in providing a measure of this difference, much less in quantifying it. Meanwhile all the differences which can be measured, such as genetic difference, seem to point overwhelmingly in the other direction, namely that the difference is small and quite surmountable. Note that all the answers of the form "apes don't really suffer" or "it would violate the integrity of the human" and "it is against the law" all belong in this class.
The second answer tries to qualify the conditions under which it is alright to saw a monkey's skull off. We know the apes suffer, we may try to minimize their suffering, but ultimately we judge that the benefits from research warrant whatever suffering we subject the monkeys to. But there are two huge problems with this answer. First, if the research is really so important, then why don't we sacrifice a few humans instead? We can answer this question qualitatively by saying that there is a fundamental qualitative difference between humans and monkeys (which brings us very close to the first answer), or we can answer this question quantitively by saying that although monkeys and humans are both part of the same continuum, monkeys are simply worth less than humans, since they lack the mental acuity or dexterity of humans, or some such. But if mental acuity or dexterity are the criteria, then why not use retarded or disabled humans? Second, who determines the value of the research and on what grounds? And does this mean that some research might turn out to be so vital that it requires human guinea pigs?
Finally the third answer just posits that it's alright because we can. This is the position that might makes right. This is the most logically consistent position, even though it is ethically bankrupt (since all ethics are the ethics of the weak -- the strong need no ethics).
While none of these answers is entirely satisfying, generally the second answer seems to be the most palatable as well as the most common, since at least it tries to address what many people feel are legitimate issues. The catch is that it enshrines often questionable research on the backs and skulls of living, breathing monkeys. Although research for the sake of research has frequently enhanced our lives in unexpected ways, it has also frequently been a dead end. And while modern medical science can pull some amazing rabbits out of its high tech hat, the significance of these accomplishments can sometimes seem shallow when compared to that of mundane technology such as penicillin, antibacterial soap, and tap water.
I just hope this isn't another oversold "breakthrough" which turns out to have little practical use other than to funnel more funds into the departmental cash register.
I have several co-workers who operate their entire bodies with monkey thoughts....
Essentially the same thing was reported in the October 2002 issue of Scientific American. Time picked up on it the following year, as schmobag pointed out earlier.
This is certainly an admirable refinement of the experiment, but it is certainly not exactly new, either. It's a better robotic arm, a different monkey, and a different university (the original experiment was at Duke University, this one's at U. of Pittsburgh), but monkey robot arms are not a new phenomenon at all.

They are not quite taking electricity in the manner you think of. For one, when a neuron fires it generates an electric field by pumping ions out of its cell body, creating a voltage. Tapping this would only reduce the voltage of that one neuron (although if done too much, it might prevent the activation of the next one in the chain). The connection between that one and the next neuron is chemical, however, so you're only draining power from one neuron.
Secondly, there exist a number of electrical components that can amplify a voltage signal without drawing any power from the source. A mosfet, for instance, can easily give you an amplification of 5-10x while drawing almost no current from the source. This means you could put your probe next to a nerve and measure the signal with only a negligible influence on the signal itself.
Jw
I believe that one of the problems with this is that you cannot read the signal from individual neurons, but only from large regions of the brain. This would be nowhere near exact enough to control the motion of fingers, for example.
Jw
What were they thinking? Now, instead of just fighting Terminators or warrior monkeys, they are going to team up against us. We're DOOMED!!!!
