Brain-to-brain network allows three people to share their thoughts
There have been experiments in direct brain-to-brain communication before, but that's now extending to full-fledged networks. Researchers have developed a three-person brain network that lets participants send thoughts to each other -- in this case, to play a Tetris-style game. It used familiar technology, but in a much more scalable format.
Fluctuating brain networks help you handle complex tasks
Researchers already know that the human brain isn't static, but it's now clear just how dynamic the mind can be. A Stanford University team has discovered that the networking between brain regions will fluctuate depending on the complexity of tasks. If you're at rest, your brain's components are relatively isolated. Handle a complicated activity, however, and the level of networking ramps up. The more interconnected your brain is, the better your performance -- in a memory test, those with the most integrated brains were the quickest and most accurate.
Yes, this is dog: No More Woof aims to translate canine thoughts into human speech
Head over to Indiegogo today and you'll find a particularly wacky (and risky) project bidding for your investment. It's a device that goes by the name of No More Woof, which admittedly sounds like it does horrible things to dogs' vocal cords, but which actually promises something very different. It's a canine-sized headset that consists of EEG recorders connected to a small Raspberry Pi computer and a loudspeaker, supposedly allowing "ionic current flows" in a dog's brain to be translated into human speech. A $65 model is said to distinguish between three different thoughts, including tiredness and curiosity, while more expensive options will have more sensors and more powerful software. The only hold-up (and it's a big one) is that this project is being offered for crowdfunding while still at the concept stage, and all investment will be kept even if the funding target isn't met. According to a disclaimer on the Indiegogo page: "Yes, we HAVE achieved some results, but we are very far from a mass-producable product. That said, we believe that within a few years the technologies we are working with will revolutionize our relation to pets and animals." Indeed, there's no evidence that ST, the Scandinavian research lab behind No More Woof and last year's equally strange iRock rocking chair, has managed to come up with anything like a working prototype -- or at least there's no sign of one in the long-but-vacant video embedded below. Nevertheless, if dog barks are eventually mistranslated by this sort of "novelty science" (a word ST actually uses to describe its own research), who'll be any the wiser?
IBM says mind control next big thing in human-computer interaction; GLaDOS offers cake reward
From the ongoing Google-Apple turf war on voice recognition to Microsoft's gesture tracking with Kinect, humans continue to push the envelope on how to interact with computers and devices. Now IBM says mind control will be the next field to see a big leap, predicting breakthroughs within the next five years. Keep in mind that they're not talking about controlling humans a la Gorilla Grodd ... yet. Instead, they're talking about controlling computer actions and devices via brain waves. IBM software guru and potential Borg recruit Kevin Brown (pictured right) has already been using a headset to move cubes on a computer screen at will. Given the ongoing progress with mind-controlled cars and BrainGate, IBM's prediction might not be too far-fetched.
The Thinking Machines flashes back to 1968 for a lesson in computer logic, sideburns (video)
Another dusty gem's emerged from the vintage gold mine that is AT&T's Tech Channel archive, and this one's packed full of useful information and some classic Jetsons-style animation. The Thinking Machines pits man against computer to explain how the things reason, and it does so with a soundtrack that's straight out of, well, 1968. Unsurprisingly, the film's populated by giant, button-laden switchboards, early computer graphics, ladies sporting beehives, and gents rocking unfortunate facial hair, but if that doesn't do it for you, it also offers genuine pearls like this: "Best of all, they never get bored. Like other machines, they can do the same monotonous chores all day long without complaining." Someone should tell that to the disgruntled Roomba residing in our hall closet. Check out the full video in all its dated glory after the break.
BrainGate hits 1,000 day mind-control milestone, nearly three years of pointing and clicking
Aspiring Svengalis rejoice! For BrainGate has reached a significant landmark in computational thought-control -- the 4 x 4-mm implantable chip has given a woman with tetraplegia the ability to point and click with her brain for 1,000 days. An article recently published in the Journal of Neural Engineering said the woman, known simply as S3, performed two easy tasks every 24 hours, using her mind to manipulate a cursor with 90 percent accuracy. Each day she was monitored, S3 would post up in front of a computer and continuously command the thing with her thoughts for 10 minutes. Functionality reportedly deteriorated over time, but the paper points to the chip's durability, not sensor-brain incompatibility, as the culprit. Research is currently underway to incorporate BrainGate into advanced prosthetics that could get tetraplegics like S3 up and moving again. Now, how's that for the power of positive thinking?
UCLA / Caltech researchers help patients move mouse cursors with their brains
It's certainly not a revolutionary new concept -- whiz kids have been tinkering with brain-controlled interfaces for years on end -- but a collaboration between UCLA scientists and colleagues from the California Institute of Technology has taken the idea one leap closer to commercialization. Itzhak Fried, a professor of neurosurgery at UCLA, kept a close watch (via embedded electrodes) on how a dozen humans reacted to certain images, and eventually, Fried and co. were able to show that Earthlings can "regulate the activity of their neurons to intentionally alter the outcome of stimulation." In other words, they were able to move a mouse cursor with just their mind, and brighten a test image with a 70 percent success rate. By honing the process of controlling what actions occur when focused on a given subject (or input peripheral), it opens up the possibility for paralyzed individuals to not only check their email, but also control prosthetic limbs. It's hard to say when this stuff will be put to good use outside of a hospital, but the video after the break definitely makes us long for "sooner" rather than "later."
DARPA seeks out remote controls for soldiers' minds
DARPA is always on the lookout for the newest, zaniest gadgets but this time, we think it's gone too far. According to the Department of Defense's recent blog post, the military is interested in developing remote control techniques using ultrasound... for soldiers. Arizona State University neuroscientist William Tyler has been working on the project for several years, and now, DARPA is getting involved as well. Tyler and his team have developed a transcranial pulsed ultrasound capable of stimulating brain circuits from outside of the brain, and it can target deeper parts of the brain than past devices. The prototypes are small enough to be placed inside of a helmet, and the plan is to improve its spatial resolution with DARPA's new infusion of funding. We know they're probably looking to do cool stuff like make soldiers think they're nice and cool when they're actually frying in the sun, but we can't help but get the creeps from this one.
"Thought helmets" could enable voiceless troop communication
This won't mark the first time the US government has looked into other means for helping soldiers communicate on the battlefield, but it's one of the first instances where vocal cords aren't even necessary. The US Army has recently awarded a $4 million contract to a coalition of scientists, all of which will soon start developing a "thought helmet" to enable voiceless, secure communication between comrades. In theory, at least, the helmet will boast a litany of sensors that will hopefully "lead to direct mental control of military systems by thought alone." According to Dr. Elmar Schmoozer, the Army neuroscience overseeing the program, the system will be like "radio without a microphone." Oh, and don't think for a second that they aren't considering civilian applications as well -- passing along jokes on the boss via telekinesis? Yes, please.[Via Slashdot]
New bionic limbs to be controlled via brain-mounted sensors
Researchers at Osaka University are redefining "thought-controlled" limbs. Hailed as the first endeavor to dabble in the world of bionic phalanges by requiring open-skull surgery, the research is seeking to develop "real-time mind-controlled robotic limbs for the disabled." Of course, it's not the goal that's striking, but the means. Essentially, gurus working on the project are hoping to place electrode sheets directly on the surface of the brain in order to "obtain a more accurate signal," and amazingly enough, they're currently working to sign up willing subjects that are already scheduled to have brain electrodes added to deal with "monitoring epilepsy or other conditions." Maybe the bionic beings really aren't that far off, eh?[Via Pink Tentacle]
Researcher claims to read thoughts from neuronal activity
Mind reading developments seem to pop up every so often, but this particular case is somewhat extraordinary. How so? Probably because a University of Leicester researcher has outright proclaimed that his team "can read human thoughts from neuronal activity." Reportedly, Dr. Rodrigo Quian Quiroga and colleagues were able to optimize a decoding algorithm and use it to "infer the stimulus from the neuronal firing," and during tests in which patients were presented with a vast database of images, the team was seemingly able to "predict what picture the subject was seeing far above chance." Beyond giving sci-fi drama creators a bit more to work with, the technology could also be used to transmit thoughts to bionic appendages in order for paralyzed individuals to better care for themselves. Still, there's quite a few ethical / clinical issues that would have to be worked out before this stuff ventured beyond the lab, but we definitely can't argue with the premise.[Via Physorg, image courtesy of University of Leicester]
Brain2Robot project creates EEG-controlled robot arm
Thought-controlled appendages are far from new, but an international team of researchers have apparently created an apparatus that aims to make the lives of paralyzed individuals a tad easier. The Brain2Robot project utilizes electroencephalograph (EEG) signals in order to give patients the ability to control a robotic arm, which could eventually be used to do everything from hold periodicals to lift a cup of coffee. Reportedly, the arm could be ready for commercial use within just a few years, but there's no mention of an expected price range. Granted, we'd be a bit more excited about all of this if the technology were somehow made mobile, but it's hard to kvetch about a helping hand, regardless.[Via Primidi]
