Mattel's Mindflex coming October 1st for $99.99

by Darren Murph, posted May 24th 2009 at 12:57AM

It's not often that a Mattel toy targets the 18 - 128 demographic, but we'll be frank -- the Mindflex has us all sorts of intrigued. Originally introduced at this year's CES, said game is a brain-powered fun-fest that relies on intense mental activity to control the height of a ball suspended in a column of air. Early on, we heard that it would land sometime during this year for $80, but it seems as if only one of those factoids will prove true. Indeed, Amazon has it listed to ship on October 1st, which gives proactive parents plenty of time to stock up for the holidays. Unfortunately, the price seems to have inched up by a Jackson, as it's currently up for pre-order at $99.99. Rest assured, however, that said price is far less than what you'll pay on eBay if you're empty-handed come December 20th.

Honda's ASIMO could be thought controlled in Spaceballs 2

by Thomas Ricker, posted Mar 31st 2009 at 3:31AM

Sorry, that's not actually Dark Helmet, it's a researcher demonstrating the latest Brain Machine Interface (BMI) cooked up for robotics. While it's not looking too portable, it's a far nimbler setup than the original MRI Scanner first concocted by Honda to control robots in near real-time back in 2006. This time, Honda Research Institute in coordination with Advanced Telecommunications Research (ATR) and Shimadzu Corporation have achieved robotic thought control using a sensor cap to measure electrical potential on the scalp and cerebral blood flow. While we've seen much of this BMI tech applied to video games in the past, Honda claims its technology achieves the world's highest accuracy at 90% without special training. Impressive, even though it's clearly R&D work for now. Check the video after the break.

Researchers tout progress in creating a brain on a chip

by Donald Melanson, posted Mar 24th 2009 at 2:21PM

Mimicking the human brain has long been near the top of the list of dream projects for many a sci-fi-inspired scientist, and it looks like one team involved in the EU-supported FACETS initiative is now making some real, if still preliminary progress in the field. Apparently, they've built upon some recent mapping and modeling research and created an actual chip (or, more specifically a 20cm wafer), which could eventually contain a network of 200,000 neurons and 50 million synapses. That, the researchers say, will allow for them to take on larger scale neural computing work than has previously been possible, and could even lead to "practical neural computers" in as little as five years, which they say could be particularly helpful for things like internet search -- or, you know, commanding a massive robot army.

Medtronic's implantable OCD treatment okayed by FDA

by Darren Murph, posted Feb 24th 2009 at 2:25AM

Looks like those brain pacemaker researchers are a bit late on this one, as folks at Medtronic are apt to get the jump on advanced OCD treatment given a recent FDA approval of their device. Hailed as the first implantable device "designed to deliver electrical therapy to the brain to suppress symptoms associated with severe obsessive-compulsive disorder," the Reclaim DBS (deep brain stimulation) Therapy was said to be able to treat OCD patients in cases where drugs and psychotherapy failed. Understandably, Medtronic is doing everything it can to get the product out by the middle of this year, and following up on its good fortune, it also proclaimed that it had started up a randomized clinical trial of DBS for treatment-resistant depression. There's no mention of an expected price, but apparently only 4,000 or so will be needed each year.

Japanese researchers create images from thoughts using thoughts about images

by Laura June, posted Dec 11th 2008 at 6:29PM

A team of Japanese scientists at ATR Computational Neuroscience Laboratories, led by researcher Yukiyasu Kamitani, have successfully processed and displayed reconstructed images directly from the ever-hackable human brain. In the experiments, the team first showed participants 400 different still images in order to suss out their visual thought patterns. They then showed them the letters that make up the word "neuron," and successfully reconstructed them via brain activity onto a screen. The full results of the tests are going to be published later this month in Neuron, but Dr. F. Krueger at ATR says that they think the tech could someday be used to hack into people's dreams.

DARPA enlists IBM to build computer brain as smart as a cat

by Donald Melanson, posted Nov 21st 2008 at 3:44PM

Researchers have long been trying to model actual brains in order to build a better computer "brain," and it looks like IBM is now getting a helping hand from none other than DARPA in its attempt to create one that it hopes will one day have the intelligence level of a cat. To that that somewhat unnerving end, DARPA is pouring $4.9 million into a project that'll include five universities and scientists of all stripes, who will work together to create an artificial brain that behaves like a real one right down to the neuron level. As the BBC reports, the researchers are describing this latest initiative as a "180 degree shift in perspective" from previous efforts, as they're now seeking an algorithm first and problems second, as opposed to starting with an objective and devising an algorithm to achieve it. As for DARPA's ultimate goal, well, that's still a bit of a mystery, though let's just say we won't be surprised if future robots start to become very easily distracted.

The brain-stimulating 'thinking cap': low fashion, high IQ

by Joseph L. Flatley, posted Oct 2nd 2008 at 5:12AM

In another foray into the realms of improbable brain research, mad scientists in Australia claim to have found a way to boost your intelligence to Rain Man-esque levels using magnets and something that looks like a hairnet. When inspiration is low or creativity ebbs, Sydney University researchers claim that an electromagnetic 'zap' to the left side of the brain will cause all you over-analytic, right-brained types to shift to the other hemisphere, where you will soon be writing operas, penning sonnets and proofreading like a champ. As professor Allan Snyder says: "I believe that each of us has within us non-conscious machinery which can do extraordinary art, extraordinary memory and extraordinary mathematical calculations." Really doctor? Even the guy with the "get a brain morans" sign? Okay, we'll take your word for it.

"Thought helmets" could enable voiceless troop communication

by Darren Murph, posted Sep 22nd 2008 at 9:06AM

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.

Fingercams / brain scanners to make mice and multitouch displays seem archaic

by Darren Murph, posted Sep 2nd 2008 at 6:32AM

Oh sure, we've known that mice were going the way of the Dodo for eons now, but a nice compilation over at Wired details just how close we are to relying on brain scanners and fingercams (among other unorthodox input methods) to do everything from play games to flip through photo albums. For instance, at Drexel University's RePlay Lab, students are currently "trying to measure the level of neurotransmitters in a subject's brain to create games where mere thought controls gameplay." Another example of how fingers are better used away from the left / right click is FingerSight, a technology that would enable cursor inputs to be, um, inputted by simply waving one's hand around. Unfortunately, the reality of all of this fantastic research is that we're still years away from pushing the fabled keyboard / mouse combo aside, but you aren't apt to find any FPS fanatics kvetching about that.

OCZ's Neural Impulse Actuator gets reviewed, mice everywhere safe for now

by Darren Murph, posted Jul 21st 2008 at 6:13PM

We tried to take OCZ's Neural Impulse Actuator seriously, we really did. But unable to suppress those recurring images of Geordi La Forge, we simply couldn't help ourselves from having a laugh at this thing's expense. Nevertheless, the way-more-solemn dudes and dudettes over at HotHardware managed to give this brain-computer interface a fair shake, and overall, it was pretty impressed. Still, the bottom line is this: "the NIA is a very unique input device and possibly the first true brain-computer interface to hit the retail market," but it's not "a replacement for traditional input methods." Granted, critics did point out that it would supplement current devices quite well, but only after "slogging through" hours upon hours of training. The hardcore among us may be willing to put in the time necessary to really get a lot out of this; for everyone else, just continue to point and laugh while masking your ignorance.

Researchers devise neural implant that learns over time

by Darren Murph, posted Jun 25th 2008 at 9:48AM

Brain-machine interfaces have done quite a bit in helping handicapped individuals interact with prosthetic limbs, computers and other humans, but a new neural implant concocted at the University of Florida could make all those past devices look archaic. Put simply, researchers have discovered a method that would enable brain-machine interfaces to "adapt to a person's behavior over time and use the knowledge to help complete a task more efficiently." Until now, the brain was the instrument doing all the talking while the computer simply accepted commands; with this method, "the computer could have a say in that conversation, too." In all seriousness, this type of learning mechanism could be game-changing in the world of physical therapy, but we hesitate to give something mechanical inside of our body too much free will, ya dig?

Computer designed to read thoughts from brain scans

by Darren Murph, posted May 31st 2008 at 5:10PM

Frighteningly enough, this isn't the first (or second) time that we've seen scientists pat themselves on the back for creating a mind-reading machine, but a dedicated team from Carnegie Mellon has just announced a computer that "has been trained to read people's minds by looking at scans of their brains as they thought about specific words." In a completely unsurprising move, gurus familiar with the development are suggesting that the breakthrough could be used to better understand how the brain organizes knowledge, and eventually, treat language disorders and learning disabilities more effectively. That's all gravy from here, but when this stuff starts passing as evidence in court, you'll know it's time to seriously investigate a relocation to Mars.

Researchers cram bio-signal monitoring system inside baseball cap

by Darren Murph, posted May 17th 2008 at 11:38PM

Never before has headgear been so intrinsically linked with actual brain waves. Thanks to a team of researchers looking to create a method for "continuously monitoring high-temporal resolution brain dynamics without requiring conductive gels applied to the scalp," a new baseball cap has been created to do the trick. Said hat conceals five embedded dry electrodes which contact the wearer's forehead, while a single electrode behind the left ear acquires EEG signals. From there, the data is transferred wirelessly and can be processed in real-time to determine a driver's level of drowsiness, for instance. The gurus behind the invention have high hopes for its future, and they've already envisioned it being used in a plethora of medical scenarios and for controlling home electronics. To those about to rock this -- prepare for some serious hat-hair.

"Brain pacemaker" could treat depression, OCD

by Nilay Patel, posted Apr 29th 2008 at 1:46AM

Sending electrical shocks into the brain via a "brain pacemaker" has already led to dramatic breakthroughs like the revival of a man trapped in a vegetative state for six years, but new research may mean that the technique is soon a common treatment for disorders like depression and OCD. Researchers from the Cleveland Clinic, Mass General, Harvard Medical School and Brown Medical School implanted the Medtronics brain pacemaker into 17 people suffering from depression and tracked them for a year, finding significant improvements in mood as well as social and occupational functioning, while 26 patients suffering from OCD were followed for three years and also showed "marked improvement." Findings will be presented to the American Association of Neurological Surgeons this week in Chicago, and clinical trials are scheduled for later this year -- in other news, sales of "The Terminal Man" to neurosurgeons recently skyrocketed for unknown reasons.

Fruit fly flight simulator could smarten up robots

by Darren Murph, posted Apr 26th 2008 at 10:42AM

Wondering just how we mere mortals were going to even give a robot enough smarts to completely overtake our societies? Oddly enough, some of that artificial brain power could come from studying the way fruit flies, um, fly. A completely bizarre flight simulator at Caltech actually plays "scenes" that flys react to, and considering that the fly is constantly held, researchers can closely examine how the insect attempts to navigate away from lines, blobs and all manners of incoming obstacles. Those working with the installation suggest that these studies could one day help autonomous robots function better, potentially taking some of the load off of our human workforce. We know, you've got three bold letters and a question mark running through your noggin right now -- just hit the read link to see what it's all about.
