Prosthetic, robotic 'Smart Hand' has feelings, too

by Laura June posted Oct 24th 2009 at 12:42PM

Researchers in Italy and Sweden have spent the last ten years developing what they call the "Smart Hand," a prosthetic hand which enables feeling in its fingertips. The hand -- which was recently wired up to a test patient through a surgical procedure -- has four motors and forty sensors which are linked directly to the brain. In the surgery, the nerve endings of the patient were linked up to receptors in the hand, which allows for feeling in the fingertips of the hand, even though the hand is not really a part of his body. In the video after the break, you can see the greater precision and dexterity this hand allows for. Though the research still needs to be refined before practical use, it looks pretty far along -- and pretty awesome -- to us.

Optogenetics hold the key to future brain disease cures, still creep us out

by Vladislav Savov posted Oct 21st 2009 at 10:26AM

Those mad neuroscientists, they'll never learn, but maybe in the end we'll all be better off for it. Wired has put together an extremely intriguing write-up of the short history of optogenetics -- featuring a German pond scum researcher, a Nobel Prize winner, and rat brains controlled by beams of light. Optogenetics is a relatively new technique for communicating with the brain, which involves the implantation of particular light-sensitive genes into animals with the purpose of repairing neurological ailments through light therapy (no, not that kind). By hooking up fiber-optic cables to the affected area of the brain, researchers have been able to completely restore movement in mice with Parkinson's disease and their current efforts revolve around developing a less invasive method that doesn't go deeper than the outer surface of the brain. Most revolutionary of all, perhaps, is the eventual possibility for two-way traffic (i.e. a machine being able to both send and receive information from the brain), which brings all those cyborg dreams of ours closer to becoming a reality than ever before.

Mice run through Quake, Princeton neuroscientists scan their brains for traces of evil (video)

by Vladislav Savov posted Oct 15th 2009 at 8:54AM

Want to know just how prevalent technology has become in our lives? Now even lab mice get Quake-derived virtual reality playgrounds to navigate instead of their old school wooden mazes. In all honesty, this appears a significant and praiseworthy advancement, as the Princeton team have succeeded in mapping brain activity right down to the cellular level, with real-time tracking of single neurons now possible. The Orwellian-looking setup above is necessary in order to keep the mouse's head immobile, and thus capable of being studied, while the animal moves around and its brain performs motion-related tasks. Go past the break to see a schematic of the scanner and a quite unmissable video of it in action.

Mattel's Mindflex: now stressing brain muscles for $80

by Darren Murph posted Sep 18th 2009 at 8:10AM

It's taken nine whole months for this mental-stresser to go from CES show-stopper to household mainstay, but at long last, the only Mattel product we could ever recommend (with a straight face) to those with an age larger than 12 is finally shipping. In short, the Mindflex forces your brain -- as in, that hunk of meat between your ears -- to keep a ball suspended in the air, and if you're thinking Matrix, you're thinking correctly. Sort of. Hit the read link to get your own for $79.99, and make sure you do so before these things sell out and break the $1,000 mark on eBay. It's almost the holidays, don'tcha know?

Tetris players found to have greater brain efficiency, thicker cortex and better hair

by Darren Murph posted Sep 1st 2009 at 10:44AM

You just knew all that Tetris playing you did ~~as a kid~~ yesterday was good for you, huh? A new study published by the big thinkers at Mind Research Network has found that "practicing Tetris" can actually improve brain efficiency and lead to a thicker cortex in other areas of the tabula rasa. In short, the study was done in order to show that the brain can change with stimulation, and that "a challenging visuospatial task has an impact on the structure of the cortex." Of course, this is far from the first published report to use the quarter century-old title as its testing tool, but it's certainly one of the best for getting your mum and pop to believe gaming really is good for the gord. Hit up the read links below for all the details -- you know they'll be firing off questions when you hit 'em with this.

BrainPort lets you see with your tongue, might actually make it to market

by Vladislav Savov posted Aug 14th 2009 at 2:10PM

We first saw the crazy BrainPort in 2006, but the intervening time hasn't been wasted by its developers, who've brought the quirky visual aid to the cusp of commercial viability. If you'll recall, the device translates signals from a head-mounted camera to electrical pulses that lightly zap your tongue in response to visual stimuli -- early results have shown people can regain a good bit of their spatial awareness and even read large writing. The next step is FDA approval, which is expected by year's end, meaning that the BrainPort could arrive as early as 2010. There is a steep entry fee though, with prices expected to begin at $10,000, but the very fact you'll be able to buy it is a milestone in our book. Edifying video after the break.

[Thanks, Toy]

Brain Carpet microelectrodes could help translate thoughts into actions more effectively

by Laura June posted Jul 31st 2009 at 8:41PM

Researchers at the University of Utah have developed a new, more precise way of placing microelectrodes on the surface of the brain to enable patients to turn thoughts into action. Led by Bradley Greger, a professor of bioengineering, the "Brain Carpet" as it's called, represents a "modest advance" in techniques already in use. The Brain Carpet makes use of smaller microelectrodes, and also employs many more than are usually used. The method involves sawing off the skull of the patient, then placing 32 electrodes about 2mm apart on the surface of the brain. Though they've conducted tests on just a handful of patients -- all epileptics -- the technique, they believe could also be used to help people control their prosthetic limbs much more effectively. The electrodes allow detection of the electric signals in the brain which control arm and hand movements. In the tests, patients have successfully controlled a cursor on a computer screen following the operation, and they see applications for brain-machine interface devices in the future. There's no word on when the Brain Carpet will move from the research to reality phase, but the group's findings have just recently appeared in the journal Neurosurgical Focus.

The plot thickens: robot teachers to brainwash your children's children

by Darren Murph posted Jul 19th 2009 at 4:57PM

Are you ready for this? Can you stomach the truth? If things continue spiraling madly out of control as they are right now, there's at least a modicum of a chance that your children or grandchildren will greet a lifelike robot when sashaying in for the first day of kindergarten. Horrifying, we know. A new research effort published in this month's Science outlines new ways in which humanoids could actually be used to instruct our little ones. At the core of the project is imitation; humans, especially young ones, learn a multitude of mannerisms and such by simply watching others. Thus, it stands to reason that robots are "well-suited to imitate us, learn from us, socialize with us and eventually teach us." Already, these social bots are being used on an experimental basis to teach various skills to preschool children, "including the names of colors, new vocabulary words and simple songs." Just think -- in 2071, those harmless lessons will morph into studies of subterfuge, insurrection and rapacity.

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.
