BU wizards find success in unconscious neurofeedback learning, announce plans for secret lair
You will learn French this week, even if you're not aware that it's happening. Neuroscientists at Boston University have discovered that patients can quickly learn new skills while having their brain patterns modified via decoded functional magnetic resonance imaging. The group found that pictures gradually build up inside a person's brain, appearing first as lines, edges, shapes, colors and motion in early visual areas with the brain then filling in greater details as needed to complete the object. From there, a correlation was confirmed between increased visual learning and fMRI neurofeedback, repetitions of the activation pattern leading to long-lasting performance improvement. Interestingly, the approach worked even when test subjects were not aware of what they were learning... which is why that sweater you unconsciously knitted last night should fit Johnny Boy like a glove.
Scientists reconstruct images from our brains, plan to do the same for dreams (video)
This is your brain. And now this is your brain on YouTube. By using functional magnetic resonance imaging (fMRI) software, researchers at UC Berkeley created a visual representation of what our brains see when we watch a TV or movie. It works as such: scientists show subjects random clips and measure the corresponding cerebral activity. After the computer "learns" what vids evoke what brain activity, scientists feed 18 million seconds of random YouTube videos into the computer program where it reconstructs a movie representation of neural happenings based on the hundred clips most similar to what it sees. Although the method currently only works with images actually viewed, the future goal is to recreate what people see in their dreams and memories -- which could give doctors major insight to the minds of the mentally impaired, stroke victims or those with neurological disorders. Inception in real life isn't exactly around the corner, but the implications of this new technology are pretty mind-blowing. See for yourself in the video after the break -- no totem required.
Canadian scientists scan your brain, know how you want to hold your hand
O Canada -- your wacky scientists are at it again. And this time, the bright minds over at the University of Western Ontario have their third eye set on a certain precognitive prize. Avoiding the messier open-skull, electrode-imbedding alternative, researchers at the Centre for Brain and Mind employed functional magnetic resonance imaging (fMRI) to successfully predict the action of participants' hands before they'd moved a muscle. After a year of brain-scanning trials, scientists learned to accurately foretell which signals were linked to one of three set actions: grabbing the top of an object, its bottom, or simply reaching out to touch it. Like our clairvoyant cousin's previous beverage-predicting breakthrough, the spoils of this study go to prosthetic limb motion control and the paralyzed who'll use it. We know what you're thinking, but we're not going to make the obvious Thing joke here. Instead, we have to wonder -- What Would Ms. Cleo Do? Full release after the break, but you already knew that.
