Brain-Computer Interface Allows Patients To Control Robotic Limbs
2013-06-12 09:56:08

redOrbit Staff & Wire Reports - Your Universe Online Electrodes placed on or inside the brain allow patients to interact with computers or control robotic limbs by merely thinking about how to execute those actions, University of Washington researchers reported on Tuesday. The technology could improve the quality of life for people who are paralyzed or lack the ability to speak due to stroke or neurodegenerative disease by allowing them to control a robotic arm or a prosthetic limb...

Study Shows Where Scene Context Happens In Our Brain
2013-05-21 13:17:48

University of California - Santa Barbara In a remote fishing community in Venezuela, a lone fisherman sits on a cliff overlooking the southern Caribbean Sea. This man —— the lookout —— is responsible for directing his comrades on the water, who are too close to their target to detect their next catch. Using abilities honed by years of scanning the water's surface, he can tell by shadows, ripples, and even the behavior of seabirds, where the fish are schooling, and...

Brain Trauma Diagnostics Transformed Using Wireless Signals
2013-05-15 08:15:36

University of California, Berkeley New technology developed at the University of California, Berkeley, is using wireless signals to provide real-time, non-invasive diagnoses of brain swelling or bleeding. The device analyzes data from low energy electromagnetic waves that are similar to those used to transmit radio and mobile signals. The technology, described in the May 14 issue of the journal PLOS ONE, could potentially become a cost-effective tool for medical diagnostics and to...

Frontal Lobe May Not Be Key To Intelligence After All
2013-05-14 08:56:44

redOrbit Staff & Wire Reports - Your Universe Online The frontal lobes are not disproportionately larger compared to other regions of the brain, suggesting other areas of the brain may play a role in humans´ unique cognitive abilities, according to new research published Monday in the Proceedings of the National Academy of Sciences (PNAS). Researchers from Durham University and Reading University compared the size of the frontal lobes — regions of a...

Scientists Look At How The Brain Compensates For Speed
2013-05-08 18:47:22

Michael Harper for redOrbit.com — Your Universe Online Researchers from the University of California in Berkeley have finally pinpointed the area of the brain responsible for not only seeing fast-moving objects, but responding to them as well. This development explains why athletes are able to react and respond to balls traveling at speeds upwards of 100 miles an hour. According to this research, our brains are capable of “pushing” fast moving objects, so we perceive...

Virginia Tech scientists bring clarity to how most Alzheimer's drugs sharpen brain performance Scientists at the Virginia Tech Carilion Research Institute have discovered how the predominant class of Alzheimer's pharmaceuticals might sharpen the brain's performance. One factor even more important than the size of a television screen is the quality of the signal it displays. Having a life-sized projection of Harry Potter dodging a Bludger in a Quidditch match is of little use if the...

Mathematicians from Queen Mary, University of London will bring researchers one-step closer to understanding how the structure of the brain relates to its function in two recently published studies. Publishing in Physical Review Letters the researchers from the Complex Networks group at Queen Mary´s School of Mathematical Sciences describe how different areas in the brain can have an association despite a lack of direct interaction. The team, in collaboration with researchers in...

Scientists at the Stanford University School of Medicine have determined the precise anatomical coordinates of a brain "hot spot," measuring only about one-fifth of an inch across, that is preferentially activated when people view the ordinary numerals we learn early on in elementary school, like "6" or "38." Activity in this spot relative to neighboring sites drops off substantially when people are presented with numbers that are spelled out ("one" instead of "1"), homophones ("won"...
