Researchers look to armadillos, fruit flies, nematodes, and other species to understand human brain function and vision loss Research released today reveals a new model for a genetic eye disease, and shows how animal models — from fruit flies to armadillos and monkeys — can yield valuable information about the human brain. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain...

UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness. Their research, published Oct. 17 in the online journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness. "In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving from Los Angeles to New York in a straight line versus having to cover...

A new study has discovered profound abnormalities in brain activity in a group of retired American football players. Although the former players in the study were not diagnosed with any neurological condition, brain imaging tests revealed unusual activity that correlated with how many times they had left the field with a head injury during their careers. Previous research has found that former American football players experience higher rates of neurodegenerative diseases such as...

In a breakthrough for understanding brain evolution, neuroscientists have shown that differences between primate brains - from the tiny marmoset to human – can be largely explained as consequences of the same genetic program. In research published in the Journal of Neuroscience, Professor Marcello Rosa and his team at Monash University's School of Biomedical Sciences and colleagues at Universidade Federal do Rio de Janeiro, in Brazil, used computer modelling to demonstrate that the...

Chronic Dizziness May Be Helped By Magnetic Stimulation

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Johns Hopkins University School of Medicine believe that they have located a specific site in the human brain that could be one of the sources of dizziness and spatial disorientation. While dizziness can also be linked to damage to the inner ear, or to other senses such as vision, neurology instructor Dr. Amir Kheradmand and his colleagues report that they have discovered a region of the brain that plays a...

Our brains give us the remarkable ability to make sense of situations we've never encountered before—a familiar person in an unfamiliar place, for example, or a coworker in a different job role—but the mechanism our brains use to accomplish this has been a longstanding mystery of neuroscience. Now, researchers at the University of Colorado Boulder have demonstrated that our brains could process these new situations by relying on a method similar to the "pointer" system used by...

Is this my finger? People can be easily tricked into believing an artificial finger is their own, shows a study published today [23 September] in The Journal of Physiology. The results reveal that the brain does not require multiple signals to build a picture body ownership, as this is the first time the illusion has been created using sensory inputs from the muscle alone. The discovery provides new insight into clinical conditions where body representation in the brain is disrupted due...

Neurofeedback Can Enhance The Brain's Signal-to-noise Ratio

April Flowers for redOrbit.com - Your Universe Online As a needle sweeps across the grooves of a worn vinyl record, it carries the distinct sounds of hisses, scratches and even the echo of skips. For many years, however, if someone yearned to hear Frank Sinatra sing "Fly Me to the Moon," they were able to listen to his crooning baritone with technical clarity, courtesy of the increased signal-to-noise ratio of digital re-masterings. Recent advances in neurofeedback techniques have made...

Active brain state beyond the deep coma associated with a flat EEG Researchers from the University of Montreal and their colleagues have found brain activity beyond a flat line EEG, which they have called Nu-complexes (from the Greek letter Νν). According to existing scientific data, researchers and doctors had established that beyond the so-called "flat line" (flat electroencephalogram or EEG), there is nothing at all, no brain activity, no possibility of life. This major discovery...

Bird Brain Map Gets Major Revisions

Brett Smith for redOrbit.com - Your Universe Online Using state-of-the-art genetic and diagnostic tools, researchers from Duke University and the University of California, San Diego have re-contextualized the map of the avian brain, as described to two separate papers published in the Journal of Comparative Neurology. The researchers noted many similarities between the avian brain and mammalian brain – leading them to conclude that all vertebrates have more in common with respect to...
