World-leading experts in Magnetic Resonance Imaging from The University of Nottingham´s Sir Peter Mansfield Magnetic Resonance Centre have made a key discovery which could give the medical world a new tool for the improved diagnosis and monitoring of neuro-degenerative diseases like multiple sclerosis. The new study, published in the Proceedings of the National Academy of Science, reveals why images of the brain produced using the latest MRI techniques are so sensitive to the...

Brain Power, Not Muscle Strength Related To Force Of Karate Punch
2012-08-16 12:29:05

Connie K. Ho for redOrbit.com — Your Universe Online Brain scans of karate experts recently showed distinctive features. Researchers believe that the images show how the ability to punch for black belts and karate novices could be related to a certain feature in the brain. The researchers, hailing from Imperial College London and University College London, discovered differences in the structure of the connection between brain regions, otherwise known as white matter. To begin,...

Highways Of The Brain

A new study proposes a communication routing strategy for the brain that mimics the American highway system, with the bulk of the traffic leaving the local and feeder neural pathways to spend as much time as possible on the longer, higher-capacity passages through an influential network of hubs, the so-called rich club. The study, published this week online in the Early Edition of the Proceedings of the National Academy of Sciences, involves researchers from Indiana University and the...

Double Positive Punch In Brain White Matter Prompted By Chinese Meditation
2012-06-12 06:46:04

Scientists studying the Chinese mindfulness meditation known as integrative body-mind training (IBMT) say they've confirmed and expanded their findings on changes in structural efficiency of white matter in the brain that can be related to positive behavioral changes in subjects practicing the technique regularly for a month. In a paper appearing this week in the online Early Edition of the Proceedings of the National Academy of Sciences, scientists Yi-Yuan Tang and Michael Posner report...

Patients vary widely in their response to concussion, but scientists haven't understood why. Now, using a new technique for analyzing data from brain imaging studies, researchers at Albert Einstein College of Medicine of Yeshiva University and Montefiore Medical Center have found that concussion victims have unique spatial patterns of brain abnormalities that change over time. The new technique could eventually help in assessing concussion patients, predicting which head injuries are...

Even when brain injury is so subtle that it can only be detected by an ultra-sensitive imaging test, the injury might predispose soldiers in combat to post-traumatic stress disorder, according to a University of Rochester Medical Center study. The research is important for physicians who are caring for troops in the years following deployment, as they try to untangle the symptom overlap between PTSD and mild traumatic brain injury (mild TBI) and provide the appropriate treatment. Until...

University of Georgia researchers have developed a map of the human brain that shows great promise as a new guide to the inner workings of the body's most complex and critical organ. With this map, researchers hope to create a next-generation brain atlas that will be an alternative option to the atlas created by German anatomist Korbinian Brodmann more than 100 years ago, which is still commonly used in clinical and research settings. Tianming Liu, assistant professor of computer...

Breakdown of white-matter pathways affects decision-making as we age If you are an aging baby boomer and you've noticed it's a bit harder to drive to unfamiliar locations or to pick a new brand of olive oil at the supermarket, you can blame it on the white matter in your brain. A brain-mapping study, published in the Apr. 11 issue of The Journal of Neuroscience, has found that people's ability to make decisions in novel situations decreases with age and is associated with a reduction in...

Researchers have mapped brain nerves and have found them to be laid out in a three-dimensional grid. Mapping out these nerves will provide a greater insight into the inner-workings of the brain, as well as allow doctors to more precisely diagnose psychiatric and neurological disorders. Van Wedeen, MD, of Massachusetts General Hospital led the research team who conducted this study. The results have been compared to a “bowl of spaghetti," a “chess board," and “a New York...

Scans reveal astonishingly simple 3D grid structure -- NIH-funded study The brain appears to be wired more like the checkerboard streets of New York City than the curvy lanes of Columbia, Md., suggests a new brain imaging study. The most detailed images, to date, reveal a pervasive 3D grid structure with no diagonals, say scientists funded by the National Institutes of Health. "Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables --...
