Highways Of The Brain
2012-06-18 15:34:49

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 --...

A powerful new imaging technique called High Definition Fiber Tracking (HDFT) will allow doctors to clearly see for the first time neural connections broken by traumatic brain injury (TBI) and other disorders, much like X-rays show a fractured bone, according to researchers from the University of Pittsburgh in a report published online today in the Journal of Neurosurgery. In the report, the researchers describe the case of a 32-year-old man who wasn't wearing a helmet when his all-terrain...

Innovative magnetic resonance imaging (MRI) techniques that can measure changes in the microstructure of the white matter likely to affect brain function and the ability of different regions of the brain to communicate are presented in an article in the groundbreaking new neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc.. The article is available free online at www.liebertpub.com/brain Brain function depends on the ability of...
