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...

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...

Biopsies reveal nature of brain lesions early in MS progression, countering conventional wisdom Working together, researchers at Cleveland Clinic and Mayo Clinic have for the first time examined early multiple sclerosis (MS) brain lesions in the cerebral cortex. These lesions are thought to be critical to MS progression and the researchers found that the lesions are distinctly different than previously speculated, giving clues to better disease management. The long-accepted theory has...

Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and isn't always an "inside-out" process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic. The traditional understanding is that the disease begins in the white matter that forms the bulk of the brain's inside, and extends to involve the brain's superficial layers, the cortex. Study findings support an opposite, outside-in...

(Ivanhoe Newswire) -- Soccer fans may worry more than just about making a goal. Researchers used diffusion tensor imaging, DTI, to study the effects of soccer 'heading' and found that players who head the ball with the high frequency have abnormalities similar to those found in traumatic brain injury, TBI, patients. Heading, in which players field the soccer ball with their head, is an essential part of the game and the focus of many training drills. "Heading a soccer ball is not an...

New research raises the bar on what can been seen in the brain, supports the potential of high-field MRI for early identification of tiny brain injuries in the preterm infant Pediatric neuroscientists at Oregon Health & Science University Doernbecher Children's Hospital are the first to use high magnetic field strength MRI to reveal tiny white matter injuries in the developing brain previously undetectable using standard MRI. Early, accurate identification of these lesions in the...

TORONTO, Feb. 8 /PRNewswire/ - A new study from the Centre for Addiction and Mental Health (CAMH) has found evidence suggesting that a variation of a specific gene may play a role in late-onset Alzheimer's, the disease which accounts for over 90% of Alzheimer's cases. This innovative study has combined genetics and brain imaging to determine who may be at risk for developing late-onset Alzheimer's disease long before symptoms appear. The gene, which is called brain-derived...

TAU develops genetically mutated stem cells for myelin research Vanishing White Matter (VWM) disease is a devastating condition that involves the destruction of brain myelin due to a mutation in a central factor. To understand the disease and test potential treatments that could apply to other disorders, such as multiple sclerosis, Prof. Orna Elroy-Stein of Tel Aviv University's Department of Cell Research and Immunology is leading a scientific breakthrough by developing laboratory mice which...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
