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...

Scientists at the University of Kentucky's College of Medicine have identified changes in the brains of normal individuals at high risk for Alzheimer's disease that could prove important for early detection of the disease. The research, led by Brian Gold, associate professor of anatomy and neurobiology, focused on the brain's white matter, which forms the majority of deep parts of the brain and consists primarily of myelinated nerve cell processes, or axons. These myelinated axons serve to...

Highly fit multiple sclerosis patients perform significantly better on tests of cognitive function than similar less-fit patients, a new study shows. In addition, MRI scans of the patients showed that the fitter MS patients showed less damage in parts of the brain that show deterioration as a result of MS, as well as a greater volume of vital gray matter. "We found that aerobic fitness has a protective effect on parts of the brain that are most affected by multiple sclerosis," said Ruchika...

Fewer African Americans than Caucasians develop multiple sclerosis (MS), statistics show, but their disease progresses more rapidly, and they don't respond as well to therapies, a new study by neurology researchers at the University at Buffalo has found. Magnetic resonance images (MRI) of a cohort of 567 consecutive MS patients showed that blacks with MS had more damage to brain tissue and had less normal white and gray matter compared to whites with the disease. Results of the study were...

Study shows reading remediation improves children's reading skills and positively alters brain tissue Carnegie Mellon University scientists Timothy Keller and Marcel Just have uncovered the first evidence that intensive instruction to improve reading skills in young children causes the brain to physically rewire itself, creating new white matter that improves communication within the brain. As the researchers report today in the journal Neuron, brain imaging of children between the ages of 8...

For years, researchers have suggested teens who exhibit risky and destructive behaviors may be influenced by underdeveloped brains. New research suggests just the opposite. A new study suggests teenagers who engage in risky behaviors develop more mature white matter tracts in the brain at a younger age. Normally, by a person's mid-twenties, white matter becomes dense and organized, signaling full maturity of the brain. In the study, conducted at Emory University and the Emory School of...

A new study using brain imaging to study teen behavior indicates that adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.The brain goes through a course of maturation during adolescence and does not reach its adult form until the mid-twenties. A long-standing theory of adolescent behavior has assumed that this delayed brain maturation is the cause of impulsive and dangerous decisions in adolescence....

Abnormalities in the fibers connecting different brain areas may contribute to muscle disorders such as writer's cramp, according to a report in the April issue of Archives of Neurology, one of the JAMA/Archives journals.Previous studies of individuals with writer's cramp have identified changes in the gray matter of several brain areas, according to background information in the article. These include the basal ganglia (structures that help control and start movement), sensorimotor cortex...

UCLA researchers find that genes determine brain's processing speedThey say a picture tells a thousand stories, but can it also tell how smart you are? Actually, say UCLA researchers, it can.In a study published in the Journal of Neuroscience Feb. 18, UCLA neurology professor Paul Thompson and colleagues used a new type of brain-imaging scanner to show that intelligence is strongly influenced by the quality of the brain's axons, or wiring that sends signals throughout the brain. The faster...

jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
