Brain's white matter -- More 'talkative' than once thought
05-06-2007 · EurekAlert!Johns Hopkins scientists have discovered to their surprise that nerves in the mammalian brain’s white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do.

- 'Fetal' neurons play role in adult brain
09-11-2007 · EurekAlert!
Subplate neurons -- once thought to die after directing the wiring of the cerebral cortex or gray matter -- remain in the white matter of the adult brain in small numbers and maintain activity, communicating with other neurons in the brain said researchers from Baylor College of Medicine and the University of Alabama at Birmingham in a report that appears in today's issue of the Journal of Neuroscience.

- Slow reading in dyslexia tied to disorganized brain tracts
12-03-2007 · EurekAlert!
Researchers at Children's Hospital Boston and Beth Israel Deaconess Medical Center have found that difficulty in reading smoothly, or fluently, which occurs in some types of dyslexia, may be caused by disorganized, meandering tracts of nerve fibers in the brain. The findings, which point to organized white matter as the structural basis in the brain for fluent reading, could help specialists find new ways to improve the automatic nature of reading in individuals with dyslexia.

- Brain abnormalities discovered in people who have trouble reading fast
12-03-2007 · EurekAlert!
Some people who have problems reading quickly appear to have abnormalities in the white matter of their brains, according to research published in the Dec. 4, 2007, issue of Neurology, the medical journal of the American Academy of Neurology. Researchers say these findings provide a model to better understand ways in which the brain may have developed differently in people with learning disabilities.

- Study Identifies Part Of Brain Responsible For Tone Deafness
09-29-2006 · ScienceDaily
A new study has discovered that the brains of people suffering from tone-deafness are in fact lacking in white matter. The study published in the current issue of Brain was conducted by a team of researchers from the Université de Montréal, the Montreal Neurological Institute and the Newcastle University Medical School.

- Children's scientists discover fundamental protein instrumental to brain development and repair
07-08-2007 · EurekAlert!
Scientists at Children's National Medical Center have demonstrated conclusively that a specific protein and its signaling activity are instrumental in myelination and remyelination, processes essential to the creation and repair of the brain's white matter. This groundbreaking discovery in mouse models points the way to developing treatments to enhance healthy brain development and/or brain disease repair in children and adults.

- Pedophilia may be the result of faulty brain wiring
11-28-2007 · EurekAlert!
Pedophilia might be the result of faulty connections in the brain. A new study from CAMH showed that pedophiles had significantly less "white matter." The study challenges the commonly held belief that pedophilia is brought on by childhood trauma or abuse. This finding is the strongest evidence yet that pedophilia is instead the result of a problem in brain development.

- New particles get a mass boost
10-01-2007 · EurekAlert!
A sophisticated, new analysis has revealed that the next frontier in particle physics is farther away than once thought. New forms of matter not predicted by the Standard Model of particle physics are most likely twice as massive as theorists had previously calculated, according to a just-published study.

- Study discovers link between increased white matter and poor motor skills in children with autism
07-30-2007 · EurekAlert!
A study published in the August issue of the journal Brain demonstrates, for the first time, an association between increased white matter volume and functional impairment in children with autism. Findings from researchers at the Kennedy Krieger Institute in Baltimore, Md., reveal that in children with autism, increased white matter volume in the motor region of the brain predicts poorer motor skills.

- New understanding of schizophrenia could lead to new treatment approaches
04-23-2007 · EurekAlert!
New research helps bridge an important gap in understanding schizophrenia, providing the best evidence to date that defects in the brain's white matter are a key contributor to the disease, which affects about 1 percent of people worldwide. The findings, to be published online by the Proceedings of the National Academy of Sciences, also demonstrate how two of the dozen or more genes previously linked with schizophrenia may contribute to the disease.
