Scientists have improved upon their own previous world-best efforts to pluck out just the right stem cells to address the brain problem at the core of multiple sclerosis and a large number of rare, fatal children´s diseases. Details of how scientists isolated and directed stem cells from the human brain to become oligodendrocytes — the type of brain cell that makes myelin, a crucial fatty material that coats neurons and allows them to signal effectively — were published...

Study findings indicate a key step in the generation of white matter and understanding developmental disabilities Through the identification of a gene's impact on a signaling pathway, scientists at Children's National Medical Center continue to make progress in understanding the mechanics of a key brain developmental process: growth and repair of white matter, known as myelination. The study, published online in the September 2011 online edition of The Journal of Neuroscience, identified...

Process paves way for research, possible treatments of multiple sclerosis and more Scientists at Case Western Reserve University School of Medicine found a way to rapidly produce pure populations of cells that grow into the protective myelin coating on nerves in mice. Their process opens a door to research and potential treatments for multiple sclerosis, cerebral palsy and other demyelinating diseases afflicting millions of people worldwide. The findings will be published in the online...

A new imaging technique could help doctors and researchers more accurately assess the extent of nerve damage and healing in a live patient. Researchers at Laval University in Québec and Harvard Medical School in Boston aimed lasers at rats' damaged sciatic nerves to create images of the individual neurons' insulating sheath called myelin. Physical trauma, repetitive stress, bacterial infections, genetic mutations, and neurodegenerative disorders such as multiple sclerosis can all...

Narcolepsy is a rare disorder characterized by an excessive urge to sleep at inappropriate times and places. Narcoleptics are also often subject to "cataplexy," a sudden muscle weakness that is triggered by strong emotions. Although most cases of narcolepsy are thought to be caused by complex mechanisms, a small percentage of cases are associated with unidentified inherited mutations. Now, a new study published by Cell Press on September 8th in the American Journal of Human Genetics uncovers...

Like explorers mapping a new planet, scientists probing the brain need every type of landmark they can get. Each mountain, river or forest helps scientists find their way through the intricacies of the human brain. Researchers at Washington University School of Medicine in St. Louis have developed a new technique that provides rapid access to brain landmarks formerly only available at autopsy. Better brain maps will result, speeding efforts to understand how the healthy brain works and...

Computer scientists at Brown University have created software to examine neural circuitry in the human brain. The 2-D neural maps combine visual clarity with a Web-based digital map interface, and users can view 2-D maps together with 3-D images. The program aims to better understand myelinated axons, which have been linked to pathologies such as autism. Results are published in IEEE Transactions on Visualization and Computer Graphics. Medical imaging systems allow neurologists to summon 3-D...

Researchers including members from the Niels Bohr Institute at the University of Copenhagen have developed a new method for making detailed X-ray images of brain cells. The method, called SAXS-CT, can map the myelin sheaths of nerve cells, which are important for conditions such as multiple sclerosis and Alzheimer's disease. The results have been published in the scientific journal, NeuroImage. The myelin sheaths of nerve cells are lamellar membranes surrounding the neuronal axons. The myelin...

This finding has particular importance because several neurodevelopmental disorders have recently been linked to genetic mutations in the complex developmental cascade containing Erk and its sister proteins. Researchers at the University of North Carolina at Chapel Hill have pinpointed a crucial function for a key player in the development of the nervous system. They found that this player "“ a protein called Erk "“ is necessary for nerve fibers to be wrapped with an insulating...
