Severed nerves can be made to grow again
IT IS being hailed as one of the most significant advances in nerve regeneration in a decade. After severing an optic nerve in rats, neurologists have found a way to reconnect it to the brain so that it once again transmits normal electrical signals. The achievement is a first in mammals, and may... view more... (2001-12-05)
UCSF study finds nerve regeneration is possible in spinal cord injuries
A team of scientists at UCSF has made a critical discovery that may help in the development of techniques to promote functional recovery after a spinal cord injury. view more (2005-12-02)
Amateur boxing linked to brain cell injury
A study of 14 Swedish amateur boxers suggests that they have higher levels of certain chemicals in their cerebrospinal fluid in the days following a bout, indicating injuries to neurons and other cells important to brain function. view more (2006-09-12)
USC researchers closer to cure for multiple sclerosis and other myelin-related diseases
A breakthrough finding on the mechanism of myelin formation by Jonah Chan, assistant professor of cell and neurobiology at the Keck School of Medicine of the University of Southern California, could have a major impact on the treatment of diseases such as multiple sclerosis and demyelination as a result of spinal cord injuries. view more (2006-11-03)
Findings show nanomedicine promising for treating spinal cord injuries
Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident. view more (2009-11-09)
Scientists Discover a Molecular Scaffold That Guides Connections Between Brain Cells
Brain cells known as neurons process information by joining into complex networks, transmitting signals to each other across junctions called synapses. But "neurons don't just connect to other neurons," emphasizes Z. Josh Huang, Ph.D., "in a lot of cases, they connect to very specific partners, at particular spots." view more (2008-05-21)
Protein plays Jekyll and Hyde role in Lou Gehrig's disease
Amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig's disease, is a fatal neurodegenerative disease caused by the death of motor neurons in the brain and spinal cord that control muscle movements from walking and swallowing to breathing. In a groundbreaking study this week in PLoS Biology, Brandeis and Harvard Medical School... view more... (2008-07-29)
Neurons grown from embryonic stem cells restore function in paralyzed rats
For the first time, researchers have enticed transplants of embryonic stem cell-derived motor neurons in the spinal cord to connect with muscles and partially restore function in paralyzed animals. view more (2006-06-21)
Rethinking Alzheimer's disease and its treatment targets
The standard explanation for what causes Alzheimer's is known as the amyloid hypothesis, which posits that the disease results from of an accumulation of the peptide amyloid beta, the toxic protein fragments that deposit in the brain and become the sticky plaques that have defined Alzheimer's for more than 100 years. view more (2009-09-23)
New insights into growth factor's role in brain development
New research sheds light on a neural growth factor called proBDNF, finding that it is present and potentially active during the perinatal period when the brain's circuitry and memory-encoding regions are being refined. view more (2009-02-03)
Nanomedicine opens the way for nerve cell regeneration
The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells. view more (2007-05-21)
EURYI project to understand how the brain wires during embryogenesis
One of the great questions of neurobiology, how the brain is built up during embryonic development, could be resolved by a young French scientist in an award winning project organised by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS). view more (2007-09-24)
New brain hormone puts brakes on reproduction
University of California, Berkeley, researchers have discovered a new actor in the mammalian reproductive system, a hormone that fills a role long suspected, but until now undetected. view more (2006-02-07)
Neuronal cell cultures kept on the straight and narrow
An improved technique for culturing cells, developed at the National Institute of Standards and Technology (NIST), may enable new, fundamental insights into the behavior of neuronal cells. view more (2006-05-26)
Evidence found for novel brain cell communication
An article published today, July 16, 2007, in Proceedings of the National Academy of Sciences provides strong evidence for a novel type of communication between nerve cells in the brain. The findings may have relevance for the prevention and treatment of epilepsy, and possibly in the exploration of other aspects of brain functions, from creative... view more... (2007-07-17)
MS study offers theory for why repair of brain's wiring fails
Scientists have uncovered new evidence suggesting that damage to nerve cells in people with multiple sclerosis accumulates because the body's natural mechanism for repair of the nerve coating called "myelin" stalls out. view more (2009-07-01)
Long-term changes in experience cause neurons to sprout new long-lasting connections
Howard Hughes Medical Institute researchers have discovered that neurons in the brains of mice sprout robust new connections when the animals are adjusting to new experiences. view more (2006-06-22)
RSRT Advisor Makes Significant Discovery with Potential for Novel Therapeutic Approaches
A paper published online today in Nature Neuroscience reveals the presence of methyl CpG binding protein 2 (MeCP2) in glia. MeCP2 is a protein associated with a variety of neurological disorders, including Rett Syndrome, the most physically disabling of the autism spectrum disorders. view more (2009-02-23)
Regaining Hand Control After Nerve Damage
A Swedish study published as a research letter in this week’s issue of THE LANCET concludes that the return of sensory control in the hand after nerve damage in the arm is an age-related learning process involving the central nervous system, and is similar to the processes involved in language acquisition. One of the challenges in... view more... (2001-09-05)
Scientists produce neurons from human skin
Scientists from Université Laval's Faculty of Medicine have succeeded in producing neurons in vitro using stem cells extracted from adult human skin. view more (2007-02-23)
