Cause of nerve fiber damage in multiple sclerosis identified
Researchers have identified how the body's own immune system contributes to the nerve fiber damage caused by multiple sclerosis, a finding that can potentially aid earlier diagnosis and improved treatment for this chronic disease. view more (2006-10-17)
Identification of a key gene required for brain neural circuit formation
An international team of scientists, lead by Dr. Frederic Charron at the IRCM, and Drs Ami Okada, Sue McConnell, and Marc Tessier-Lavigne in the USA, have made a discovery which could help treat spinal cord injuries and neurodegenerative diseases. view more (2006-11-02)
New hope for stroke patients
If a stroke patient doesn't get treatment within approximately the first three hours of symptoms, there's not much doctors can do to limit damage to the brain. view more (2008-08-26)
Rare genetic disorder gives clues to autism, epilepsy, mental retardation
A rare genetic disorder called tuberous sclerosis complex (TSC) is yielding insight into a possible cause of some neurodevelopmental disorders: structural abnormalities in neurons, or brain cells. view more (2008-09-24)
Different approach needed to protect brains of premature infants
A study of how the brain of a premature infant responds to injury has found vulnerabilities similar to those in the mature brain but also identified at least one significant difference, according to neuroscientists and neonatologists at Washington University School of Medicine in St. Louis. view more (2007-04-11)
Nanowire arrays can detect signals along individual neurons
Opening a whole new interface between nanotechnology and neuroscience, scientists at Harvard University have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of live mammalian neurons. view more (2006-08-25)
Bone marrow cell transplants help nerve regeneration
A study carried out by researchers at the Kyoto University School of Medicine and published in the current issue of CELL TRANSPLANTATION (Vol.16 No. 8) has shown that when transplanted bone marrow cells (BMCs) containing adult stem cells are protected by a 15mm silicon tube and nourished with bio-engineered materials, they successfully help... view more...

New roles for growth factors: Enticing nerve cells to muscles
During embryonic development, nerve cells hesitantly extend tentacle-like protrusions called axons that sniff their way through a labyrinth of attractive and repulsive chemical cues that guide them to their target. view more (2006-06-16)
Standing up to paraplegia with gene therapy
Elena Rugarli and colleagues from the National Neurological Institute in Milan have used gene therapy to save sensory and skeletal muscle nerve fibers from degeneration in mice with hereditary spastic paraplegia (HSP). view more (2005-12-16)
Most important actors in the growth process of neurons identified
Defects in the growth process of our neurons often underlie brain or nerve diseases, such as Alzheimer's disease or multiple sclerosis. view more (2006-10-12)
Pathways of emotion - from cortex to peripheral organs
Walking down a dark alley late at night is enough to give anyone the heebie-jeebies. Your heart starts racing, your palms get clammy and you get ready to run. Now researchers from Boston University have unravelled the neural pathways that transmit information about your surroundings to your organs, enabling them to respond appropriately. The... view more... (2003-10-07)
Brain works more chaotically than previously thought
The brain appears to process information more chaotically than has long been assumed. This is demonstrated by a new study conducted by scientists at the University of Bonn. view more (2007-02-28)
A second career for a growth factor receptor: keeping nerve axons on target
Neurons constituting the optic nerve wire up to the brain in a highly dynamic way. Cell bodies in the developing retina sprout processes, called axons, which extend toward visual centers in the brain, lured by attractive cues and making U-turns when they take the wrong path. view more (2008-09-12)
Gradient guides nerve growth down spinal cord
The same family of chemical signals that attracts developing sensory nerves up the spinal cord toward the brain serves to repel motor nerves, sending them in the opposite direction, down the cord and away from the brain. view more (2005-08-15)
Drug studied as possible treatment for spinal injuries
Researchers have shown how an experimental drug might restore the function of nerves damaged in spinal cord injuries by preventing short circuits caused when tiny "potassium channels" in the fibers are exposed. view more (2009-11-20)
Scientists Shed Light on Long-Distance Signaling in Developing Neurons
A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus. view more (2008-02-20)
Major breakthrough in the mechanism of myelin formation
The group of Dr. Michel Cayouette, researcher at Institut de recherches cliniques de Montréal (IRCM), and Dr. Jonah Chan, collaborator at the University of Southern California, will publish in the next issue of the prestigious scientific journal Science, the results of their study that could have a major impact on the treatment of diseases... view more...

Can a vitamin alleviate chronic, progressive multiple sclerosis?
Researchers have found a possible way to protect people with multiple sclerosis (MS) from severe long-term disability: increase nervous-system levels of a vital compound, called nicotinamide adenine dinucleotide (NAD), by giving its chemical precursor - nicotinamide, a form of vitamin B3. view more (2006-09-20)
Chemical signaling helps regulate sensory map formation in the brain
Researchers from the University of Chicago have uncovered an important mechanism used by the developing brain to pattern nerve connections in the part of the brain that interprets visual signals. view more (2006-01-05)
Stem cells found in adult skin can be transplanted and function in mouse models of disease
Researchers at The Hospital for Sick Children (SickKids) and the University of Calgary have found that stem cells derived from adult skin can create neural cell types that can be transplanted into and function in mouse models of disease. view more (2006-06-15)
