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)
Brain memory area modifies its wiring diagram during the female cycle
Researchers at Northwestern University and Columbia University have found that "wiring" in female rat brain memory area expands and retracts in relation to the amount of estrogen present during the estrous/menstrual cycle. view more (2005-11-15)
New Tools Developed for Studying Neurodegenerative Brain Disorders
Penn State researchers have created an elegantly simple model of an axon-the extension of a neuron that communicates with other neurons-and have used this model to reproduce a change in the axon's shape that is characteristic of neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. view more (2006-03-22)
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)
New microchip design could be the key to expanding mobile phone memory
Mobile phones could one day have the memory capacity of a desktop computer thanks to a microchip that mimics the functioning of the brain, scientists report today (9 September) in the journal Science. view more (2005-09-09)
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)
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)
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)
Forsyth scientists discover early key to regeneration
Science may be one step closer to understanding how a limb can be grown or a spinal cord can be repaired. Scientists at The Forsyth Institute have discovered that some cells have to die for regeneration to occur. view more (2006-12-13)
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)
Cancer-causing protein may heal damaged spinal cord and brain cells
Cancer researchers at Columbia University Medical Center have found that a protein known for driving the growth of cancer also plays a surprising role in restoring the ability of neurons to regenerate, making it an important target for addressing spinal cord damage or neurological diseases like Alzheimer's. view more (2006-06-29)
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)
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)
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)
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)
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)
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)
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...

Pular antidepressants boost brain growth, Hopkins scientists report
The beneficial effects of a widely used class of antidepressants might be the result of increased nerve-fiber growth in key parts of the brain, according to a Johns Hopkins study being published in the January 2006 issue of the Journal of Neurochemistry. view more (2005-12-20)
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)
