Penn researchers engineer first system of human nerve-cell tissue
Researchers at the University of Pennsylvania School of Medicine have demonstrated that living human nerve cells can be engineered into a network that could one day be used for transplants to repair damaged to the nervous system. They report their findings in the February issue of the Journal of Neurosurgery. view more (2008-02-27)
Research scientists discover gene defect responsible for epilepsy
Some 70 million people world-wide suffer from what is known as idiopathic epilepsy. The symptoms can vary considerably, ranging from brief unconsciousness and twitching of arms or legs to serious attacks of cramp. Research scientists at the Universities of Bonn, Ulm and Aachen have now been able to identify a gene that - if not properly... view more... (2003-02-27)
Study helps explain why botulinum toxin is so deadly
A pilot without a map can locate an airport by first finding a nearby landmark, like a big river, and then searching for the airport. view more (2006-12-14)
Long-lasting Nerve Block Could Change Pain Management
Researchers at Children's Hospital Boston have developed a slow-release anesthetic drug-delivery system that could potentially revolutionize treatment of pain during and after surgery, and may also have a large impact on chronic pain management. view more (2009-04-16)
Models of eel cells suggest electrifying possibilities
Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at Yale University and the National Institute of Standards and Technology (NIST) takes it to a cellular level. view more (2008-10-03)
Your brain cells may 'know' more than you let on by your behavior
We often make unwise choices although we should know better. Thunderstorm clouds ominously darken the horizon. We nonetheless go out without an umbrella because we are distracted and forget. view more (2005-10-20)
Researchers close in on origins of main ingredient of Alzheimer's plaques
The ability of brain cells to take in substances from their surface is essential to the production of a key ingredient in Alzheimer's brain plaques, neuroscientists at Washington University School of Medicine in St. Louis have learned. view more (2008-04-10)
New source of multipotent adult stem cells discovered in human hair follicles
Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types. view more (2006-07-13)
Researchers discover a protein responsible for shaping the nervous system
A team of researchers led by The Hospital for Sick Children (SickKids), the University of Toronto (U of T) and Cold Spring Harbor Laboratory have discovered a protein that is responsible for shaping the nervous system. view more (2005-12-08)
Wellcome Trust grant to investigate degenerative brain diseases known as `tauopathies`
Dr Julian Thorpe, head of the Electron Microscopy Lab at the University of Sussex, will be working towards a better understanding of degenerative brain diseases thanks to a £247,000 grant from the Wellcome Trust. He is taking a very close look at a possible contributory cause of nerve cell death in a group of conditions related to... view more... (2002-04-17)
Widely used iron nanoparticles exhibit toxic effects on neuronal cells
Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions. view more (2007-03-29)
JHU researcher discovers brain cells have 'memory'
As we look at the world around us, images flicker into our brains like so many disparate pixels on a computer screen that change every time our eyes move, which is several times a second. Yet we don't perceive the world as a constantly flashing computer display. view more (2009-04-03)
A new metal detector to study human disease
Zinc may be a familiar dietary supplement to millions of health-conscious people, but it remains a mystery metal to scientists who study zinc's role in Alzheimer's disease, stroke and other health problems. view more (2006-03-22)
Test reveals effectiveness of potential Huntington's disease drugs
A test using cultured cells provides an effective way to screen drugs against Huntington's disease and shows that two compounds - memantine and riluzole - are most effective at keeping cells alive under conditions that mimic the disorder, UT Southwestern Medical Center researchers report. view more (2006-10-30)
Bisexual fruit flies show new role for neurochemical
Fruit flies' ability to discern one sex from another may depend on the number of receptors on the surface of nerve cells, and the number of receptors is controlled by levels of a ubiquitous brain chemical, University of Illinois at Chicago researchers have found. view more (2007-01-04)
Tarantula venom and chili peppers target same pain sensor
Venom from a West Indian tarantula has been shown to cause pain by exciting the same nerve cells in mice that sense high temperatures and the hot, spicy ingredient in chili peppers. view more (2006-11-09)
Nanotubes used for first time to send signals to nerve cells
Texas scientists have added one more trick to the amazing repertoire of carbon nanotubes - the ability to carry electrical signals to nerve cells. view more (2006-05-09)
Researchers link early stem cell mutation to autism
In a breakthrough scientific study published today in the Proceedings of the National Academy of Sciences, scientists at the Burnham Institute for Medical Research have shown that neural stem cell development may be linked to Autism. view more (2008-07-01)
Copper circuits help brain function — could tweaking the circuits make us smarter?
The flow of copper in the brain has a previously unrecognized role in cell death, learning and memory. view more (2006-09-26)
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)
