Combining MRI and PET Could Yield Dynamic Pictures of the BrainFriday, Apr 25, 2008
In experiments on mice, scientists report that they have successfully combined two brain imaging techniques – magnetic resonance
imaging (MRI) and positron emission tomography (PET).
New Mouse Model for Neurofibromatosis Yields Insights into Disease Process and TreatmentMonday, Apr 21, 2008
In a move expected to enhance the development of therapies for neurofibromatosis type 1, scientists have created an improved
mouse model for the disease.
Early Treatment Prevents Full-Blown Epilepsy in AnimalsFriday, Mar 14, 2008
For the first time, researchers have shown that treating epilepsy-prone animals with an anticonvulsant drug prior to the development
of chronic epilepsy can significantly reduce the number of seizures the animals experience, even after the treatment stops.
The study provides hope that researchers may eventually be able to prevent epilepsy in people who are at risk of the disorder
because of genetic mutations or other factors.
Reactions to Protein Stress in Neurodegenerative Disease – Sometimes Good, Sometimes Bad and Always UglyFriday, Mar 14, 2008
Research has shown that cells have a cleanup system for handling protein "stress," and some studies suggest the possibility
of developing therapeutic drugs that would work by giving the system a boost. But a new study published in Neuron suggests
that during prolonged stress, the cleanup system can suppress vital cell functions or even actively kill the cell.
Leptin Inhibits Seizures; Study May Lead to New Treatments for EpilepsyThursday, Mar 13, 2008
A new study shows that leptin, a hormone normally associated with eating and metabolism, can inhibit seizures in animal models
of epilepsy. The finding may lead to new ways of treating epilepsy. It also may help explain how the ketogenic diet, which
is sometimes used to treat epilepsy, reduces seizures.
An Over-Worked, Under-Appreciated Brain Cell Finally Gets its DueTuesday, Mar 11, 2008
As the cells that generate the brain's electrical signals, neurons tend to grab the limelight when it comes to studies of
brain function. Until recently, brain cells called glia have been mostly ignored, and their roles remain poorly understood,
despite the fact that they outnumber neurons by about 10 to 1.
