Motorcycle helmets, long known to dramatically reduce the number of brain injuries and deaths from crashes, appear to also be associated with a lower risk of cervical spine injury, new research from Johns Hopkins suggests.
Scratching deep beneath the surface, a team of researchers from the University of California, San Diego School of Medicine and three South Korean institutions have identified two distinct neuronal signaling pathways activated by a topical cream used to treat a variety of skin diseases. One pathway produces the therapeutic benefit; the other induces severe itching as a side effect.
Researchers at the University of Utah’s Comprehensive Arrhythmia and Research Management (CARMA) Center have found that delayed-enhancement magnetic resonance imaging (DE-MRI) holds promise for predicting the risks of strokes, the third leading cause of death in the U.S.
Like listeners adjusting a high-tech radio, scientists at Washington University School of Medicine in St. Louis have tuned in to precise frequencies of brain activity to unleash new insights into how the brain works.
People who spend more time in the sun and those with higher vitamin D levels may be less likely to develop multiple sclerosis (MS), according to a study published in the February 8, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology. MS is a chronic disease of the brain and spinal cord, usually with recurrent flare-ups of symptoms. It is often preceded by a first episode (or event) of similar symptoms lasting days to weeks.
When a laboratory rat learns how to reach for and grab a food pellet – a pretty complex and unnatural act for a rodent – the acquired knowledge significantly alters the structure of the specific brain cells involved, which sprout a whopping 22 percent more dendritic spines connecting them to other motor neurons.
Older people with larger waistlines, high blood pressure and other risk factors that make up metabolic syndrome may be at a higher risk for memory loss, according to a study published in the February 2, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A simple test performed at the sideline of sporting events can accurately detect concussions in athletes, according to study by researchers at the University of Pennsylvania School of Medicine.
Surgery to "deactivate" migraine headaches produces lasting good results, with nearly 90 percent of patients having at least partial relief at five years' follow-up, reports a study in the February issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Registration is now open to journalists planning to attend the 63rd Annual Meeting of the American Academy of Neurology (AAN) in Hawaii, April 9–16, 2011. The AAN Annual Meeting is the world’s largest gathering of neurologists who come together to share the latest advances in neurologic research.
Philip Schatz Ph.D., professor of psychology, and his associates recently published a study in Neurosurgery that identifies potentially enduring effects of multiple previous concussions on high school students. More specifically, Schatz and his colleagues propose through their research that teens with multiple concussions may already be demonstrating early signs of post-concussion syndrome.
Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, until now no one knew which purpose nestin serves in a cell.
Taxol® stabilizes growing nerve cells and reduces the barrier of scar tissue.
Researchers at the University of North Carolina at Chapel Hill have pinpointed a crucial function for a key player in the development of the nervous system.
Researchers from Mount Sinai School of Medicine have identified a therapy that may enhance memory and prevent the loss of long-term memory. The research is published in the January 27th issue of Nature.
New research from the University of North Carolina at Chapel Hill School of Medicine describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses.
An influential article in the journal Progress in Neurobiology provided one of the first comprehensive reviews of how estrogen potentially can protect against Alzheimer's disease and other neurological disorders.
Researchers have found the brain region responsible for allowing our brains to ignore background motion in favor of the motions of objects in the foreground. Interestingly, the elderly and people with schizophrenia and depression don't prioritize in this way.
In the wake of recent reports of long-term health effects of repeated concussions in professional athletes, a new study finds increased rates of concussion-related symptoms in high-school athletes with a history of two or more previous concussions. The study will appear in an upcoming issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health
As the population ages, neurologists will be challenged by a growing population of patients with stroke, dementia, Parkinson's disease and epilepsy.
