The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Defects in mitochondria lead to devastating neurodegenerative disease

A devastating neurodegenerative disease that first appears in toddlers just as they are beginning to walk has been traced to defects in mitochondria, the 'batteries' or energy-producing power plants of cells. This finding by a team of researchers, led by investigators from the Montreal Neurological Institute and Hospital - The Neuro- at McGill University, was published in this week's issue of the Proceedings of the National Academy of Sciences of the USA.

Insights into rates and impact of mTBI among military personnel in Iraq/Afghanistan

As the last U.S. troops return home from Iraq, new research lends timely insights into the rates and impact of mild traumatic brain injury (mTBI) among military personnel serving in Iraq/Afghanistan, according to a topical issue of The Journal of Head Trauma Rehabilitation (JHTR), the official journal of the Brain Injury Association of America.

Neuronal energy deficits may contribute to amyotrophic lateral sclerosis

Turning off a protein that helps cells balance energy increases animal mobility and reduces the death of nerve cells that control movement in animal models of amyotrophic lateral sclerosis (ALS), according to a study in the January 18 issue of The Journal of Neuroscience. The findings may one day guide new directions for the treatment of the progressive neurodegenerative disorder, for which there is currently no cure.

Study shows how to stop brain cancer cell proliferation and migration

Brain cancer is hard to treat: it's not only strong enough to resist most chemotherapies, but also nimble enough to migrate away from radiation or surgery to regrow elsewhere. New research at the University of Colorado Cancer Center shows how to stop both.

Connection between Musashi1 and HuR proteins can lead to glioblastoma

Most research on glioblastoma development, a complicated tumor of the brain with a poor prognosis, has focused on the gene transcription level, but scientists suggest that post-transcriptional regulation could be equally or even more important.

Research aims to develop physiologically-inspired algorithms

New research is hoping to understand how the human brain hears sound to help develop improved hearing aids and automatic speech recognition systems.

Sleep strongly 'protects' negative emotional response

A recent study by sleep researchers at the University of Massachusetts Amherst is the first to suggest that a person's emotional response after witnessing an unsettling picture or traumatic event is greatly reduced if the person stays awake afterward, and that sleep strongly "protects" the negative emotional response.

Immobilization of one hand causes rearrangement of brain matter

What happens in the brain of right-handed people if their dominant hand is immobile for two weeks? This is the question addressed in the latest study led by Professor Lutz J-ncke and the Trauma Surgery Department at Zurich University Hospital.

Novelos initiates enrollment in HOT Phase 1b trial for advanced solid tumors

Novelos Therapeutics, Inc., a pharmaceutical company developing novel drugs for treatment and diagnosis of cancer, today announced that it has enrolled the first patient in a U.S. multi-center Phase 1b dose-escalation trial of its cancer-targeted molecular radiotherapeutic compound (131)I-CLR1404 (HOT) in cancer patients with advanced solid tumors.

Vitamin D supplements can fight against age-related macular degeneration

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have found that vitamin D reduces the effects of ageing in mouse eyes and improves the vision of older mice significantly. The researchers hope that this might mean that vitamin D supplements could provide a simple and effective way to combat age-related eye diseases, such as macular degeneration (AMD), in people.

Researchers discover gene that causes benign familial infantile epilepsy

A team of Australian researchers has come a step closer to unlocking a mystery that causes epileptic seizures in babies.

AAN neurologist receives prestigious award at Palatucci Advocacy Leadership Forum

The American Academy of Neurology(AAN) has named neurologist Constantine Moschonas, MD, of Scottsdale, Ariz., as the AAN Donald M. Palatucci Advocacy Leadership Forum Advocate of the Year. Moschonas received his award at the Palatucci Advocacy Leadership Forum on January 14, 2012, in Austin, Texas, for his outstanding work in raising awareness about brain diseases such as Alzheimer's disease, stroke, autism, Parkinson's disease and multiple sclerosis.

Alcohol-dependent Americans more likely to seek treatment than South Koreans

Hazardous alcohol use and depression are among the 10 leading causes of disability and premature death worldwide, according to the World Health Organization. Many low- to middle-income countries have begun to see a steady increase in alcohol use and have entered the early stages of a tobacco epidemic. A study of alcohol use disorders (AUDs), nicotine dependence (ND), and mood and anxiety disorders in the United States and South Korea has found that while AUDs are substantially more common among Americans than South Koreans, alcohol-dependent Americans are significantly more likely to seek treatment.

Arm sling or cast use after injury may cause rapid brain shift

Using a sling or cast after injuring an arm may cause your brain to shift quickly to adjust, according to a study published in the January 17, 2012, print issue of Neurology-, the medical journal of the American Academy of Neurology.

Older adults with dementia can benefit from exergames

Virtual reality-enhanced exercise, or "exergames," combining physical exercise with computer-simulated environments and interactive videogame features, can yield a greater cognitive benefit for older adults than traditional exercise alone, according to a new study published in the February issue of the American Journal of Preventive Medicine.

Angioplasty improves quality of life in MS patients

Although using angioplasty to treat multiple sclerosis (MS) is highly controversial, sufferers often insist it helps - in some cases dramatically, such as allowing them to walk without a cane. Patients with less severe MS also reported additional quality of life improvements, such as being able to talk more clearly, after having treatment to open blocked blood vessels in the chest and neck, according to research being presented at the 24th annual International Symposium on Endovascular Therapy.

Study compares brain activity of FHP youth to peers with no family history of alcoholism

Researchers know that adolescents with a family history of alcoholism (FHP) are at risk for developing alcohol use disorders. Some studies have shown that, compared to their peers, FHP adolescents have deficits in behavioral inhibition.

Pedestrian injuries and deaths from headphone use on the rise

Listen up, pedestrians wearing headphones. Can you hear the trains or cars around you? Many probably can't, especially young adult males. Serious injuries to pedestrians listening to headphones have more than tripled in six years, according to new research from the University of Maryland School of Medicine and the University of Maryland Medical Center in Baltimore.

Scientists discover novel mechanism to prevent cell death of nerve cells

Oxygen and glucose are the food of our brain. If they are absent, such as during a stroke, nerve cells die. An international research team at Charité - Universitätsmedizin Berlin, Germany, and McMaster University, Canada, has discovered a novel mechanism to prevent this cell death. The results of the study have now been published in the journal Proceedings of the National Academy of Sciences of the USA.
