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.

Scientists identify molecular mechanism behind alcohol-induced blackouts

A person who drinks too much alcohol may be able to perform complicated tasks, such as dancing, carrying on a conversation or even driving a car, but later have no memory of those escapades. These periods of amnesia, commonly known as "blackouts," can last from a few minutes to several hours.

Study: Breastfeeding does not appear to protect women from MS relapses

New research finds breastfeeding doesn't appear to protect against multiple sclerosis (MS) relapses, despite previous studies suggesting there may be a protective role. The research is published in the July 6, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.

Understanding glioblastoma at the genetic, molecular level

Glioblastoma is the most common and most lethal form of brain tumor in people. Research published in the International Journal of Computational Biology and Drug Design offers a novel way to determine what biological functions go awry when the tumor first begins to form.

Freeze-dried gene therapy system safe and effective for treating brain cancer

Researchers at the Johns Hopkins University School of Medicine have developed a technique that delivers gene therapy into human brain cancer cells using nanoparticles that can be freeze-dried and stored for up to three months prior to use. The shelf-stable particles may obviate the need for virus-mediated gene therapy, which has been associated with safety concerns.

Maternal smoking cessation improves perinatal outcomes in children

Low birthweight is the most common negative outcome of smoking during pregnancy, but foetuses exposed to maternal smoking are also at risk of premature birth and the associated problem of brain damage, as well as congenital abnormalities such as cleft lip.

Natural vitamin E may reduce brain damage after stroke

Ten weeks of preventive supplementation with a natural form of vitamin E called tocotrienol in dogs that later had strokes reduced overall brain tissue damage, prevented loss of neural connections and helped sustain blood flow in the animals' brains, a new study shows.

Neurochemical-producing probiotics can promote healthy gut and mind

Probiotics, often referred to as 'good bacteria', are known to promote a healthy gut, but can they promote a healthy mind? Exploring the new world of neurological probiotics, researchers in BioEssays present new ideas on how neurochemicals delivered directly to the gut, via probiotic intestinal microbiota, exert their beneficial effects in maintaining gastrointestinal health and even psychological well-being.

Alpha-tocotrienol protects brain cells after stroke in three ways

A natural form of vitamin E called alpha-tocotrienol can trigger production of a protein in the brain that clears toxins from nerve cells, preventing those cells from dying after a stroke, new research shows.

Human beings can control and intentionally forget unwanted memories

The assumption that we human beings can control and intentionally forget unwanted memories has been controversial ever since Freud asserted it at the beginning of the 20th century.

LCMC finds 9.6% of lung cancer patients with ALK rearrangement

ALK rearrangement has been found in 9.6% of lung cancer patients tested in the Lung Cancer Mutation Consortium, and MET amplification in another 4.1%, reflecting how many patients might benefit from targeted therapies such as crizotinib, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer.

Study helps explain why fatty foods are complicit in weight gain

Recent studies have revealed potato chips and french fries to be the worst contributors to weight gain - and with good reason. Have you ever wondered why you can't eat just one chip or a single fry? It's not just the carbohydrates at fault.

Study finds two reasons behind racial disparities in stroke treatment care

African-Americans are less likely than whites to receive critical stroke treatment primarily because they do not get to a hospital soon enough for time-sensitive treatment and because of preexisting medical conditions. For patients who are eligible for treatment, no racial disparity was found.
