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.

Identification of CPT1c gene that the brain needs to manage body weight

Working with genetically engineered mice, Johns Hopkins scientists have interfered with the brain's ability to control an animal's response to a high-fat diet.

Combined pharmacotherapies and behavioral interventions for alcohol dependence

While many treatment approaches were found helpful, the authors report that the patients who were most successful in abstaining from alcohol 16 weeks after treatment were those prescribed naltrexone under medical management and those participating in a multi-session program of alcohol counseling delivered by a behavioral specialist.

Epstein-Barr virus may trigger multiple sclerosis

Researchers have found that patients with multiple sclerosis (MS) carry a population of immune cells that overreact to Epstein-Barr virus.

Potentially powerful tool for designing novel Alzheimer's treatments

Researchers have identified a protein that reins in the rogue activity of the molecules that make the amyloid-beta protein--which may prevent normal brain function in people with Alzheimer's disease. Their findings reveal a potentially powerful tool for designing novel Alzheimer's treatments.

Possible target for future therapies aimed at delaying or stopping Alzheimer's disease

Researchers at Oregon Health & Science University's Neurological Sciences Institute (NSI) have located a possible target for future therapies aimed at delaying or stopping Alzheimer's disease.

Kidney patients warned away from potassium

Many kidney failure patients are increasing their chance of nerve damage in their legs and feet by simply having too much potassium in their diet, according to research carried out by the University of New South Wales (UNSW), the Prince of Wales Medical Research Institute (POWMRI) and the Prince of Wales Hospital.

Sperm-producing stem cells found in testicles could be extracted, grown in the lab, and frozen for future use

Men may cringe at the idea, but sperm-producing stem cells found in testicles could be extracted, grown in the lab, and frozen for future use.

Blood clots in the brain linked to Alzheimer's and dementia

According to researchers, from the University of Manchester, UK, spontaneous blood clots are significantly associated with both Alzheimer's disease and vascular dementia.

New method found showing how nerve cells can selectively filter and transfer signals

Scientists from Gvttingen and Bochum find evidence for a new mechanism, with which our nerve cells are able to filter signals and transfer them selectively.

Human brain observed to shut down 'self'

Everybody has experienced a sense of "losing oneself" in an activity--whether a movie, sport, sex, or meditation. Now, researchers have caught the brain in the act of losing "self" as it shuts down introspection during a demanding sensory task. New findings show that self-related function actually shuts down during such intense sensory tasks.

New theory on how the brain detects motion

Researchers at the Salk Institute for Biological Studies have discovered a neural circuit that is likely to play an important role in the visual perception of moving objects. Their finding, published in the April issue of the journal Neuron, forces neurobiologists to rethink the neural pathways that our brain relies on to detect motion.

Tumour specific drugs may render therapies based on a tumor's anatomical location obsolete

The results of a new study at Washington University School of Medicine in St. Louis could eventually have oncologists removing their specialties from their shingles by making therapy based on a tumor's anatomical location obsolete.

Amyloid protein content in the brain linked to Alzheimer's disease risk

Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp are the first to show that the quantity of amyloid protein in brain cells is a major risk factor for Alzheimer's disease. Amyloid protein has already been known to be the primary component of the senile plaques in the brains of patients. The new discovery demonstrates that the greater the quantity of the protein that is produced, the younger the dementia patient is.

Economic benefit of federally finded clinical trials exceeds $15 billion

A comprehensive review of all phase III clinical trials supported by one Federal agency finds that, estimated conservatively, the economic benefit in the United States from just eight of these trials exceeded $15 billion over the course of 10 years. The study also found that new discoveries from the trials were responsible for an estimated additional 470,000 healthy years of life. The clinical trials were sponsored by the National Institutes of Health's National Institute of Neurological Disorders and Stroke (NINDS).

Researchers figure out how nuclear pores duplicate before cells divide

Researchers have long wondered how nuclear pores - the all-important channels that control the flow of information in and out of a cell's nucleus - double in number to prepare for the split to come when a cell divides. Now, for the first time, scientists at the Salk Institute for Biological Studies watched as new funnel-like pore structures formed from scratch, and inserted themselves into the nuclear membrane.

Osteoporosis could be caused by factors other than declining estrogen levels

New evidence in the April 21, 2006 Cell challenges the long-standing notion that declining estrogen levels alone lead to osteoporosis after women go through menopause. The researchers rather found that high levels of pituitary-derived follicle-stimulating hormone (FSH) cause bone loss in mice. The pituitary is a master gland found at the base of the brain.

Friends and family can protect against Alzheimer's disease

Having close friends and staying in contact with family members offers a protective effect against the damaging effects of Alzheimer's disease according to research by physicians at Rush University Medical Center in Chicago. The study, which is currently posted online in The Lancet Neurology, will be published in the May print edition of the journal.

Researchers identify characteristics that may lead to alcoholism

Those who are male and have behavioral disinhibition have the highest risk of developing alcoholism. Also, individuals with a family history of alcoholism (FH+) have a greater risk of developing alcoholism themselves than do persons with no family history, while FH+ individuals who are male and have behavioral disinhibition may have the greatest risk of developing alcoholism. Researchers caution that these combined characteristics indicate a greater probability, not certainty, of developing alcoholism.
