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.

Melatonin, taken orally can improve ability to sleep

Researchers from the Divisions of Sleep Medicine at Brigham and Women's Hospital and Harvard Medical School have found in a double-blind placebo-controlled clinical study, that melatonin, taken orally during non-typical sleep times, significantly improves an individual's ability to sleep.

Study helps explain why aerobic training helps heart failure patients

Aerobic training is associated with a reversal of abnormal hormonal patterns that underlie many of the debilitating symptoms of heart failure, according to a new study in the Journal of the American College of Cardiology.

Obtaining and documenting informed patient consent prior to surgery

Obtaining and documenting informed patient consent prior to surgery is of vital importance, but both the process and documentation of consent can be inadequate.

Varenicline could increase number who quit smoking

Smokers who try to quit using existing medications, such as nicotine patches or Zyban, are about twice as likely to succeed as those who don't use medication or are prescribed placebos during clinical trials.

Very young infants are much more capable of organising their visual world than previously thought

Research investigating attention in infancy has revealed that, at just four months old, babies are able to organise visual information in at least three different ways, according to brightness, shape, and how close the visual elements are together (proximity).

Virtual reality simulation technology improves carotid angiography skills

Cardiologists can learn to perform risky catheter procedures such as carotid angiography on a virtual patient simulator, rather than on real patients, according to a new study in the May 2, 2006, issue of the Journal of the American College of Cardiology.

Inflammation markers identify fatigue in breast cancer survivors

Researchers at the University of California, Los Angeles have defined conditions associated with disabling fatigue that persists for years in almost a third of breast cancer survivors, according to a study in the May 1 issue of Clinical Cancer Research.

An engineered virus that tracks down and compels cancer cells to eat themselves

An engineered virus tracks down and infects the most common and deadly form of brain cancer and then kills tumor cells by forcing them to devour themselves, researchers at The University of Texas M. D. Anderson Cancer Center report.

New study describes molecular basis of NeuroAIDS

Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus.

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.

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.

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.
