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.

Electroacupuncture can lower blood pressure

Dr. John C. Longhurst, director of the Susan Samueli Centre for Integrative Medicine at UC Irvine ,and researchers, have found that acupuncture using low levels of electrical stimulation can lower elevations in blood pressure by as much as 50 percent.

Solving sleep problems helps epileptic children

Sleeping woes may explain why children with epilepsy are often so hyperactive, say researchers with the University of Florida's Evelyn F. and William L. McKnight Brain Institute.

Medication that both stimulates appetite and reduces metabolic rate

Scientists at Oregon Health & Science University, in collaboration with Neurocrine Biosciences Inc., have successfully tested a research medication that both stimulates appetite and reduces metabolic rate in preclinical trials.

Finding opens new doors to determining susceptibility to antidepressant side effects

In a finding that opens new doors to determining susceptibility to antidepressant side effects, researchers at the UCLA Neuropsychiatric Institute report that changes in brain activity prior to treatment with antidepressants can flag patient vulnerability.

Device may offer alternative for stroke patients

As the most common cause of adult disability in the United States, stroke leaves many survivors unable to perform tasks that were once part of their daily routine. Much of the time the disabilities are treatable, but the high cost of rehabilitation therapy leaves many patients to cope on their own.

Clinical study of mirror neurons provides insights into autism and other disorders

Seeing is doing – at least it is when mirror neurons are working normally. But in autistic individuals, say researchers from the University of California, San Diego, the brain circuits that enable people to perceive and understand the actions of others do not behave in the usual way.

Left-right brain mystery - trail is hot and cold

Australian National University (ANU) researchers have developed a new device that could potentially unravel the mysteries of the left and right brain by measuring ear temperature.

Vaccine prevents deadly pneumonia in African children

Global health leaders today presented new research showing that vaccinating infants against Streptococcus pneumoniae -- a bacterium that causes deadly pneumonia, meningitis and sepsis -- could substantially reduce death and serious illness among children in the developing world. If used widely, a pneumococcal conjugate vaccine could prevent hundreds of thousands of child deaths each year.

Poor survival rates in some cancers related to lack of clinical trial participation

In a new study Archie Bleyer, M.D. of the M. D. Anderson Cancer Centre in Houston and colleagues have discovered that mortality and poor survival rates among young adults and older adolescents with some cancers may be explained in part by the lack of participation in clinical trials.

Diffusion MRI gives early indication if brain cancer therapy is effective

A special type of MRI scan that measures the flow of water molecules through the brain can help doctors determine early in the course of brain cancer regimen if a patient's tumor will shrink, a new study shows.

Invisible influences reveal unconscious pathways used in visual perception

Our conscious awareness is underpinned by activity in our brain, but there is far more going on in our brain at any one time than we can possibly be aware of. So what aspects of our brain's activity are we actually aware of?

Gene variations explain drug dose required to control seizures

Determining which variants of particular genes patients with epilepsy carry might enable doctors to better predict the dose of drugs necessary to control their seizures, suggest basic findings by researchers at the Duke University Institute for Genome Sciences & Policy (IGSP) and the University College London.

Tool reliably predicts recovery from coma

A Department of Veterans Affairs and Northwestern University researcher has developed the first reliable measure of neurobehavioral functioning that will help physicians predict the likelihood of a patient recovering consciousness during coma from severe brain injury within the first year of injury--with up to 86 percent certainty.

Researchers have identified the proteins that allow specific brain cells to "change channels"

Johns Hopkins researchers have identified the proteins that allow specific brain cells to "change channels," a rare ability that tweaks what can come into the cell. The findings, described in the March 24 issue of Neuron, might let researchers harness the process, perhaps one day using it to protect cells that die in Lou Gehrig's disease.

Molecule that causes secondary stroke

Scientists at the University of Cincinnati (UC) College of Medicine have discovered the cause of a deadly type of secondary stroke known as cerebral vasospasm.

Fish is brain food

Researchers with the Department of Veterans Affairs (VA) and the University of California at Los Angeles (UCLA) found that a diet high in docosahexenoic acid, or DHA--an omega-3 fatty acid found in relatively high concentrations in cold-water fish--dramatically slowed the progression of Alzheimer's disease in mice.

US Court rejects appeal of Terri Schiavo's parents

The full 11th U.S. Circuit Court of Appeals in Atlanta has denied the request by Terri Schiavo's parents that doctors be ordered to reinsert the feeding tube that has kept their brain-damaged daughter alive for 15 years.

New directions toward the treatment of bipolar disorder

While lithium treatment has proven to be a godsend for many of the two million Americans with bipolar disorder, it is not without its downside. People on the drug may develop hypothyroidism, tremors, cognitive impairment, and excessive thirst and urination and gain weight.

Evidence of cross-activation in brain regions of people who see letters and numbers in colors

Synesthesia, a condition characterized by one sensory experience generating another – so that shapes have tastes, for instance – is estimated to affect between 1 in 200 to 1 in 2,000 people. The most common form involves seeing specific letters or numbers (graphemes) in specific colors.
