Antibiotic that appears to control phobias may also be useful in treating addiction

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory provide further evidence that a drug known as D-cycloserine could play a role in helping to extinguish the craving behaviors associated with drug addiction.

64-slice CT scans a good test for clogged arteries

A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

Medical causes of iatrogenic renal disorders

Nephrologists and other health care providers need to be aware of certain medications and diagnostic test preparations that, in some patients, can cause damage to the kidneys, according to a special clinical update being presented at the American Society of Nephrology's 40th Annual Meeting and Scientific Exposition in San Francisco.

Heart plays a losing game of catch-up as people age

Researchers at Johns Hopkins have evidence to explain why the supposedly natural act of aging is by itself a very potent risk factor for life-threatening heart failure.

MRIs reveal 13% of healthy adults have a brain abnormality

A Dutch study has revealed that as many as 13% of healthy adults may have some type of undiagnosed abnormality in the brain.

PET scan distinguishes Alzheimer's from other dementia

A PET scan (positron emission tomography) that measures uptake of sugar in the brain significantly improves the accuracy of diagnosing a type of dementia often mistaken for Alzheimer's disease, a study led by a University of Utah dementia expert has found.

Harvard 'Brainbow' helps chart neural circuits

By activating multiple fluorescent proteins in neurons, neuroscientists at Harvard University are imaging the brain and nervous system as never before, rendering their cells in a riotous spray of colors dubbed a "Brainbow."

Sound training rewires dyslexic children's brains for reading

Some children with dyslexia struggle to read because their brains aren't properly wired to process fast-changing sounds, according to a brain-imaging study published this month in the journal Restorative Neurology and Neuroscience (online October 16).

Step toward mapping the human decision-making process

The brain, the human supercomputer, might work more like an assembly line when recognizing objects, with a hierarchy of brain regions separately absorbing and processing information before a person realizes what they are seeing, according to new research conducted at the University of Pittsburgh and published in the Oct. 31 edition of the Journal of Neuroscience.

New brain marker predicts cognitive decline and the development of Alzheimer's disease

Duke University Medical Center researchers have used imaging technology to identify a new marker that may help identify those at greatest risk for cognitive decline and the development of Alzheimer's disease.

New insights into how the brain takes in and assembles stimuli from the outside world

The area of the brain that processes sounds entering the ears also appears to process stimulus entering the eyes, providing a novel explanation for why many viewers believe that ventriloquists have thrown their voices to the mouths of their dummies.

New magnetic separation 'traveling wave magnetophoresis' might detect multiple pathogens at once

A magnetic separation technique developed by researchers at Duke University's Pratt School of Engineering and Purdue University makes it relatively simple to sort through beads hundreds of times smaller than the period at the end of this sentence.

New guideline recommends when to use CT scans in ER for seizures

A guideline developed by the American Academy of Neurology recommends immediate brain CT scans to screen certain emergency room patients with seizures.
