Brain imaging reveals breakdown of normal emotional processing
08-16-2007 · EurekAlert!Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. Efforts by depressed patients to suppress their feelings when viewing emotionally negative images enhanced activity in several brain areas, including the amygdala, known to play a role in generating emotion, according to a report in the Aug. 15 issue of the Journal of Neuroscience.

- Distorted self-image due to visual brain glitch, UCLA research finds
12-03-2007 · EurekAlert!
Although they look normal, people suffering from body dysmorphic disorder perceive themselves as ugly and disfigured. New imaging research reveals that the brains of people with BDD look normal, but function abnormally when processing visual details. Reported in the December edition of the Archives of General Psychiatry, the UCLA findings are the first to demonstrate a biological reason for patients' distorted body image.

- NIDA research reveals subconscious signals can trigger drug craving
01-29-2008 · EurekAlert!
Using a brain imaging technology called functional magnetic resonance imaging, scientists have discovered that cocaine-related images trigger the emotional centers of the brains of patients addicted to drugs -- even when the subjects are unaware they've seen anything. The study, published Jan. 30 in the journal PLoS ONE, was funded by the National Institute on Drug Abuse, part of the National Institutes of Health.

- Alcoholics show deficits in their ability to perceive dangerous situations
08-27-2007 · EurekAlert!
Previous brain-imaging studies have suggested cognitive deficits in alcoholic patients. New findings indicate that alcoholic patients show emotional processing deficits as well.These deficits primarily affect processing for negative emotional expressions.

- Sleep-deprivation causes an emotional brain 'disconnect'
10-22-2007 · EurekAlert!
Without sleep, the emotional centers of the brain dramatically overreact to negative experiences, reveals a new brain imaging study in the Oct. 23 issue of Current Biology, a publication of Cell Press. The reason for that hyperactive emotional response in sleep-deprived people stems from a shutdown of the prefrontal lobe -- a region that normally keeps emotions under control.

05-21-2007 · EurekAlert!
A new UCLA imaging study reveals how inhaling 100 percent oxygen can harm the brain. The findings fly in the face of national guidelines for resuscitation and urge a new approach adding carbon dioxide to the gas mix to preserve brain function in patients.

- Obesity research boosted by watching hunger in the brain
11-07-2007 · EurekAlert!
Scientists can now measure how full or hungry a mouse feels, thanks to a new technique which uses imaging to reveal how neurons behave in the part of the brain which regulates appetite. Researchers hope the technique, which uses magnetic resonance imaging, will enable a far greater understanding of why certain people become obese when others do not, and why different people have different appetites.

- Imaging study reveals rapid formation of Alzheimer's-associated plaques
02-06-2008 · EurekAlert!
The amyloid plaques found in the brains of Alzheimer's disease patients may form much more rapidly than previously expected. Using an advanced microscopic imaging technique to examine brain tissue in mouse models of the devastating neurological disorder, researchers from the MassGeneral Institute for Neurodegenerative Disease find that plaques can develop in as little as a day and that Alzheimer's-associated neuronal changes appear soon afterwards.

- Gene tests and brain imaging reveal early dementia
03-06-2007 · EurekAlert!
Dementia diseases develop insidiously and are generally discovered when the memory has already started to deteriorate. New research form Swedish medical university Karolinska Institutet shows, however, that approaching Alzheimer's can be detected several years before the symptoms manifest themselves.
