Activation of the anterior cingulate cortex (ACC) has been associated with risk factors for alcohol use disorders in adolescents. A new study has used functional magnetic resonance imaging to examine ACC activity among adults. The increased ACC activation found during a working-memory task among alcohol-dependent participants may be an indicator of less control over alcohol-consuming behavior.

Imaging the Brain Better, Faster,Thinner
A lot of the studies that I cast my Neuroskeptical eye over are related to functional magnetic resonance imaging (fMRI).This is because, in my opinion, quite a lot of today's fMRI work suffers from methodological flaws. But that's not to say that all fMRI work is suspect, or, worse, that there's something inherently unscientific about fMRI as such. fMRI's a tool, an amazing one in a lot of ways,

Studying the brain with fMRI: Are researchers overstating their findings?
by Michael D. Anestis, M.S. Last week, PBB guest contributor Tracy Witte emailed me a link to an article that had appeared in Science News (click here for a link to the article). The topic was functional magnetic resonance imaging,...

For older adults, participating in social service activities can improve brain functions
Volunteer service, such as tutoring children, can help older adults delay or reverse declining brain function, according to a new study. Using functional magnetic resonance imaging (fMRI), the researchers found that seniors participating in a youth mentoring program made gains in key brain regions that support cognitive abilities important to planning and organizing one's daily life.

Men And Women May Respond Differently To Danger According To New Study
Researchers using functional magnetic resonance imaging (fMRI) to study brain activation have found that men and women respond differently to positive and negative stimuli, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

Functional MRI, Round 3: Six Items to Keep in Mind
This is the third and final installment in a series on biophysical mechanisms of functional magnetic resonance imaging (fMRI) technologies. My overarching goal has been to explain why great care must be exercised when interpreting data derived from these magnets. The inspiration for the series came as I was reading a magazine article while waiting for a plane to take off-my reaction to what I rea

Scientists Develop Novel Use Of Neurotechnology To Solve Classic Social Problem
Economists and neuroscientists have shown that they can use information obtained through functional magnetic resonance imaging measurements of whole-brain activity to create feasible, efficient, and fair solutions to one of the stickiest dilemmas in economics, the public-goods free-rider problem -- long thought to be unsolvable. This is one of the first-ever applications of neurotechnology to rea

Brain Defect Implicated In Early Schizophrenia
In the first functional magnetic resonance imaging study of its kind, neurologists and psychiatrists have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders. Activity in this specific region of the hippocampus may help predict the onset of the disease, offering opportunities for earlier diagnosis and for the development of drugs for sc
