(Ivanhoe Newswire) —Chewing fresh gum, thinking happy thoughts, taking deep breaths–they´re all ways we try and mentally distract ourselves from pain. New research shows there may be some truth behind these kooky pain-relieving tactics. The research is based on high-resolution spinal fMRI (functional magnetic resonance imaging). The findings showed as people experienced painful levels of heat, mental distractions actually inhibited the response to incoming pain signals at...

Mental distractions make pain easier to take, and those pain-relieving effects aren't just in your head, according to a report published online on May 17 in Current Biology, a Cell Press publication. The findings based on high-resolution spinal fMRI (functional magnetic resonance imaging) as people experienced painful levels of heat show that mental distractions actually inhibit the response to incoming pain signals at the earliest stage of central pain processing. "The results...

Disorders of consciousness such as coma or a vegetative state caused by severe brain injury are poorly understood and their diagnosis has relied mainly on patient responses and measures of brain activity. However, new functional and imaging-based diagnostic tests that measure communication and signaling between different brain regions may provide valuable information about the potential for consciousness in patients unable to communicate. These innovative approaches are described and compared...

Brain networks may avoid traffic jams at their busiest intersections by communicating on different frequencies, researchers at Washington University School of Medicine in St. Louis, the University Medical Center at Hamburg-Eppendorf and the University of Tübingen have learned. "Many neurological and psychiatric conditions are likely to involve problems with signaling in brain networks," says co-author Maurizio Corbetta, MD, the Norman J. Stupp Professor of Neurology at...

Dog Gone It -- What Are They Thinking?

Marshal Rosenthal for RedOrbit.com Researchers at Emory University think that the way to a dog´s heart is through its brain. At least, that´s what members of the research team -- Andrew Brooks, Gregory Burns and Mark Spivak -- postulate through a scanning procedure seeking to unlock the secrets our canine friends have been concealing for eons. The device used is a functional Magnetic Resonance Scanner (fMRI), more often found with humans inside than canines. Through the...

Brain scans of a small group of people can predict the actions of entire populations, according to a new study by researchers from the University of Michigan, the University of Oregon and the University of California at Los Angeles. The findings are relevant to political advertising, commercial market research and public health campaigns, and broaden the use of brain imaging from a diagnostic to a predictive tool. As opposed to the wisdom of the crowd, the study suggests that the...

Breakdown of white-matter pathways affects decision-making as we age If you are an aging baby boomer and you've noticed it's a bit harder to drive to unfamiliar locations or to pick a new brand of olive oil at the supermarket, you can blame it on the white matter in your brain. A brain-mapping study, published in the Apr. 11 issue of The Journal of Neuroscience, has found that people's ability to make decisions in novel situations decreases with age and is associated with a reduction in...

At a time when obesity has become epidemic in American society, Dartmouth scientists have found that functional magnetic resonance imaging (fMRI) brain scans may be able to predict weight gain. In a study published April 18, 2012, in The Journal of Neuroscience, the researchers demonstrated a connection between fMRI brain responses to appetite-driven cues and future behavior. "This is one of the first studies in brain imaging that uses the responses observed in the scanner to predict...

A network of brain regions which is activated during intense aesthetic experience overlaps with the brain network associated with inward contemplation and self-assessment, New York University researchers have found. Their study sheds new light on the nature of the aesthetic experience, which appears to integrate sensory and emotional reactions in a manner linked with their personal relevance. The study's co-authors were: Edward Vessel, a researcher in NYU's Center for Brain Imaging;...

Belkasoft develops a software toolkit, adapting commercially available brain activity analysis hardware for solving criminal cases. The new product, Belkasoft Mind Analyzer, enables the acquisition of human faces by capturing fMRI data generated by human brain cells. A dedicated facial recognition engine allows reliable identification of acquired faces against a pre-filled database, while the optional Identikit module allows building convincing facial composites. The tool runs in conjunction...
