New clues to the mystery of brain function, obtained through research by scientists at the Stanford University School of Medicine, suggest that distinct mental states can be distinguished based on unique patterns of activity in coordinated "networks" within the brain. These networks consist of brain regions that are synchronously communicating with one another. The Stanford team is using this network approach to develop diagnostic tests in Alzheimer's disease and other brain disorders in...

A UA study using economic models backed up by fMRI scans offers new insights on why people choose to cooperate rather than act selfishly; the study appears in the current issue of the neuroscience journal Neuron A team of researchers at the University of Arizona has brought a high-tech tool to bear on the study of a familiar and age-old emotion "“ guilt. What makes the investigation unique is the use of fMRI scans to target the regions of the brain associated with guilt. It also opens a...

A new study uses creative engineering to unravel brain mechanisms associated with one of the most fundamental subjective human feelings: self-consciousness. The research, published by Cell Press in the April 28 issue of the journal Neuron, identifies a brain region called the temporo-parietal junction (TPJ) as being critical for the feeling of being an entity localized at a particular position in space and for perceiving the world from this position and perspective. Recent theories of...

    * Alcohol dependence (AD) is strongly associated with impaired impulse control.    * A new study used functional magnetic resonance imaging to examine impulsive choices among people with a range of alcohol use disorders (AUDs).    * Findings suggest that impulsive choice in AD may be the result of functional anomalies in widely distributed but interconnected brain regions that are involved in cognitive and emotional control. Researchers...

As humans face increasing distractions in their personal and professional lives, University of British Columbia researchers have discovered that people can gain greater control over their thoughts with real-time brain feedback. The study is the world's first investigation of how real-time functional Magnetic Resonance Imaging (fMRI) feedback from the brain region responsible for higher-order thoughts, including introspection, affects our ability to control these thoughts. The researchers find...

(Ivanhoe Newswire) -- Physical pain and intense feelings of social rejection "hurt" in the same way, according to this study. The study shows that the same regions of the brain that become active in response to painful sensory experiences are activated during intense experiences of social rejection. "These results give new meaning to the idea that social rejection 'hurts'," University of Michigan social psychologist Ethan Kross, lead author of the study, was quoted as saying. "On the surface,...

Mathematical Sequence Strengthens fMRI Data, Penn Study Shows By combining sophisticated mathematical techniques more commonly used by spies instead of scientists with the power and versatility of functional magnetic resonance imaging (fMRI), a Penn neurologist has developed a new approach for studying the inner workings of the brain. A hidden pattern is encoded in the seemingly random order of things presented to a human subject, which the brain reveals when observed with fMRI. The research...

Scans with fMRI show areas in brain that change in response to emotions as children enter adolescence Just when children are faced with intensifying peer pressure to misbehave, regions of the brain are actually blossoming in a way that heighten the ability to resist risky behavior, report researchers at three West Coast institutions. The findings -- detailed in the March 10 issue of the journal Neuron -- may give parents a sigh of relief regarding their kids as they enter adolescence and pay...

Study uses fMRI scans to attempt communication with severely brain-injured patients, suggests cognitive functioning may not be recognized at bedside Using a sophisticated imaging test to probe for higher-level cognitive functioning in severely brain-injured patients provides a window into consciousness -- but the view it presents is one that is blurred in fascinating ways, say researchers at Weill Cornell Medical College in the Feb. 25 online edition of the journal Brain. In a novel study of...
