Like a motorist who knows that the "check engine" light indicates something important but ill-defined is happening, neuroscientists have relied heavily on an incompletely understood technology called functional magnetic resonance imaging to show them what the brain is doing when people respond to different stimuli. The non-invasive technology offers a window into the physiology of human cognition and emotion, but "” without a satisfying explanation of how some common fMRI signals are...

By reading MRI scans, new software developed by Intel Corp. researchers has been able to correctly discern two words that a person has been thinking about nine out of 10 times, according to an Associated Press (AP) report published Thursday. According to AP writer Samantha Gross, "The software analyzes functional MRI scans to determine what parts of a person's brain is being activated as he or she thinks"¦ Eventually, the technology could help the severely physically disabled to...

Changes in brain connectivity with aging may enable older adults to remember positive events Milan, Italy -- Despite the aches and pains that occur in old age, many older adults maintain a positive outlook, remembering the positive experiences from their past. A new study, reported in the April 2010 issue of Elsevier's Cortex (http://www.elsevier.com/locate/cortex), reveals that older adults' ability to remember the past through a positive lens is linked to the way in which the brain...

Clinicians may be able to better predict the effects of strokes and other brain injuries by adapting a scanning approach originally developed for study of brain organization, neurologists at Washington University School of Medicine in St. Louis have found. The technique, known as resting-state functional connectivity (FC), reveals the health of brain networks that let multiple parts of the brain collaborate. Previous studies have shown that damage to these networks helps explain why damage to...

The more difficult the decision we face, the more likely we are not to act, according to new research by UCL scientists that examines the neural pathways involved in 'status quo bias' in the human brain. The study, published today in Proceedings of the National Academy of Sciences (PNAS), looked at the decision-making of participants taking part in a tennis 'line judgement' game while their brains were scanned using functional MRI (fMRI). First author Stephen Fleming, Wellcome Trust Centre...

It's no wonder attractive human faces are everywhere in media and advertising "“ when we see those faces, our brains are constantly computing how much the experiences are worth to us. New brain-imaging research shows it's even possible to predict how much people might be willing to pay for a particular face. Researchers at Duke University Medical Center found that as participants were watching a sequence of faces, their brains were simultaneously evaluating those faces in two distinct...

A study by British and Belgian researchers found that a man who had been presumed to be in a vegetative state for five years, can communicate "yes" and "no" using only his thought patterns, Reuters reported. The researchers said the man sustained a severe traumatic brain injury in a traffic accident in 2003. He remained physically unresponsive and was presumed to be in a vegetative state for five years. The study results, published in the authoritative New England Journal of Medicine, said...

A study using functional magnetic resonance imaging (fMRI) to evaluate brain function revealed that adults who were exposed to lead as children incur permanent brain injury. The results were presented today at the annual meeting of the Radiological Society of North America (RSNA). "What we have found is that no region of the brain is spared from lead exposure," said the study's lead author, Kim Cecil, Ph.D., imaging scientist at Cincinnati Children's Hospital Medical Center and professor of...

Sir Peter Mansfield, The University of Nottingham's Nobel Laureate for Physiology and Medicine, is to be recognized, once again, for his part in one of the most important breakthroughs in medical science. Sir Peter, who was co-inventor of magnetic resonance imaging (MRI), is to be presented with the Medical Research Council's (MRC) Millennium Medal at an awards ceremony at the Trent Building, The University of Nottingham on Monday November 30 2009. The MRC Millennium Medal recognizes an MRC...

TEL AVIV, Israel, November 30 /PRNewswire/ -- Optoacoustics has announced availability of the FOMRI-III(TM) dual channel microphone, the most advanced optical microphone available for use in functional magnetic resonance imaging (fMRI) environments. The third generation FOMRI represents a major step forward for fiber optic microphone technology, providing the clearest speech quality ever, with low-latency adaptive noise cancelling. The FOMRI-III also introduces the ability to...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
