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...

The Stripe of Gennari develops even in those who are blind from birth and does not degenerate, despite a lack of visual input. This was discovered by Robert Trampel and colleagues from the Max Planck Institute for Human Cognitive and Brain Sciences using magnetic resonance imaging. This bundle of nerve fibers, which is approximately 0.3 mm thick, is not exclusively responsible for optic information. In the blind, it might play a greater role in processing tactile stimuli. This could...

According to University of Toronto speech-language pathologist Luc De Nil, the beat could be revealing such things as how children master one of the most complex tasks of all "“ speech. "The rapid and precise muscle movements of speech must be the most intricate, yet poorly understood, of all the sensory-motor skills," says De Nil. De Nil's interest in finger-tapping came out of his group's previous work on adults who stutter. His team discovered that they have problems in acquiring new...

New findings reported this week in Science by researchers at the RIKEN Brain Science Institute (BSI) shed first-ever light on the neural mechanisms that enable board game experts to quickly generate optimal moves. Results identify specific brain regions involved in granting shogi masters their superior skill, offering insights into the neural origins of expert intuition. (PRWeb UK) January 20, 2011 What makes experts different from the rest of us? Over the past century, this question has...

The combined results of a genetic blood test and a five-minute functional MRI successfully classified more than three-quarters of healthy older adults, many of whom were destined to develop cognitive decline within 18 months of testing. John Woodard, Ph.D., associate professor of psychology in the College of Liberal Arts and Sciences and Institute of Gerontology at Wayne State University, is lead author of "Predicting Cognitive Decline in Healthy Older Adults Using fMRI" published in the...

Over the last few years, researchers have used a type of brain scanning, known as functional magnetic resonance imaging fMRI, to help them map changes in blood flow in the brain and to correlate this with thoughts and behavior. A new way to analyze fMRI data, which could improve is reported in the International Journal of Computational Biology and Drug Design. Scientists have known since the 1890s that changes in blood flow and blood oxygenation in the brain (hemodynamics) are correlated with...

Watching the brain's "autopilot" network in real time may help determine the onset of cognitive decline and potentially aid in making an early diagnosis of Alzheimer's disease, according to researchers at Duke University Medical Center. While traditional MRI and imaging studies conducted in Alzheimer's disease have focused on the anatomy and function of individual regions of the brain, the Duke team conducted the first study to test how the integrity of an entire brain network relates to...

2 acceleration methods make scanning more than 7 times faster An international team of physicists and neuroscientists has reported a breakthrough in magnetic resonance imaging that allows brain scans more than seven times faster than currently possible. In a paper that appeared Dec. 20 in the journal PLoS ONE, a University of California, Berkeley, physicist and colleagues from the University of Minnesota and Oxford University in the United Kingdom describe two improvements that allow full...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
