An advanced imaging technique has revealed that some U.S. military personnel with mild blast-related traumatic brain injuries have abnormalities in the brain that have not been seen with other types of imaging. The abnormalities were found in the brain's white matter, the wiring system that nerve cells in the brain use to communicate with each other. The study is reported June 2 in The New England Journal of Medicine by scientists at Washington University School of Medicine in St. Louis and...

In a study to be presented today at the Society for Maternal-Fetal Medicine's (SMFM) annual meeting, The Pregnancy Meeting â“ž¢, in San Francisco, researchers will present findings that showed that in rats, the use of magnesium sulfate (Mg) significantly reduced the neonatal brain injury associated with maternal inflammation or maternal infection. Magnesium sulfate is sometimes used during preterm labor to reduce the risk of neonatal brain injury. In 2010 the...

The human brain operates as a highly interconnected small-world network, not as a collection of discrete regions as previously believed, with important implications for why many of us experience cognitive declines in old age, a new study shows. Australian researchers have mapped the brain's neural networks and for the first time linked them with specific cognitive functions, such as information processing and language. Results from the study are published in the prestigious Journal of...

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...

The brains of fighter pilots are significantly different from those of the average individual, claims a new study published Tuesday in the Journal of Neuroscience. Using a series of cognitive tests and MRI scans, researchers from University College London (UCL) studied 11 front-line Tornado fighter pilots from the Royal Air Force (RAF). Each of the pilots were asked to complete two "cognitive control" tasks centered around rapid decision making, and also had their brains scanned using a type...

Magnetic resonance imaging (MRI) of the brain could expand the number of stroke patients eligible for a potentially life-saving treatment, according to a new study, published online and in the December issue of the journal Radiology. Some patients who suffer an acute ischemic stroke "” in which a blood clot or other obstruction blocks blood flow in the brain "” can be treated with a drug called tissue plasminogen activator, or tPA, that dissolves the clot and restores blood flow....

The most detailed magnetic resonance images ever obtained of a mammalian brain are now available to researchers in a free, online atlas of an ultra-high-resolution mouse brain, thanks to work at the Duke Center for In Vivo Microscopy. In a typical clinical MRI scan, each pixel in the image represents a cube of tissue, called a voxel, which is typically 1x1x3 millimeters. "The atlas images, however, are more than 300,000 times higher resolution than an MRI scan, with voxels that are 20...

Doctors should use a diffusion MRI scan to diagnose stroke instead of a CT scan, according to a new guideline from the American Academy of Neurology. The guideline is published in the July 13, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology. "While CT scans are currently the standard test used to diagnose stroke, the Academy's guideline found that MRI scans are better at detecting ischemic stroke damage compared to CT scans," said lead...


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.
