You can teach an old dog new tricks, say UCLA scientists who found that middle-aged and older adults with little Internet experience were able to trigger key centers in the brain that control decision-making and complex reasoning after just one week of surfing the Web. The findings, presented Oct. 19 at the 2009 meeting of the Society for Neuroscience, suggest that Internet training can stimulate neural activation patterns and could potentially enhance brain function and cognition in older...

LONDON, Oct. 13 /PRNewswire/ -- Eastern Europe is poised to be the market to tap into in the near future for magnetic resonance imaging (MRI) manufacturers. These countries have budgets allocated to improve their healthcare systems after becoming members of the European Union (EU). Their installed base of MRI systems is not large, which directly makes this region conducive for market growth. At the same time, market prospects will receive a boost from an expanding application range....

Brain activity during event, failed recollection similar A woman looks familiar, but you can't remember her name or where you met her. New research by UC Irvine neuroscientists suggests the memory exists "“ you simply can't retrieve it. Using advanced brain imaging techniques, the scientists discovered that a person's brain activity while remembering an event is very similar to when it was first experienced, even if specifics can't be recalled. "If the details are still there, hopefully...

Finnish and Canadian scientists say they've found brain cells called astrocytes play a major role in generating functional magnetic resonance imaging signals. Professor Kai Kaila of the University of Helsinki and the Academy of Finland's Neuroscience Research Program, along with Professor Brian MacVicar of the University of British Columbia, found functional MRI imaging does not directly measure nerve cell activity. Instead, it actually measures changes in cerebrovascular circulation. Helping...

U.S. and Canadian scientists say the brains of adolescent girls who play the computer game Tetris appear to have greater thickness and efficiency. Researchers from the Mind Research Network, a non-profit organization in Albuquerque, and the Montreal Neurological Institute performed both structural and functional magnetic resonance imaging studies of the brains of girls who practiced the computer game Tetris for three months, and of girls who did not play the game. The scientists said the...

Brain imaging shows playing Tetris leads to a thicker cortex and may also increase brain efficiency, according to research published in the open access journal BMC Research Notes. A research team based in New Mexico is one of the first to investigate the effects of practice in the brain using two image techniques.Researchers from Mind Research Network in Albuquerque used brain imaging and Tetris to investigate whether practice makes the brain efficient because it increases gray matter. For 30...

Study is one of the first to investigate the effects of practice in the brain using two imaging techniques ALBUQUERQUE, N.M., Sept. 1 /PRNewswire-USNewswire/ -- Researchers at the Mind Research Network today announced the findings of a scientific study that used brain imaging and Tetris to investigate whether practice makes the brain efficient because it increases gray matter. Over a three-month period, adolescent girls practiced Tetris, a computer game requiring a combination of...

Functional magnetic resonance imaging (fMRI) is a technique widely used in studying the human brain. However, it has long been unclear exactly how fMRI signals are generated at brain cell level. This information is crucially important to interpreting these imaging signals. Scientists from the Academy of Finland's Neuroscience Research Programme (NEURO) have discovered that astrocytes, support cells in brain tissue, play a key role in the generation of fMRI signals.Functional magnetic imaging...

Sounds and images share a similar neural code in the human brain, according to a new Canadian study. In the online edition of the Proceedings of the National Academy of Sciences (PNAS), scientists from the Universit© de Montr©al and the Montreal Neurological Institute at McGill University explain how the same neural code in the brain allows people to distinguish between different types of sounds, such as speech and music, or different images.Participants were recruited to undergo...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
