Weizmann Institute scientists reveal how some aromas are bound up in our memories From Proust's Madeleines to the overbearing food critic in the movie Ratatouille who's transported back to his childhood at the aroma of stew, artists have long been aware that some odors can spontaneously evoke strong memories. Scientists at the Weizmann Institute of Science have now revealed the scientific basis of this connection. Their research appeared in the latest issue of Current Biology. Graduate...

Common experience tells us that particular scents of childhood can leave quite an impression, for better or for worse. Now, researchers reporting the results of a brain imaging study online on November 5th in Current Biology, a Cell Press publication, show that first scents really do enjoy a "privileged" status in the brain. "We found that the first pairing or association between an object and a smell had a distinct signature in the brain," even in adults, said Yaara Yeshurun of the Weizmann...

A study published this week in PNAS provides a comprehensive comparative functional anatomy study in human and monkey brains which reveals highly similar brain networks preserved across evolution. An international collaboration co-led by scientists at NYU Langone Medical Center in New York City examined patterns of connectivity to show that the precuneus, long thought to be a single structure, is actually divided into four distinct functional regions. These areas were identified using...

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...
