PITTSBURGH, Jan. 13 /PRNewswire/ -- Two hundred years ago, archaeologists used the Rosetta Stone to understand the ancient Egyptian hieroglyphs. Now, a team of Carnegie Mellon University scientists has discovered the beginnings of a neural Rosetta Stone. By combining brain imaging and machine learning techniques, neuroscientists Marcel Just and Vladimir Cherkassky and computer scientists Tom Mitchell and Sandesh Aryal determined how the brain arranges noun representations.

Our vocabulary continues to grow and expand even in adulthood. Just ten years ago, the word 'blog' did not yet exist "“ and now we no longer remember when we heard this word for the first time or when we learned its meaning. At some stage new words become just as familiar to us as words we have learned earlier. One of the areas of interest in the Academy of Finland's Neuroscience Research Program (NEURO) is how the process of learning new words is reflected in the function of the...

Michael Frank, of the Brown Institute for Brain Science, has determined that variations of three different genes in the brain can predict whether individuals will make certain choices. His work,  in collaboration with colleagues at the University of Arizona, will be published in the August 2009 edition of Nature Neuroscience. Researchers at Brown University and the University of Arizona have determined that variations of three different genes in the brain (called single-nucleotide...

Training increases brain processing speed and improves our ability to multitask, new research from Vanderbilt University published in the June 15 issue of Neuron indicates. "We found that a key limitation to efficient multitasking is the speed with which our prefrontal cortex processes information, and that this speed can be drastically increased through training and practice," Paul E. Dux, a former research fellow at Vanderbilt, and now a faculty member at the University of Queensland in...

Your brain activity can reveal how you make big decisions, according to a new study. Researchers at Duke University Medical Center studied the brain as people handled a set of decision making problems and found brain regions associated with rational processing, such as the lateral prefrontal cortex, were most active when participants used a strategy not consistent with traditional rational choices. The findings also strongly argue against the commonly held the notion that there are rational...

Playing, and even watching, sports improves brain function Being an athlete or merely a fan improves language skills when it comes to discussing their sport because parts of the brain usually involved in playing sports are instead used to understand sport language, new research at the University of Chicago shows. The research was conducted on hockey players, fans, and people who'd never seen or played the game. It shows, for the first time, that a region of the brain usually associated with...
