New model for speech and sound recognition People are adept at recognizing sensations such as sounds or smells, even when many stimuli appear simultaneously. But how the association works between the current event and memory is still poorly understood. Scientists at the Bernstein Center and the Ludwig-Maximilians Universität (LMU) München have developed a mathematical model that accurately mimics this process with little computational effort and may explain...

Research conducted by Boston College neuroscientist Sean MacEvoy and colleague Russell Epstein of the University of Pennsylvania finds evidence of a new way of considering how the brain processes and recognizes a person´s surroundings, according to a paper published in the latest issue of Nature Neuroscience. For the study, MacEvoy and Epstein used functional magnetic resonance image (fMRI) to help them identify how the brain figures out where it is in the world (scene recognition)....

New study pinpoints areas of the brain used exclusively for language, providing a partial answer to a longstanding debate in cognitive science New research from MIT suggests that there are parts of our brain dedicated to language and only language, a finding that marks a major advance in the search for brain regions specialized for sophisticated mental functions. Functional specificity, as it's known to cognitive scientists, refers to the idea that discrete parts of the brain handle...

A University of Colorado Boulder research team has developed a new software program allowing neuroscientists to produce single brain images pulled from hundreds of individual studies, trimming weeks and even months from what can be a tedious, time-consuming research process. The development of noninvasive neuroimaging techniques such as functional magnetic resonance imaging, or fMRI, spurred a huge amount of scientific research and led to substantial advances in the understanding of the human...

Study highlights the importance of cognitive skills in exercising control over addictive drugs A study, completed by researchers from Trinity College and the Research Institute for a Tobacco Free Society, Dublin, Ireland, compares former smokers to current smokers, and obtains insight into how to quit smoking might be discovered by studying the brains of those who have successfully managed to do so. Functional MRI images were obtained while current smokers, former smokers and never smokers...

An international team of scientists has developed a way to predict how much a person can learn, based on studies at UC Santa Barbara's Brain Imaging Center. A study published in this week's Proceedings of the National Academy of Sciences (PNAS) details the findings. Researchers collected brain imaging data from people performing a motor task, and then analyzed this data using new computational techniques. They found evidence that the flexibility of a person's brain can be used to predict how...

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...

Predictability can improve multitasking Researchers from Rice University and Georgia Institute of Technology have found support for the theory that the brain has three concentric layers of working memory where it stores readily available items. Memory researchers have long debated whether there are two or three layers and what the capacity and function of each layer is. In a paper in the March issue of the Journal of Cognitive Psychology, researchers found that short-term memory is made...

Although it is quite common for a brief, unique experience to become part of our long-term memory, the underlying brain mechanisms associated with this type of learning are not well understood. Now, a new brain-imaging study looks at the neural activity associated with a specific type of rapid learning, insight. The research, published by Cell Press in the March 10 issue of the journal Neuron, reveals specific brain activity that occurs during an "A-ha!" moment that may help encode the new...

Study finds crowdsourced articles compare favorably to those by single authors Writing can be a solitary, intellectual pursuit, but researchers at Carnegie Mellon University have shown that the task of writing an informational article also can be accomplished by dozens of people working independently online. Each person in the CMU experiments completed just a sliver of the work of preparing an article, such as preparing an outline, gathering facts or assembling facts into simple prose. The...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
