Mathematical value intuited without calculation; findings may impact math education Although fractions are thought to be a difficult mathematical concept to learn, the adult brain encodes them automatically without conscious thought, according to new research in the April 8 issue of The Journal of Neuroscience. The study shows that cells in the intraparietal sulcus (IPS) and the prefrontal cortex "” brain regions important for processing whole numbers "” are tuned to respond to...

This is an innovative view of the neurobiological mechanisms of cognitive control and opens up new lines of researchPsychologists and neurologists invest considerable effort in the study of working memory. In terms of information retention, there is a difference between long-term memory, which is affected in diseases such as Alzheimer, and short-term or working memory, which allows us to make immediate decisions or structure a discourse. This more ephemeral memory is affected in diseases such...

Working memory, which is our ability to retain and process information over short periods of time, is essential to most cognitive processes, such as thinking, language and planning. It has long been known that the working memory is subject to limitations, as we can only manage to "juggle" a certain number of mnemonic items at any one time. Functional magnetic resonance imagery (fMRI) has revealed that the frontal and parietal lobes are activated when a sequence of two pictures is to be...

Belgian researchers have developed a blood test that can predict a person's chances of developing dementia. Scientists at the Flanders Institute for Biotechnology have developed a test that can predict whether someone has an increased risk of frontal lobe dementia long before symptoms appear. Frontal lobe dementia (FTD) strikes people at an earlier age, occurring most frequently in patients younger than 65. The blood test concentrates on a shortage of the progranulin protein and is much more...

More than 40 percent of women ages 18-59 experience sexual dysfunction, with lack of sexual interest "” hypoactive sexual desire disorder, or HSDD "” being the most commonly reported complaint, according to medical researchers. While some question the validity of this diagnosis, a multidisciplinary team from the Stanford University School of Medicine is devoted to objective investigation of such problems. Here is a quick briefing on new research on this problem from Bruce Arnow,...

Brown University's David Badre, an assistant professor of cognitive and linguistic sciences, and colleagues at the University of California"“Berkeley mapped parts of the brain that control abstract or concrete decision making by studying stroke patients. Their findings will be published March 1 in the journal Nature Neuroscience. A Brown University study of stroke victims has produced evidence that the frontal lobe of the human brain controls decision-making along a continuum from...

We all know the feeling: a golden oldie comes blaring over the radio and suddenly we're transported back "” to a memorable high-school dance, or to that perfect afternoon on the beach with friends. But what is it about music that can evoke such vivid memories? By mapping the brain activity of a group of subjects while they listened to music, a researcher at the University of California, Davis, now thinks he has the answer: The region of the brain where memories of our past are supported...

In a new fMRI study conducted in the Epidemiology, Biostatistics and Clinical Research Laboratory (Montpellier I University, France) and published by Elsevier in the February 2009 issue of Cortex, researchers found differences among male and female groups on activation strength linked to verbal fluency (words generation). Results from previous fMRI studies identifying the neural basis of sex differences in language production are still in debate. Particularly, the question of group...

A new neuroimaging study on stressed-out students suggests that male humans, like male rats, don't do their most agile thinking under stress. The findings, published this month in the Proceedings of the National Academy of Sciences, show that 20 male M.D. candidates in the middle of preparing for their board exams had a harder time shifting their attention from one task to another than other healthy young men who were not under the gun. Previous experiments had found that stressed rats...

A new study conducted at the Centre for Studies and Research in Cognitive Neuroscience of the University of Bologna, and published by Elsevier in the February 2009 issue of Cortex shows that, in confabulating patients, memory accuracy improves when attentional resources are reduced. Most cognitive processes supporting adaptive behavior need attentional resources for their operation. Consider memory. If memory was a car, attention would be its fuel: New information is not stored into memory if...
