Ever catch a glimpse of someone but cant quite fit a name to go with the face? While its something that happens to everyone, for older people especially, difficulty in retrieving names is a common frustration.
Scientists at the University of Arizona in Tucson are trying to determine what goes on inside the brain when it sees a face. How, for instance, does the brain recognize faces and retrieve the names to go with them? Also, how does the brain determine whether the information that it has retrieved is accurate? "In other words, how do we know when we come up with a possible memory that its the right one, as opposed to something we dreamt or imagined," said Alfred Kaszniak, one of the authors of the study.
The lead author of the study, "Feeling of Knowing for Faces: An fMRI Study," Jasmeet Pannu, is a graduate student at the University of Arizona in Tucson. Steven Rapcsak, a UA associate professor of neurology and a behavioral neurologist at the Veterans Medical Center in Tucson, and Kaszniak, a professor and head of the psychology department at the UA, are the other authors. Their latest research is being presented at the annual Society for Neuroscience meeting in San Diego.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
