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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
