Scientists achieve first measurements of selectivity mechanism
a. Example of the memory filtering test conducted by University of Oregon researchers. Participants must remember only the red rectangles and ignore the blue rectangles.
b. Brainwaves for high capacity and low capacity participants. Blue line is activity for 4 red items; Black line is for 2 red items; Red line is for 2 red items and 2 blue items. If the red line is close to the black line, subjects are efficient at keeping out the blue items. If the red line is close to the blue line, the subjects are unable to keep the blue items from popping into memory.
c. Correlation between a persons memory capacity and how good they are at keeping the irrelevant items out of memory.
Even if you could get more RAM for your brain, the extra storage probably wouldnt make it easier for you to find where you left your car keys.
What may help, according to a discovery published Nov. 24 in the journal Nature, is a better bouncer – as in the type of bouncer who manages crowd control for nightclubs. The study by Edward Vogel, an assistant professor of cognitive neuroscience at the University of Oregon, is the first to demonstrate that awareness, or "visual working memory," depends on your ability to filter out irrelevant information.

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...
