New research has found that the brain continues to accept ambiguous visual information about an object in motion even when it conflicts with more reliable information that we can touch. The studies, which appear in the June 7 issue of the journal Psychological Science and the forthcoming June issue of the journal Cognitive, Affective, & Behavioral Neuroscience, provide new insights into the way the brain blends and balances information from different senses.

The research, conducted by Vanderbilt psychologists Randolph Blake, Centennial Professor of Psychology, and Thomas W. James and Kenith V. Sobel, research associates, found that the region of the brain that specializes in processing visual movement-the middle temporal visual center, or MT-also responds to motion that we feel. But they were surprised to discover that when individuals were presented with an ambiguous visual image and were able to touch that object, their brains did not fuse the visual and touch inputs into a single, accurate representation. Instead, the researchers found that the brain keeps the two inputs separate and accepts a degree of "cognitive dissonance" when the two conflict.
"This suggests that there is naturally a higher level of inconsistency between seeing and feeling something moving than there is between seeing and feeling somethings shape," says James.

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...
