A new study at Baylor College of Medicine in Houston helps explain why practice makes perfect. Baylor researchers found that neurons in the visual cortex, the part of the brain responsible for vision, were more active when study monkeys anticipated the occurrence of predictable events. The results of the study were published in the Oct. 10 issue of Nature. "We really dont have a great understanding of what changes in the brain when we practice things," said Dr. Geoffrey M. Ghose, first author of the paper and an assistant professor of neuroscience at Baylor. "These results show that as we practice and anticipate which events are going to happen, the brain is also preparing itself."
Dr. John H. R. Maunsell, a professor of neuroscience at Baylor and a Howard Hughes Medical Institute investigator, is the studys lead author.
Researchers at Baylor trained two macaque monkeys to pay attention to changes at a specific location of a display screen. They were rewarded with juice if they pulled a lever when the change occurred. The activity of neurons in the visual cortex was measured during the experiment.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
