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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
