Researchers from the Centre for Vision Research at York University in Canada compared a group of 13 young men in their twenties, who had played video games at least four hours a week for the previous three years, to a group of 13 young men without that experience. The subjects were placed in a functional magnetic resonance imaging (fMRI) machine and asked to complete a series of increasingly difficult visuomotor tasks, such as using a joystick or looking one way while reaching another way.
"By using high resolution brain imaging (fMRI), we were able to actually measure which brain areas were activated at a given time during the experiment," said Lauren Sergio, associate professor in the Faculty of Health at York University. "We tested how the skills learned from video game experience can transfer over to new tasks, rather than just looking at brain activity while the subject plays a video game."
The study found that during the tasks the less experienced gamers were relying most on the parietal cortex (the brain area typically involved in hand-eye coordination), whereas the experienced gamers showed increased activity in the prefrontal cortex at the front of the brain.
The finding that using visuomotor skills can reorganize how the brain works offers hope for future research into the problems experienced by Alzheimer's patients, who struggle to complete the simplest visuomotor tasks.
Lead author Joshua Granek added that, in future, it would be interesting to study if the brain pattern changes are affected by the type of video games a player has used and the actual total number or hours he has played, and to study female video gamers, whose brain patterns in earlier studies were different than those of males.

Cortex is an international journal devoted to the study of cognition and of the relationship between the nervous system and mental processes, particularly as these are reflected in the behaviour of patients with acquired brain lesions, normal volunteers, children with typical and atypical development, and in the activation of brain regions and systems as recorded by functional neuroimaging techniques. It was founded in 1964 by Ennio De Renzi. The Editor in-chief of Cortex is Sergio Della Sala, Professor of Human Cognitive Neuroscience at the University of Edinburgh.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
