Two Kansas State University psychology researchers have found that although central vision allows our eyes to discern the details of a scene, our peripheral vision is most important for telling us what type of scene we're looking at in the first place, such as whether it is a street, a mountain or a kitchen. "I think the most surprising part of the study is that we didn't really expect peripheral vision to do that well at getting the gist of a scene," said Adam Larson, K-State master's...

Research shows for the first time that the brain can latch on to color and assign it to a different object Color is normally thought of as a fundamental attribute of an object: a red Corvette, a blue lake, a pink flamingo. Yet despite this popular notion, new research suggests that our perception of color is malleable, and relies heavily on biological processes of the eye and brain. The brain's neural mechanisms keep straight which color belongs to what object, so one doesn't mistakenly see a...

BOSTON, Aug. 31 /PRNewswire/ -- A high-tech device that expands the visual field of patients with tunnel vision has passed a collision test in a walking simulator, according to scientists at Schepens Eye Research Institute, in a study published in the September issue of Investigative Ophthalmology and Visual Science. The study found that patients wearing this innovative device, consisting of a tiny camera, pocket-sized computer and a transparent computer display on a pair of glasses, were...

A new study finds a surprising similarity in the way neural circuits linked to vision process information in both sighted individuals and those who have been blind since birth. The research, published by Cell Press in the August 13th issue of the journal Neuron, reveals that category-specific localized activation of a critical part of the visual cortex does not require any prior visual experience and provides fascinating and valuable insight into the evolutionary history of the human...

Arizona Cardinals' Wide-Receiver and Pro Bowl MVP, Larry Fitzgerald Encourages Parents to Take Action TODAY AURORA, Ohio, June 18 /PRNewswire-USNewswire/ -- The College of Optometrists in Vision Development (COVD) is launching their annual campaign to educate the public on the steps they can take to ensure their children aren't struggling with reading and learning because of undiagnosed vision problems. "The public doesn't realize that you need over 15 visual skills to succeed in reading,...

U.S. scientists have found a widely held theory concerning the brain and perception is incorrect and that the brain blocks some information from awareness. Rutgers University researchers have discovered visual input obtained during eye movements is processed by the brain, but blocked from our awareness. The process of seeing requires the eyes to move so light can hit the photoreceptors at the center of each retina, which then pass that information to the brain, the scientists said. "If we...

Researchers find widely held theory on "Saccadic Suppression" is incorrect with discovery that the brain is blocking information from awarenessResearchers at the Center for Molecular and Behavioral Neuroscience (CMBN) at Rutgers University in Newark have identified the need to develop a new framework for understanding "perceptual stability" and how we see the world with their discovery that visual input obtained during eye movements is being processed by the brain but blocked from...

Nocturnal geckos are among the very few living creatures able to see colors at night, and scientists' discovery of series of distinct concentric zones may lead to insight into better cameras and contact lenses. The key to the exceptional night vision of the nocturnal helmet gecko is a series of distinct concentric zones of different refractive powers, according to a study published in the Association for Research in Vision and Ophthalmology's peer-reviewed, online Journal of Vision. This...

When we look at a scene in front of us, we need to focus on the important items and be able to ignore distracting elements. Studies have suggested that inhibition of return (in which our attention is less likely to return to objects we've already viewed) helps make visual search more efficient "“ when searching a scene to find an object, we have a bias toward inspecting new regions of a scene, and we avoid looking for the object in already searched areas. Psychologists Michael D. Dodd...

Video killed the radio star, the old song goes "” but violent video games, a new Tel Aviv University study finds, can also improve the real-world vision of teens who play them. "As a father and brain scientist, I was quite concerned when my kids were growing up and playing video games," says Dr. Uri Polat of Tel Aviv University's Goldschlager Eye Institute, who partnered with the University of Rochester to carry out the new study. "What we see now is that teens who play violent video...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
