Infliximab Could Prevent Sight Loss From Behcet's Disease (p 295)
A drug used to treat rheumatoid arthritis and Crohn's disease could play an important role in preventing sight loss associated with the inflammatory disorder Behcet's disease, suggest authors of a fast-track research letter published in this week's issue of THE LANCET. Beh'§et's disease is a rare condition (although with increased incidence in... view more... (2001-07-25)
Sense and sensibility in short-term memory
More than three centuries ago, Sir Isaac Newton reflected on the similarities between the sense of hearing and the sense of sight. Newton's speculations were impossible to test scientifically, until now. view more (2007-02-20)
Dyslexia Research
New findings from Salzburg concerning poor reading and spelling Vienna/Salzburg (Austrian Science Fund) - A not inconsiderable number of children, particularly boys, have unexpected difficulties in learning to read and spell. It is estimated that up to 10 % of all children are affected. With the support of the Austrian Science Fund, Heinz Wimmer,... view more... (2002-03-20)
Hand Can't Be Fooled, Study Shows
Research published in the March issue of Psychological Science, a journal of the Association for Psychological Science, is suggesting that we process images in two very distinct ways. view more (2008-03-11)
NIST tool helps Internet master top-level domains
At the request of a worldwide Internet organization, a computer scientist at the National Institute of Standards and Technology (NIST) developed an algorithm that may guide applicants in proposing new "top-level domains"-the last part of an Internet address, such as .com, that people type in navigating the Web. view more (2008-05-19)
Retina adapts to seek the unexpected, ignore the commonplace
Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace. The scientists report in this week's issue of the journal Nature on their finding that this principle of novelty-detection... view more... (2005-07-11)
NYU, Salk Institute neuroscientists offer new path for measuring visual responses to complex images
Neuroscientists at New York University and the Salk Institute have developed a new technique for measuring visual responses to complex images. The method consists of building a model based on cell responses to a range of stimuli, then asking how accurate the model is by comparing the model predictions with the actual responses of a cell to... view more...

Penn researchers report that gene therapy awakens the brain despite blindness from birth
Researchers at the University of Pennsylvania have demonstrated that gene therapy used to restore retinal activity to the blind also restores function to the brain's visual center, a critical component of seeing. view more (2007-06-26)
Speaking Eyes
If you speak only one language, do not feel upset. Simultaneously with your native language or perhaps even earlier, you have learned one more language - a visual one. A person perceives everything around through the eyes. The eyes "speak" their own special language. This language has letters, words and even grammar rules. Psychologists... view more... (2005-03-25)
Sight can recover quickly in amblyopia
New research findings led by Thomas Krahe and Ary S. Ramoa of Virginia Commonwealth University School of Medicine offer two pieces of good news for treating children with amblyopia. view more (2005-10-20)
Right-hand digits: study reveals new visual distortion effect
The amount of the discount may be less important than the numerical value of the farthest right digit, explains a new study from the Journal of Consumer Research. Keith S. Coulter (Clark University) and Robin A. Coulter (University of Connecticut) are the first to identify a visual distortion effect that may influence how consumers look at sale... view more...

Action video games improve vision
Video games that involve high levels of action, such as first-person-shooter games, increase a player's real-world vision, according to research in today's Nature Neuroscience. view more (2009-03-30)
Study Suggests Buddhist Deity Meditation Temporarily Augments Visuospatial Abilities
Meditation has been practiced for centuries, as a way to calm the soul and bring about inner peace. According to a new study in Psychological Science, a journal of the Association for Psychological Science, there is now evidence that a specific method of meditation may temporarily boost our visuospatial abilities (for example, the ability to... view more...

Cortical plasticity: it's time to get excited about inhibition
Research from Brandeis University published online this week in Nature offers new insight into how neural circuits are shaped by experience. The article provides new evidence for the mechanisms that affect the ability of the visual cortex to plastically rearrange itself following periods of visual deprivation. view more (2006-08-24)
Innovative surgery corrects vision in kids with neurological disorders
Children with cerebral palsy and other neurological problems often have extremely poor eyesight. view more (2006-10-11)
Adult brain can change, study confirms
It is well established that a child's brain has a remarkable capacity for change, but controversy continues about the extent to which such plasticity exists in the adult human primary sensory cortex. view more (2007-09-06)
Visual Learners Convert Words to Pictures in the Brain And Vice Versa, Says Penn Psychology Study
A University of Pennsylvania psychology study, using functional magnetic resonance imaging technology to scan the brain, reveals that people who consider themselves visual learners, as opposed to verbal learners, have a tendency to convert linguistically presented information into a visual mental representation. view more (2009-03-25)
Wired for sound: How the brain senses visual illusions
In a study that could help reveal how illusions are produced in the brain's visual cortex, researchers at the UCSD School of Medicine have found new evidence of rapid integration of auditory and visual sensations in the brain. view more (2007-04-12)
Researchers report gene associated with language, speech and reading disorders
A new candidate gene for Specific Language Impairment has been identified by a research team directed by Mabel Rice at the University of Kansas, in collaboration with Shelley Smith, University of Nebraska Medical Center, and Javier Gayán of Neocodex, Seville, Spain. view more (2009-08-28)
Why our shifty eyes don't drive us crazy
Our eyes are constantly making saccades, or little jumps. Yet the world appears to us as a smooth whole. Somehow, the brain's visual system "knows" where the eyes are about to move and is able to adjust for that movement. view more (2006-11-09)
