Learned motor programs directly influence the visual perception of movements
When novel movements are learned-for example, in sports-visual and motor learning take place simultaneously. view more (2006-01-10)
UK Childhood Blindness More Common Than Previously Thought (p 1359)
Increased ethnic diversity and greater survival of low-birthweight babies is contributing to a higher proportion of children becoming visually impaired or blind, according to authors of a UK study in this week's issue of THE LANCET. The study also highlights how childhood visual impairment is associated with lower socio-economic status. The... view more... (2003-10-22)
Brain's timing linked with timescales of the natural visual world
Researchers have long attempted to unravel the cryptic code used by the neurons of the brain to represent our visual world. By studying the way the brain rapidly and precisely encodes natural visual events that occur on a slower timescale, a team of Harvard bioengineers and brain scientists from the State University of New York have moved one step... view more...

Study predicts 40 percent increase in blindness in Nigeria by 2020
By 2020, 1.4 million Nigerians over age 40 will lose their sight, and the vast majority of the causes are either preventable or treatable, according to the Nigeria National Blindness and Visual Impairment Study Group. view more (2009-09-09)
Noncorrectable vision problems associated with shorter lifespan in older adults
Visual problems that cannot be corrected are associated with increased risk of death among individuals between the ages of 49 and 74, and all visual impairments may be associated with the risk of death in older adults. view more (2009-10-13)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
Blindsight: How brain sees what you do not see
Blindsight is a phenomenon in which patients with damage in the primary visual cortex of the brain can tell where an object is although they claim they cannot see it. view more (2008-10-15)
New study shows those blinded by brain injury may still 'see'
Except in clumsy moments, we rarely knock over the box of cereal or glass of orange juice as we reach for our morning cup of coffee. New research at The University of Western Ontario has helped unlock the mystery of how our brain allows us to avoid these undesired objects. view more (2009-09-03)
Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years. view more (2008-08-12)
Study Indicates How We Maintain Visual Details In Short Term Memory
Working memory (also known as short term memory) is our ability to keep a small amount of information active in our mind. view more (2009-02-23)
Study Highlights Need For UK Childhood Screening For Amblyopia (pp 597, 621)
Authors of a study in this week's issue of THE LANCET highlight how the risk of visual loss in the normal eye for individuals with one lazy eye (amblyopia) is greater than previously thought, strengthening the need for effective screening programmes to detect amblyopia in early childhood. Monocular amblyopia occurs in at least 1% of individuals... view more... (2002-08-21)
Blink, and the brain misses it
We would immediately notice if the outside world suddenly went dark every few seconds. But we rarely become aware of our blinks, even though they cause a similar reduction in the amount of light entering the eye. So why are we not aware of the frequent mini-blackouts caused by blinks? view more (2005-07-26)
Low birth weight babies with reduced occipital regional volumes at higher risk for visual impairment
Preterm infants with smaller occipital brain volumes are more likely to experience impaired visual function in early childhood according to a study published in the August 2006 issue of Investigative Ophthalmology & Visual Science (IOVS). view more (2006-08-30)
Epilepsy drug causes eye problems in over 40 per cent of cases
Vigabatrin, a drug used to treat epilepsy, causes eye problems in over 40 per cent of those prescribed it, shows a study in the Journal of Neurology Neurosurgery and Psychiatry. Vigabatrin was licensed in the UK in 1989 and was the first anti-epileptic drug to come on to the marked since the 1970s. Although effective, it has been associated with... view more... (2002-08-20)
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)
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)
Fluctuating eye pressure associated with visual field deterioration in glaucoma patients
Fluctuations in eye pressure may be associated with a decreasing peripheral field of vision in patients with glaucoma, even if their eye pressure remains low overall. view more (2007-08-14)
Early vision screening associated with better eyesight in children with amblyopia
Children who screen positive for amblyopia, reduced vision in one eye, before age 2 appear to have better visual outcomes than those whose vision problems are detected during screenings between ages 2 and 4. view more (2008-04-15)
Audio-visual tools for Speech & Language Therapists
Latest developments from the Department of Electronics at the University of Kent at Canterbury (UKC) are proving to be invaluable audio-visual tools for Speech & Language Therapists around the world. Senior Lecturer Steve Kelly has been working on an already existing technology called SNORS+ and developed a system that combines time-coded... view more... (2002-04-25)
Multiple genes permit closely related fish species to mix and match their color vision
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using photoreceptors that are attuned to particular wavelengths of... view more...
