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)
Collision-course science: when a single locust joins a swarm
If an animal is to cope with changing environmental conditions, activity in its nervous system must also change. Scientists from Cambridge and Oxford are studying these changes in collision-detecting nerve cells in the visual system of the locust, an insect that alternates between two lifestyles. Their research, to be presented at the SEB... view more... (2003-03-26)

Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
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)
Study suggests human visual system could make powerful computer
Since the idea of using DNA to create faster, smaller, and more powerful computers originated in 1994, scientists have been scrambling to develop successful ways to use genetic code for computation. view more (2008-07-24)
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)
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)
Face facts: People don't stand out in crowds
Why is it difficult to pick out even a familiar face in a crowd? We all experience this, but the phenomenon has been poorly understood until now. view more (2008-01-22)
Scientists uncover why picture perception works
A team of scientists has solved a key mystery of visual perception. Why do pictures look the same when viewed from different angles? view more (2005-09-22)
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)
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)
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)
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)
Viagra®, unlikely tool for vision research, slows the visual response to flickering light
Therapeutic doses of Viagra® have been shown to influence the rate at which visual signals are integrated by the brain, affecting the way quick, repeated events, such as flickering light, are perceived. view more (2006-01-24)
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)
Study reveals we seek new targets during visual search, not during other visual behaviors
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... 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)
Growth factors and environment combine to increase brain maturation
A new study showing that growth factors and the environment combine to increase brain maturation appears in the May 30th issue of the online, open-access journal PLoS ONE. view more (2007-05-30)
Reorganization of brain area for vision after stroke: May yield new treatments for brain injury
New evidence from a patient shows that the area of the brain that processes visual inputs can reorganize after an injury caused by stroke. view more (2007-09-05)
