Visual Sensitivity Improved By Learning To Control Brain Activity
2012-12-05 15:46:31

Wellcome Trust Training human volunteers to control their own brain activity in precise areas of the brain can enhance fundamental aspects of their visual sensitivity, according to a new study. This non-invasive 'neurofeedback' approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example stroke patients. Researchers at the Wellcome Trust Centre for Neuroimaging at UCL used non-invasive, real-time brain imaging that enabled...

Study Finds As We Age, Our Reading Skills Tend To Change
2012-11-26 14:06:40

Lee Rannals for redOrbit.com — Your Universe Online According to research published in the journal Psychology and Aging, word recognition patterns can change as we grow older. University of Leicester psychologists carried out a study into eye-movements of young and old people to examine reading styles in the different age groups. The team discovered for the first time that the way we read words changes the older we get. Researchers conducted experiments that used precise...

Report on devices' potential as visual aids to be presented at the 116th Annual Meeting of the American Academy of Ophthalmology People who have eye diseases that damage their central vision can regain the ability to read quickly and comfortably by using digital tablets, according to a recent study. The research found that people with moderate vision loss could increase their reading speed by 15 words-per-minute, on average. Using a tablet with a back-lit screen resulted in the fastest...

Brain Can Compensate For Minimal Visual Input
2012-11-02 08:57:31

Alan McStravick for redOrbit.com - Your Universe Online Consciousness and perception have long been understood as being interlinked. But our perceptions may be related less to our sense of sight than was previously understood. A new study by researchers at the University of Virginia shows that vision may be less important to our ability to see than is the brain´s ability to process the individual points of light we encounter into more complex images. Their study of the fruit...

The Evolution Of Vision
2012-10-30 04:46:51

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Bristol, published in the Proceedings of the National Academy of Sciences (PNAS), sheds light on the origin of sight in animals, including humans. The research team, led by Dr. David Pisani of Bristol's School of Earth Sciences, used computer modeling to provide a detailed picture of how and when opsins evolved. Opsins are conjugated protein enzymes. These enzymes are components of the visual...

On the road at night or on a tennis court at dusk, the eye can be deceived. Vision is not as sharp as in the light of day, and detecting a bicyclist on the road or a careening tennis ball can be tough. New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels. Like the mirror of a telescope...

Passwords Could Be A Dying Breed
2012-10-16 04:13:22

Alan McStravick for redOrbit.com - Your Universe Online Your first password was probably your pet´s name or the street you grew up on. Then they started requiring numbers and certain punctuation characters. If you are anything like me, and God help you if you are, you have numerous post-it notes littering your computer desk with current and former passwords for any number of websites, accounts and work databases. It took looking to science fiction and high-energy action movies for the...

Visual Perception And Hidden Brain Functions
2012-09-30 08:17:03

Alan McStravick for redOrbit.com - Your Universe Online We´ve all heard the expression, “One hand washes the other”. But according to a recent study, we are learning that an action such as this, or even a mundane task, performed by an estimated 54 percent of Americans daily, such as drinking a cup of coffee, involves a complex set of decisions that our brain must make, often times while hiding the entirety of the decision-making process from us. In the coffee example,...

Color Blindness Linked To Eye Cells Not Brain
2012-09-20 15:52:25

Alan McStravick for redOrbit.com - Your Universe Online Over the past few years, several advances have been made in the field of ocular health.  Much of the research in color vision deficiencies has been conducted in Australia by researchers at The Vision Centre and The University of Sydney. Only a few months back, a major leap forward was achieved in the area of cortical color blindness caused by a traumatic brain injury. That study, like most others, focused on searching the...
