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

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...

Lee Rannals for redOrbit.com — Your Universe Online Scientists have finally confirmed what most have already known for generations and generations, men and women see things differently. Scientists reported in the journal Biology of Sex Differences that men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors. Researchers from Brooklyn and Hunter Colleges of the City University of New York compared the vision...

Study Reveals Brain's Mysterious Switchboard Operator
2012-08-17 16:08:49

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found. The researchers report in the journal Science that an area of our brain called the pulvinar regulates communication between clusters of brain cells as our brain focuses on the people and objects that need our attention. Like a switchboard operator, the...
