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

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...

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...

Artificial Retina Being Tested On Mice
2012-08-15 06:06:28

Connie K. Ho for redOrbit.com — Your Universe Online Researchers have developed an artificial retina with the ability to restore normal vision based on its work on deciphering the retina´s neural code for brain communication. It´s the first of its kind — an effective prosthetic retina device that can accommodate for blindness in mice. The results of the project are a major breakthrough in working to restore vision for the blind. To begin, the scientists from Weill...

Vision scientists have discovered a new avenue for the treatment of vision loss, one of complications of Parkinson´s disease. Gentle, non-invasive treatment with a soft infra-red light can potentially protect and heal the damage that occurs to the human retina in in Parkinson´s disease, says Professor Jonathan Stone from The Vision Centre and The University of Sydney. “Near infra-red light (NIR) treatment has long been known to promote the healing of wounds in soft...
