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. In a paper published online this week in Nature, researchers at the University of Pittsburgh and the National Eye Institute for the first time provide a circuit-level explanation as to why.

1. The eyes have it: What do we see when we look at ads?
   08-07-2007 · EurekAlert!
   How do consumers look at advertisements? Most marketing textbooks advance the theory that looking at ads is a predominantly "dumb process," driven by visual stimuli such as the size of the ad or the color of the text. However, new research by researchers from the Netherlands and the University of Michigan uses eye-tracking software to reveal that it may be our goals -- the tasks we have in mind -- that drive what we pay attention to, even during a few seconds of ad exposure.

2. Blue eyes -- A clue to paternity
   10-23-2006 · EurekAlert!
   Before you request a paternity test, spend a few minutes looking at your child's eye color. According to studies, published this week in Behavioral Ecology and Sociobiology, the human eye color reflects a simple, predictable and reliable genetic pattern of inheritance. The researchers show that blue-eyed men find blue-eyed women most attractive. According to the researchers, it is because there could be an unconscious male adaptation for the detection of paternity, based on eye color.

4. From the corner of the eye: Paying attention to attention
   07-05-2007 · EurekAlert!
   Every kid knows that moms have "eyes in the back of their heads." We are adept at fixing our gaze on one object while independently directing attention to others. Salk Institute neurobiologists are beginning to tease apart the complex brain networks that enable humans and other higher mammals to achieve this feat.

   In "Star Trek: The Next Generation," Geordi La Forge is a blind character who can see through the assistance of special implants in his eyes. While the Star Trek character "lives" in the 24th century, people living in the 21st century may not have to wait that long for the illuminating technology.

8. The eyes have it
   01-29-2008 · EurekAlert!
   Using the radiocarbon dating method and special proteins in the lens of the eye, researchers at the University of Copenhagen and Aarhus can now establish, with relatively high precision, when a person was born. This provides a useful tool for forensic scientists who can use it to establish the date of birth of an unidentified body and could also have further consequences for health science research. The findings are published in the online, open-access journal PLoS ONE on Jan. 30.

10. How the brain copes with shifty eyeballs
    04-18-2007 · EurekAlert!
    Neurobiologists have pinpointed brain regions critical to one of the brain’s more remarkable feats -- piecing together a continuous view of the world by integrating snippets of visual input from constantly moving eyes. Since the eyeball has only a narrow field of clear view, it must continually make tiny shifts to sample the visual world. And during these shifts, which last thousandths of a second, people are essentially blind.
