With our eyes constantly darting back and forth, the brain is faced with the equivalent of the kind of shaky video stream produced by a hand-held camera. Not only does the brain find a way to compensate for our constantly flickering gaze, but researchers at the Salk Institute for Biological Studies have found that it actually turns the tables and relies on eye movements to recognize partially hidden or moving objects.

Free will takes flight: how our brains respond to an approaching menace
08-23-2007 · EurekAlert!
Wellcome Trust scientists have identified for the first time how our brain's response changes the closer a threat gets. Using a "Pac Man"-like computer game where a volunteer is pursued by an artificial predator, the researchers showed that the fear response moves from the strategic areas of the brain towards more reactive responses as the artificial predator approaches.

New interview technique could help police spot deception
06-07-2007 · EurekAlert!
Shifting uncomfortably in your seat? Stumbling over your words? Can't hold your questioner's gaze? Police interviewing strategies place great emphasis on such visual and speech-related cues, although new research funded by the Economic and Social Research Council and undertaken by academics at the University of Portsmouth casts doubt on their effectiveness. However, the discovery that placing additional mental stress on interviewees could help police identify deception has attracted interest from investigators in the UK and abroad.

Japanese beetle may help fight hemlock-killing insect
09-10-2007 · EurekAlert!
The eastern hemlock, a tall, long-lived coniferous tree that shelters river and streamside ecosystems throughout the eastern United States and Canada, is in serious danger of extinction because a tiny, non-native insect is literally sucking the life out of it. Entomologists at Virginia Tech are now studying a beetle from Japan that may be a natural predator of Adelges tsugae, or hemlock woolly adelgid.

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.

Why does the world appear stable while our eyes move?
02-14-2008 · EurekAlert!
Whenever we shift our gaze, attention is directed to a new target. This shift in attention causes a brief compression of visual space, according to a study published Feb. 15 in the open-access journal PLoS Computational Biology. Researchers show a direct correlation between visual perception and eye movement control.
