Eyeball Reflexes: Security and Biometrics That Cannot Be Spoofed Sep 5, 2008
Nishigaki and Arai have turned to blind spot position and the so-called saccade response for their biometric ... Saccade response is the repeated, tiny, left-to-right movements made when our eyes track something moving right to left, and vice versa ... By using the blind spot position as a trigger to induce saccades, user authentication can be done by displaying a target within and outside the person's blind spot and using eye tracking technology to measure the reflex time taken until eye...

Tracking what you're looking at Sep 14, 2007
These movements, called saccades, are controlled by sets of six muscles attached to the outside of each eye ... Each saccade lasts just 20 to 200 milliseconds. (San Diego Union-Tribune)

Brain Pathway Brings Order to Visual Chaos Nov 13, 2006
The world you see around you appears perfectly stationary, even though your eyes dart back and forth two to three times every second in little hops called saccades ... Researchers had already observed that brain cells in this region seem to anticipate where the eye's center of focus will move to after an impending saccade, making it a reasonable place for corollary discharges to end up ... As would be expected for the corollary pathway, the frontal cortex of the injected monkeys consistently... (Scientific American)
Why our shifty eyes don't drive us crazy Nov 9, 2006
When we scan a visual scene with quick eye movements known as saccades (top), the retinas send a series of 'snapshot' images to the brain that must be integrated properly. Our eyes are constantly making saccades, or little jumps ... They suggested that this pathway might cause visual neurons of the cortex to suddenly shift their receptive field--their window on the world--just before a saccade. (EurekAlert!)
Unusual Data On Rapid Eye Movements Shed New Light On Brain And Inhibiting Behavior Aug 17, 2006
The study took an unexpected twist when doctoral student Sandy Saavedra reported a high level of multiple saccades, which are rapidly occurring glances toward a secondary object, van Donkelaar said ... "In adult studies there are so few multiple saccades that they are statistically insignificant, maybe just 5 percent of the time and attributed to mistakes by the participants. But in these results, we were seeing multiple saccades in 25 percent of the trials. It was a complete surprise. So we... (Science Daily)
