The eyes are the Marco Polo of the human body — they travel incessantly across the visual world in front of us, curious for interesting or even insightful information. Tracking someone’s eye movements, therefore, provides insights into their perception and cognition — the eyes are indeed a window to the mind.

That eye movements are necessary for perception to occur in the first place was shown in experiments in the second half of the last century, when scientists showed that preventing eye movements (e.g., through paralysis or by stabilizing an image on the retina) leads to the rapid fading of perception within a fraction of a second.

In “Meet the Scientist”, Martin Rolfs will show demonstrations of how eye movements shape the input to the visual brain — imposing seemingly erratic motion onto the retina like the footage captured by hand-held cameras. He will suggest how the brain exploits the various sensory consequences of eye movements to serve continuous perception and behavior.
