Seeing Things Differently: The Secret Life of Our Eyes

Tracking our eyes’ motion when we are faced with a visual challenge may help researchers uncover neural encoding in the brain

Measuring the response to novelty: A mouse repeatedly touches the object and pulls away (nose and whisker contacts are color-coded; d is the distance of the snout from the object)
A mathematical model shows how our brains may take in novelty
Our nerves respond to a range of stimuli

Why does a background noise that stops and suddenly starts again get our attention?
