Seeing what they see – a new method to reconstruct the point-of-view of a freely moving animal

How does a mouse use its eyes to accurately target and catch a fleeing cricket? Researchers at caesar developed a new method to reconstruct the ‘view through the eyes’ of an animal as it detects and tracks its prey. They recorded eye and head movements of freely moving mice hunting crickets whilst the position of both the mice and prey were being measured in the arena. A new environment digitization approach, combined with mathematical analysis, recreated what the mouse would see during its hunt. This enabled the “view through the eyes” to be correlated with a distinct behavior. Unlike humans, mice cannot voluntarily move their eye position.
