Your eyes constantly move to hunt for information, a strategy known as infotaxis. New work from Prof. Mackenzie Mathis's lab @trackingactions.bsky.social shows mice do it too: in a VR task, they actively sought out the most informative views, adjusting as visual info changed doi.org/10.1016/j.cu...
