Animals can switch rapidly between multiple well-learned tasks without being explicitly instructed on which task to perform, a cognitive function termed un-cued task switching. This function relies on

The view of the world through the lens of our senses is noisy and incomplete. Confronted with this uncertainty, the brain relies on knowledge about the natural world and the current task context to pe
