Identifying our position in space is critical for navigation, and also for our ability to form memories of behavioral episodes, because these occur in a specific time and place. Understanding the neuronal mechanisms underlying these abilities has been an enduring question in neuroscience: how do our brains combine external sensory information with internal self-motion cues to produce a circuit-level representation of spatial location, and how are these representations used to help us understand where we are and to allow us to successfully navigate through our environment?
