Abstract

Central to the concept of the ‘cognitive map’ is that it confers behavioural flexibility, allowing animals to take efficient detours, exploit shortcuts and avoid alluring, but unhelpful, paths. The neural underpinnings of such naturalistic and flexible behaviour remain unclear. In two neuroimaging experiments we tested human subjects on their ability to navigate to a set of goal locations in a virtual desert island riven by lava, which occasionally spread to block selected paths (necessitating detours) or receded to open new paths (affording real

when participants encountered tempting false shortcuts that led along suboptimal paths that needed to be differentiated from real shortcuts. We also report modulation in event-related

as to how the brain supports navigation and planning in dynamic environments.
