The medial entorhinal cortex is part of a neural system for mapping the position of an individual within a physical environment1 . Grid cells, a key component of this system, fire in a characteristic hexagonal pattern of locations2 , and are organized in modules3 that collectively form a population code for the animal's allocentric position1 . The invariance of the correlation structure of this population code across environments4,5 and behavioural states6,7 , independent of specific sensory inputs, has pointed to intrinsic, recurrently connected continuous attractor networks (CANs) as a possible substrate of the grid pattern1,8-11 ...
