How do we know where we are? How do we find our way? Why do we sometimes get lost? Neuroscientific research has revealed brain cells in the hippocampal formation that provide an exquisite representation of an animal or human being's current location and heading. This 'cognitive map' allows us to find our way around and provides the basis for lasting memories.
Philosophical Transactions B has published a theme issue illustrating this exceptionally integrative branch of neuroscience, in which we join the dots, from molecules to cells, to complex behaviour and human cognition. Here, Ruth Milne talks to two of the guest editors, Tom Hartley and Colin Lever, about the issue.
