This chapter reviews what is known about place cells. Under normal circumstances, the location in which a place cell fires — its place field — is anchored to the visual landmarks within the environment. However, place cells also fire in the dark, and evidence shows that their firing also reflects path integration. Place cells are sensitive to boundaries in the environment, and the boundary-vector model developed by Neil Burgess and colleagues posits that place cells are the product of boundary cells tuned to walls or boundaries in different directions. Place cell firing is also modulated by the behaviour of the animal, and can reflect its intended destination. Place cell-like activity is found in non-human primates and in humans. Imaging studies in humans have provided some support for a role of the hippocampus is navigation and cognitive mapping, and have also highlighted a contribution from the parahippocampal gyrus.

Keywords:   place cells, path integration, boundary vector cells, parahippocampal gyrus, hippocampus
