This chapter opens with a description of the discovery of head direction cells. It also describes grid cells — a remarkable type of spatially tuned neuron that fires in a grid-like pattern within any environment. Next the anatomy of the head direction/grid cell circuit is described. Following this, the basic properties of head direction cells are summarised. Like place cells and grid cells, the spatial orientation of head direction cells is anchored to visual landmarks in the environment when these are available. In some instances, spatial behaviour and the behaviour of head direction cells is correlated. Head direction firing also reflects path integration, and head direction cells maintain their specific direction across connected environments. However, this integration is prone to error, and the accumulation of such error may underlie misorientation.

Keywords:   head direction cells, grid cells, spatial orientation, path integration, spatial behaviour
