In the rodent an internal model of the external world is encoded by hippocampal pyramidal cells, called "place cells", which carry information in addition to posisiton. We show that while place cell firing is overdisposed in rats during foraging in an open arena, the firing is less overdisposed during the same behavior in the same environment, when the rats have been trained to use only room-based and not arena-based cues to navigate.
