| The Representation of Space and the Hippocampus in Rats, Robots and Humans  | | | | Abstract
| Experimental evidence suggests that the hippocampus represents locations within an allo-centric representation of space. The environmental inputs that underlie the rat's representa tion of its own location within an environment (in the firing of place cells) are the distances to walls, and different walls are identified by their allocentric direction from the rat. We propose that the locations of goals in an environment is stored downstream of the place cells, in the subiculum. In addition to firing rate coding, place cells may use phase coding relative to the theta rhythm of the EEG. In some circumstances path integration may be used, in addition to environmental information, as an input to the hippocampal system. A detailed computational m odel of the hippocampus successfully guides the navigation of a mobile robot. The m odel's behaviour is compared to electrophysiological and behavioural data in rats, and implications for the role of the hippocampus in primates are explored. | | | |
