O'Keefeand Nadel (1978) distinguished between two paradigms for navigation: the locale system for map-based navigation, proposed to be in the hippocampus; and the taxon (behavioral orientation) systems for route navigation. Our World Graph (WG) theory expands the idea of a map by developing the hypothesis that cognitive and motivational states interact. The WG model comprises a network of schemas, which incorporate the world graph properties to produce goal-oriented behavior.

Since most of what we know about hippocampus and navigation is due to rats, the following links are related to some rat resources available on the WEB. Some are really funny, like RAT WARS, a rat version of STAR WARS.
