Parallel map theory

There has been some evidence for the idea that the cognitive map is represented in the hippocampus by two separate maps. The first is the bearing map, which represents the environment through self-movement cues and gradient cues. The use of these vector -based cues creates a rough, 2D map of the environment. The second map would be the sketch map that works off of positional cues. The second map integrates specific objects, or landmarks, and their relative locations to create a 2D map of the environment. The cognitive map is thus obtained by the integration of these two separate maps. This leads to an understanding that it is not just one map but three that help us create this mental process. It should be clear that parallel map theory is still growing. The sketch map has foundation in previous neurobiological processes and explanations while the bearing map has very little research to support its evidence.
