Thought this would be interesting. Here is information I sourced from Wikipedia, Nancy Kanwisher's MIT lectures + others.
Grid cells track overlapping hexagonal-like grids. I'm not sure how to explain it so here's an article that explains grid cells. They can also be used to encode for relationships between abstract concepts.
Place cells track a specific location on a map. They overlap a bit. It fires when an animal is in that location. The location can be remapped. The same place cell can be reused for different maps. Cognitive maps. They are essential for episodic memory like to remember where certain objects are.
Boundary/border cells track where the boundaries of a location are. This is used in reorientation. It might sound strange but to reorient itself, an animal uses the shape of the space instead of cues like colour. It may be because the physical shape of a space rarely changes too much. Other cues such as colour could change from season to season.
Spatial view cells are found in primates. These cells fire when a part of the environment is in view. For instance, primates could use this to recall where fruit is even when there are no fruit on the fruit tree at the moment.
They are also Speed cells and Head direction cells.
