Grid cells
1 Grid cells encode for repetitive locations on a hexagonal grid (It will fire when a mouse crosses thes locations). Using many of them we are able to encode location in space (by correlation (if close to two locations both neurons fire)).
Behaviour of 1 grid cell
Modules
Next the grid cell can work as modules to cover the whole plane
Array of modules
Combining multiple modules we are able to localize the whereabouts of an agent in the plane
Grid cells also interact with place cells
