GRID/Displacement cell uniqueness

Dear Ladies/Gents,

I’d like to ask for your opinion on uniqueness of grid cell patter for every environment. I understand there’s plenty of evidence for grid cells anchoring to learned environment.

My question is - is there any paper/suggestion/model that is explaining how exactly the anchoring of grid cells to a specific environment works, please?

To be more specific - let’s say the paper “A Framework for Intelligence and Cortical Function Based on Grid Cells in the Neocortex” (link) is describing 3 main grid cell properties, the 3rd being “(3) Locations are unique to each environment”. Is there any mechanism/model/paper describing how exactly this is done?
Also in another paper " Locations in the Neocortex: A Theory of Sensorimotor Object Recognition Using Cortical Grid Cells" (link) I found a reference saying that grid cells activate a random location - but I get that it’s just a way of thinking of how to make it happen and it’s not really random.
I know there’s evidence proving that grid cells are anchored/remapped, but I’m not able to find any mechanism of how exactly this is happening. I can imagine a way or two, with or without randomness, but I’m trying to implement it and I’m having the feeling that I missed one crucial paper or that I overlooked something.
If there is no paper but you gave this topic a thought or two - what is your view on this?

Thank you in advance and best of luck.



Hello Martin,

There are several competing ideas about how grid cells form and anchor to their environment. In my opinion, the best of these ideas is (Kropff & Treves, 2008) which I explain in depth at:

I hope this helps


Hi dmac,

ah, very nice, am already going through the paper. Thank you for your help!
