This reminds me of times when I go back home and I have to remember a route to get somewhere, say the mall, and in my head I following a path that I remember. Every Time I need to go somewhere in a car it is the most obvious that I am following that path.
I wonder if this can be used to help people remember events by using locations to help bring that memory forward. Say you show a picture to someone on a day something traumatic has happened and the location actually helps them remember and they can walk through that situation.
The original article is something really exciting to read, the more that we can understand about how we can navigate through our mental space would help so many people and it's really cool to think about.
Random thought is if you can apply network theory to the hexagonal array or the grid like pattern? If it can be, my first thought would be to apply Triac closure and other principles to see how memories are tied to one another and the connections between them.
So... I wonder then if there is duality in this mapping like between frequency/time domains with a Fourier transform of signal over time, just, instead, over a concept domain
(grid/place) cells :: spatial resolution / location
cells, which if combined, encode concepts :: conceptual resolution/frequency (??)
I'm not sure exactly what I'm trying to say, beyond "I think so, yeah". It's a super interesting area of exploration and either it hasn't been looked into enough, or I don't know the right words to look for. I can feel a thread linking concepts like mental models, systems theory, cybernetics, Christopher Alexander's work on pattern languages, and so on.
It was apparently used by Ancient Greek and Roman orators as mnemonic device.
