This is pretty interesting, and thanks for the link. This is now making me think how people with ADHD (like myself) can use this to understand how they think. I just read people with ADHD can start creating false memories with situations because they may not have been paying attention in that situation, but I don't want to go on too much of a tangent.
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.
