Reaching out to the hivemind for references related to persistent representations of reward history (in creatures of all types).
Like these remarkable cells in ACC that reflect reward history between trials of a mixed strategy game ("matching pennies").
Know any?

On X, I have thoughts! I'll report back when I've wrapped my head around the thoughts of others😊.
I'd also add, however, that the nature of the representation of a thing in the brain can shed light on how the brain computes that thing, even if it's not computed in the particular brain area where you are measuring it (but inherited from computations elsewhere).
Along with Kennelly et al, which I think also fits what you’re looking for https://www.nature.com/articles/nn1724
One thing to note is the species difference. When we looked, the persistence is there but weaker in rodents.
