Are memories stored like files, or as gist plus a few unusual details that the brain regenerates each time you remember?
It decides how far generative AI is a fair model of memory — and explains why memories change and false memories happen.
Memory is clearly constructive — remembering and imagining share brain networks. A 2024 model shows a generative account can reproduce many effects, but competing accounts explain several of the same findings.
A neutral summary kept current by super users, not a verdict.
Memory is generative: the hippocampus keeps unusual details and trains the cortex to regenerate the rest.

Constructive effects arise without a generative model, e.g. from multiple traces or context binding.
