I was studying this just last month and it’s amazing.
I think it’s the CA3 area of the hippocampus that hangs on to the mental images (images being Visual, auditory, tactile, words, ideas, feelings, whatever multidimensional thing our brains can work with) for a short time.
short term memory.
they used to think it slowly trickled into long-term memory every night back in the early 70s.
but as they’ve been able to actually trace them moving sort of, it takes whatever happened over the last two or three waking periods.
It connects to what you already know and it’s compressed like data.
lots of new stuff added lots of common things simplified.
when you want to reconstruct it it comes through as a narrative usually.
i think that goes through the CA1 of the hippocampus.
