The brain ‘rotates’ memories to save them from new sensations
I don't remember where I came across this (was probably some pop neuroscience blog or maybe radiolab), but there was some theory about how memories seem subject to degredaton when you recall them a lot, and less so when you don't.I guess that would sort of be like the opposite of DRAM - cells maintain state when undisturbed, but the "refresh" operation is lossy.
