What this research 'changes' about your ideas about memory depends a lot on what your ideas about memory were before reading the article. Here's what the work shows, according to the article: "a memory isn't a facsimile of past perceptions that gets replayed. Instead, it is more like a reconstruction of the original experience, based on its semantic content." I think we mostly agree that memory is a reconstruction, not a literal replaying. I think it's less certain (by a wide margin) that it's based on semantic content (though of course this depends a lot on what you mean by 'semantic content'). Anyhow, interesting article. Love the brain graphic.
