Mind body dualism

We don't know. But the view that it is a product of brain function is well supported while the notion of material dualism has no evidential support at all. Memory is not well understood in detail, however some of the systems involved have been understood. Essentially memories are encoded in the patterns of interactions between neurons in the brain. Particular regions are specialised for long term memory storage and short term memory storage. I'm not clear on the details of our understanding of recall itself, but will simply note that recall does produce identifiable traces in images of brain activity such as MRI.

Every time you access a memory you change it. In fact, as far as the best research can tell, memory is as much an act of recreation as it is of recall. You seem not to actually remember many details, but instead fill them in is a you think they should be.So in the specific of your idea of a new recording, it seems not; but in the general impression of memories being altered as they are recalled, you're correct.Edited by Mr Jack, : No reason given.
