I know it's hardly original before anyone points it out, but I'm trying to get my head around the results of such a procedure, and how it would manifest itself. If someone, unbeknown to them, was implanted with the false memory of a murder they supposedly committed, would they not remember a time before this implant, when they could remember not having committed the murder? In other words, would their thought process be, 'Why am I suddenly plagued by the memories of committing a murder?' ? Given that this person is fully aware of the technique, and is heavily involved in it, would it be immediately obvious to them they'd been implanted with these memories?
