Read the most fascinating explanation of Deja Vu as I was cruising the web trying to figure out what to right for my next article in Valley Trends Magazine. Check this out:
1. The area of your brain responsible for long term memory carries with it all those feelings of familiarity with the memory itself. That’s why when you recall the memory it is familiar, and not a surprise each time you retrieve it. It’s “familiarity” is actually a by-product of the act of recalling information from that part of the brain.
2. Short term memory (the only memory I seem to still possess these days) is responsible for holding onto to stuff (but not grudges, that’s long term memory…hey maybe I do have some of that capability still) in near real time and is the buffer between the consciousness / awareness experience and what is happening from moment to moment out in the real world.
3. Sometimes the brain uses the long term memory nodes for short term memory functions. Nobody is sure if this is a malfunction or a “waking memory dump”….because long term memory commits happen mostly when we sleep. Perhaps this is some sort of glitch where the brain decides to empty out some of the short term memory temporarily and so long term memory is used for extra space while the short term memory is “cleaned up” and prepped for continued use. In either case, when this happens you are experiencing in real time the retrieval of events from long term memory that are happening now. The “familiar” feeling which comes during long term memory access follows along and presto, “I’ve experienced this before.” Yes, you did, about 1/1000 of a second ago.
But then things can get a bit sinister. Imagine if it were possible to artificially induce this process, and even extend the time Deja Vu lasts. This might be one stepping stone on the way to figuring out how to implant false memories.
