Have you ever experienced deja vu?
I think I have deja vu about every few months. Sometimes I just get an eerie feeling like "I know this" or this happened already. But I don't remember it UNTIL it happens. So itís not like being psychic, more like the opposite of being psychic. I've read up on how cognition scientists/neuroanatomists are trying to figure out what causes deja vu and they're trying to duplicate it within the applicable lobes of the brain.
One group of scientists say it may be 'glitch' in your memory making think you're remembering something when you're really not.
Another potential explanation involves a glitch in the exquisitely timed processes of perception and cognition. This theory proposes that sensory impressions of a current experience get detoured in the brain and are not immediately perceived. The information is, however, stored as a memory. This split-second delay in cognition creates the unsettling impression that the event is being experienced and recalled simultaneously.
Whether it's a slippage of timing, a mental hologram or something else entirely, deja vu will remain one of the mind's most tantalizing and elusive tricks.
