Scientists Figured Out How To Trigger Déjà Vu On Purpose

Why You Get Déjà Vu You've had that feeling: this exact moment has happened before, and you're certain of it. It hasn't. What's actually happening is two parts of your brain disagreeing in real time, one flagging a false sense of familiarity, the other failing to catch the error fast enough before you feel it. This video breaks down what's actually going on in your head: the two brain regions that collide every time déjà vu hits, the experiment that triggered déjà vu on purpose using virtual reality, why the eerie feeling that you "know what happens next" is a second illusion stacked on the first, the strange opposite called jamais vu that you can trigger yourself in about a minute, and why you get déjà vu far less now than you did as a teenager. By the end you'll understand why the one feeling you can trust least is certainty, and why déjà vu might be a sign your memory is working exactly as it should. #dejavu #deja #memory #brain #neuroscience #psychology #sciencefacts #howthebrainworks #jamaisvu #mind #brainfacts #humanbrain #psychologyfacts #didyouknow #science
