The Real Reason Behind Déjà Vu

That eerie feeling that you've been in this exact spot before isn't a glitch in reality. A researcher at the University of St Andrews figured out how to trigger it on command, using nothing but a list of words — and brain scans confirmed exactly what's happening when it hits. In this video, we look at the real neuroscience: how a simple false-memory trick reliably produces the feeling of déjà vu in a lab, why the brain's memory centers stay quiet while frontal error-checking regions light up instead, and what this reveals about déjà vu's strange link to age and epilepsy.
