Why Does Déjà Vu Happen?

You walk into a room you've never seen before — and for half a second, your whole body insists you have. That's déjà vu. Not a glitch in the simulation, not a past life. The real explanation traces back to a 1950s operating theatre, where a neurosurgeon accidentally triggered déjà vu with an electrode while his patient was wide awake and talking to him. This video covers what déjà vu actually is, why it's tied to one specific spot in your brain, the two-step memory process behind it, the VR lab that recreated it on purpose, and the brain-scan twist that flipped the whole explanation. 0:00 Intro 0:52 1950s: The Brain Surgery That Found It 2:15 Why It's Tied to One Exact Spot 3:05 The Two-Step Memory Glitch 4:05 The Lab That Recreated Déjà Vu 5:00 The Surprising Twist 5:35 The Full Picture ▶ Watch next:    • The Baader-Meinhof Effect   ▶ Full playlist:    • Psychology Effects Explained   #DejaVu #Psychology #Neuroscience
