Why You Can't Tickle Yourself

Try it right now. Run a finger up your own side. Nothing. Your body, which panics at a single unexpected breeze, feels absolutely nothing when you do it yourself. Here's what's actually happening: your brain sends a copy of every movement to itself, predicts exactly what it will feel like, and cancels it out before you feel it. That's why you can't tickle yourself, and why a tiny delay can trick your brain into letting you. My Curious Body explains the strange, ridiculous, brilliant things your body does, with a host who is mildly exasperated to be doing it. Not medical advice, just curiosity grounded in real science. #MyCuriousBody #tickle #neuroscience #cerebellum #humanbody #science
