00:00Try to tickle your own arm right now.
00:03Nothing happens.
00:04Here's why.
00:06Meet your cerebellum,
00:08the part of your brain that predicts
00:10every move you're about to make.
00:16The moment you decide to move your own hand,
00:19it sends out a preview
00:21of exactly what's coming.
00:26That preview cancels out the sensation.
00:30Before it even arrives.
00:32Like muting a sound you know is coming.
00:37But when someone else touches you,
00:40there's no preview.
00:42You know preview.
00:43Your brain has zero warning.
00:47So the same touch feels completely different,
00:50mild from you,
00:51intense from someone else.
00:55It's not that you're immune to tickling.
00:58It's that you're brain to tickling.
01:00It's that your brain can't surprise itself.
01:06It's not that you're navigating.
01:08it's not that you're Бoing,
01:08it's not that you'reтер öBT too cares.
01:09But you're listening to it.
01:09It's maybe you're not going to be effect.
01:09But you're doing something else.
