Why can't you tickle yourself?

The video explores why people can't tickle themselves, focusing on the brain's role in processing tickling. It explains that when someone else tickles you, the hypothalamus is activated, preparing you for pain and causing laughter as a submission signal. The predictability of self-tickling prevents the brain from being surprised, reducing sensitivity. People with schizophrenia can tickle themselves due to a lack of movement awareness. Experiments attempted to enable self-tickling by waking people during REM sleep and using body illusion techniques, but these were unsuccessful. The video concludes with a suggestion to explore more about the human brain on Sci show Psych.
