Your defense mechanism when tickled

Researchers have found tickling laughs (different than laughs caused by finding something to be humorous) cause the hypothalamus part of the brain to activate, which controls instinctive reactions such as “fight or flight,” according to studies.

Our ticklish spots are found to be our weakest spots. Laughter derived from being tickled is thought to be a sign of submissiveness. Tickling also opens the Rolandic Operculum part of the brain that controls facial movements and vocal and emotional reactions. Hmm, that kind of explains nervous laughter.

You can't tickle yourself because there is no need for your brain to respond to defending yourself in anticipation of potential pain.
