JAMES NYE, ’Why being tickled is NOT funny: Sensation activates part of the brain that copes with pain’, http://www.dailymail.co.uk/news/article-2331500/Researchers-discover-laugh-tickled–answer-funny.html, MailOnline, Daily Mail (27 May 2013)


Tickling activates the part of our brain that anticipates pain – which is why you may accidentally lash out at someone who is trying to tickle you. (…) The laughter from being tickled is part of a defense mechanism to signal submissiveness and the researchers believe that our responses to tickling date back to man’s earliest evolution and developing self-awareness. (…) Scientists discoveries cast new light on why some people even start to laugh just with the threat of being tickled.
