Our most ticklish parts are coincidentally our weakest spots, such as our neck or our stomach, and so the team at Tuebingen theorize that parents would have tickled their offspring to train them to react to danger and that the laughter of tickling is an acknowledgement of defeat.Using 30 volunteers and hooking them up to MRI scanners, the researchers original questions was to work out why tickling elicits laughter and is that the same as laughing at a joke or a funny situation.
“Play behaviour (rat chasing experimenter’s hand) also evoked USVs.” A video of one such encounter also showed the rat making “joy jumps” during the tickling.
Sanderson appeared at Edinburgh Sheriff Court last Tuesday, where he was remanded in custody after admitting the charges against him.
He will be sentenced at the city court this coming Wednesday.
According to scientists at the University of Tuebingen, 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.
Furthermore, 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.
