Why do you laugh when you’re tickled? Scientists at Humboldt University of Berlin are studying rats to try and solve the longstanding mystery. Given the right conditions, and enough back and belly tickling by a researcher, ratscan come to associate a researcher’s cotton gloved hand with the sensation of being tickled. Tickling makes them “giggle,” albeit in frequencies too high for human ears to hear. The rats develop a fondness for the human hands, chasing their scurrying fingers in circles. The scientists observe the rat ticklishness, and track how their brain processes the sensation, hoping to uncover clues about the laugh-inducing feeling.

    I like rats, never understood the fear and hate of rats, for me they are little furred humans,

    When I capture on in my house even when they destroy something I just throw them outside and forget about it

    that tickling is way too rough, that's how you would tickle a human and not a tiny rodent.
