Rats giggle too

Ten years ago when neuroscientist Jaak Panksepp published his research showing that rats laugh when you tickle them, he might have gotten laughed off the stage. Most people still thought that “sophisticated” emotions like laughter required the kind of consciousness that we associate only with humans. But Panksepp’s research is winning them over. Panksepp says,

Although some still regard laughter as a uniquely human trait, honed in the Pleistocene, the joke’s on them.

    What can I say? I’m tickled! Not at all surprised, though.

    I loved the joy captured in this video! It was amazing to me that a scientist could be so unambiguous about calling it laughter! Refreshing!

      Yes, there is quite a change taking place in the biological sciences when it comes to identifying feelings in other creatures. Thank goodness!
