Jaak Panksepp's rat-tickling experiments challenged the belief that emotions depend solely on the human cerebral cortex. The findings suggest that joy and play engage primitive brain regions and dopamine systems shared across species.
- Rats produced joyful sounds while being tickled and playing
- The discovery challenged the idea that only humans experience emotions
- Joy appears rooted in ancient brain regions
- Play releases dopamine and supports engagement
“Joy, Panxep showed, is a deeply primal experience.”
