Jaak Panksepp is a neuroscientist who has a play research centre at Washington State University.
He describes play-related "processes that link brain stem (movement) to limbic (emotional) to cortex (thought)” – ie, what the non neuroscientists among us might call processes that link body, heart and head. P62
We spend a lot of time in our heads. Well, I do.
My friend Anthea loves rock climbing as the only thing she can do with her clothes on that gets her "out of her head."
I always think of play as something that balances the heart, body and head. I like it for that.
