What's So Funny?

Delve into a comedian's brain to discover what makes people laugh -- and when the comic is also a neuroscientist, it's no joke! Dr.  Ori Amir  studies what goes on in the brain as jokes are born, and he's also learned how to "get out of his head" to write some pretty funny stuff. Be afraid: He is working on using artificial intelligence to come up with new puns to make us groan.
