Do you experience 'thinking' as happening inside your head?

Some people may scratch their heads when pondering, but I've never seen this behavior. However, when I'm thinking, or trying to, I feel the effort between my ears.



Do I experience it that way because of the knowledge we've accumulated about the brain? Would a caveman likewise identify thoughts as arising from the mind?
