I'm an American and I grew up using the word noggin. I've heard it said "that's using your noggin" from my parents and grandparents on both sides of the family. Noggin is slang for head or brain and almost anyone over 30 years old in America would think head or brain depending on the sentence, if you were to use the word noggin. Using "that's using your noggin" means you've done something good or figured out a problem. It's also a double slang or pun if you will, if some one were to use their head to break something or bumped his head, You might hear "that's using your noggin or head". Same if you injured your head, you might hear it as an insult because they didn't think before they did something and got hurt or hurt their head, (Well that was using your noggin). I'm guessing of course, but both sides of my family are from the Midwest of America Indiana,Kentucky or Tennessee around there in that area is where it most likely started, and it's just a saying using a slang word. I've also heard and used gourd, melon, airbag for head. Airbag is a more resent slang term. I guess more of a slander than the average term. The term noggin isn't heard much now days except by older folks being slightly comical or making friendly light hearted comments.
