Endless brain gears

A visual tour of the clichéd 'cogs in the brain' image that seems to get attached to virtually every psychology article that isn't published in a women's magazine.

I'd be genuinely fascinated to know when this visual analogy first arose as you'd guess it's a result of the computational model of the mind that arose with 50?s cognitive science.

But you never know (at least, not without a stiff dose of machine oil).
