Here is a picture of Stephen Pinker with a model of the human brain. Pinker is an easy choice for Awesome Brain -- Awesome Hair. He's an evolutionary psychologist who knows more about brain function and language acquisition than just about anyone on the planet. And he wins the Harvard Faculty Hair Competition almost every year. If you want to know how the mind works, you might want to read Pinker's book, How the Mind Works.
Mr. Pinker is also Canadian.
