Ever since the days of Alan Turing, neuroscientists have, in increasing numbers, compared the human brain to a computer. It's an analogy that makes a hell of a lot of sense, and it's done much to help us understand this remarkable grey blob that sits between our ears. But as a recent essay by philosopher Daniel Dennett points out, while the brain should most certainly be considered a kind of machine — one with a trillion moving parts — its inner workings are far removed from anything we have ever developed. Consequently, scientists need to take note and update their models accordingly. Calling the brain a "computer," says Dennett, is accurate, but insufficient.
