Our metaphors for the operation of the brain are…
““Our metaphors for the operation of the brain are frequently drawn from the production line. We think of the brain as a glorified sausage machine, taking in information from the senses, processing it and regurgitating it in a different form, as thoughts or actions. The digital computer reinforces this idea because it is quite explicitly a machine that does to information what a sausage machine does to pork. Indeed, the brain was the original inspiration and metaphor for the development of the digital computer, and early computers were often described as 'giant brains'. Unfortunately, neuroscientists have sometimes turned this analogy on its head, and based their models of brain function on the workings of the digital computer (for example by assuming that memory is separate and distinct from processing, as it is in a computer). This makes the whole metaphor dangerously self-reinforcing.””
