The next development emerged from ancient Greece from philosophers Aristotle, Plato and Almaceon. The ancient Greeks hypothesized the form and function of the mind, psyche and soul. Aristotle’s theory focused on the heart as the seat of the mind. He saw the heart containing all emotion and thinking. He also thought that the brain functioned to cool the heart down. Unlike Aristotle, Plato believed the brain to be the locale for mental processes. With Aristotle we see the emergence of the dualistic view of mind and body. The dualistic versus monistic approach to the mind and brain is a debate dominating much of the history of cognitive neuroscience.
