ABSTRACT
In some ways the authors could say that when they look at pictures of neuronal networks of a human brain, they see a tiny bit of the knowledge the brain once had in its physical form. Any change in knowledge must come from some change in neuronal networks Although he may not have realized it, Ausubel made a profound biological statement when he staked out prior knowledge as the beginning of teaching in the quote at the beginning of this chapter. He will develop three important ideas about prior knowledge in what follows. The picture he just described shows a network of four neurons, and it illustrates what he mean when he speak of neuronal networks. When the authors come to the brain and the actual neuronal networks found there, the numbers of connections, and the tangle of neurons, is truly incomprehensible.
