Descartes came up with ____________. Based on ______________. - ANSWER-first modern model of nervous system; hydraulics What was Descartes thinking behind hydraulics model of nervous system? - ANSWER-The water would move to a joint and the water would move that joint and then the water would leave returning the joint back to its resting position.
