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. He believed that the brain thought about where the water should go and then it would go there. To him the spinal cord was just a tube, not a central...

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. He believed that the brain thought about where the water should go and then it would go there. To him the spinal cord was just a tube, not a central player in the movements. Descartes model caused three things to occur: - ANSWER-1. firmly separated mind and body, allo...
