@reasoning logic,
How do you think you wrote that post if not by sending electrical impulses and chemical messages (neurotransmitters) through your nervous system?
You can control your actions. You do it all the time, we can translate our wishes and ideas into acts, like commit ideas to paper or keyboard,
through some sort of control system that passes EVIDENTLY through the nervous system. Ergo ideas can have control over nerves.
Which does not mean nerves can't have some control over ideas... It's probably a dialogue, a constant flow between one and the other. An homomorphic relation for instance.
