I've read tons of articles about how moving our bodies is going on. BUT I've found some part of topic just IGNORED. ALL authors just pass the part "our brain generates the signal". I have been trying to find the answer for 1 week and found nothing.
Is it an unanswered question in neuroscience? Or they just skip because they don't know, or it is so trivial question and only I cannot understand it?
Because in order to depolarize the neuron it should open ion channels by our wish. E.g. I wanna move my leg up, just because I can. My brain opens ion channels just because I want it. My will should be like physical power isn't it?
