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?

  • $\begingroup$ Wanting to move, thinking about moving, all your wants and desires and motivations are all brain activity. You don't open ion channels because you want them open, you want things because ion channels opened. $\endgroup$

  • $\begingroup$ @BryanKrause, okay. I moved leg up, I can move it, I can leave it, it is fully controlled process now. Someone else can tell me to move my leg. In case if all of them are already opened channels we wouldn't have control over them, isn't it? $\endgroup$

  • $\begingroup$ I'm simplifying to the extreme. It's of course not only "channels opening" but activity in populations of cells that in turn influence other populations and themselves. The point is that you cannot separate your thoughts from your neural activity. They are the same thing. $\endgroup$

  • $\begingroup$ @BryanKrause, sure, I didn't separate. I want to know, how abstract "desire" (will, or wish) can be converted to PHYSICAL power whatever it is: opening ion channels, generating transmitters, put these transmitters into some exact neurons. Because I decide to move my arm, completely by my desire, it's not a reaction to any external things. Okay, putting it in another manner: how abstract things are created without any input reasons? $\endgroup$

  • $\begingroup$ And I'm telling you: those desires and abstract thoughts are not materially different from other types of neural activity evoked by a stimulus. The physical power comes when those signals are sent to muscles. $\endgroup$
