How does the action potential for voluntary actions initiate in the brain?

Question

I don't mean the responses to external stimuli. I mean when we think we want to do something and do it, how does the action potential start?

Answer 1

Your "thought" of movement starts in the precentral gyrus, the signal travels to the cerebellum via pontine nuclei, then the action potential is sent, but it is sloppy movement and still needs calibration. This is done after afferent signals from the proprioceptive neurons combine with the first set of efferents and the 2 are compared. The signals then are refined by the precentral gyrus and secondary impusles for the same movement are again sent down the pathway.
