I confess that my usual perspective on the nervous system is from outside in - I consider what happens when I put my hand on someone else's body part, and consider ensuing movement output as a consequence, as a nervous system's direct response.. there's almost always that idea of my inputting some sort of talented (or not) sensory input - first. That's how my treatment brain works - it uses the "operator"/"interactor" model, by default, usually, and my conceptualizations end up being informed by it.
I've been away from clinical work for over 4 months now, and my brain is learning to think in different ways. So, when I think of "movement" now, I'm seeing it in more abstract terms. Lately several papers and blogposts about movement have come to my attention. I don't know how they synthesize, yet.. but I'm paying attention to the process, at least. I'd like to outline a few thoughts about them, bearing in mind the role of the brain as predictor, oscillator, simulator. First though, I'm going to just link them here.
