It Isn't Just the Nervous System

We're witnessing a revolutionary shift from nervous system supremacy to distributed intelligence – fascia as information highway, gut as neurotransmitter factory, immune cells as memory keepers. The systems involved in processing signals about your internal environment include not only the peripheral nervous system and central nervous system, but also the vascular, endocrine, and immune systems. We've known this for decades now, but the nervous system still gets all the hype. And that's too bad, because if what you want is a learning system, then you have much more to learn from the whole of things than from just one confined data source.
