You can call it communication if you want to.
Just like I can call a submarine moving through the water, swimming.
Yeah. Just like. Its as if each method of propulsion has its own story which, because it is a story, doesn't relate to other stories of propulsion. Communication covers thinking brings it under a common process makes a commonality among things like thinking, talking, integrated chemical activity - you know brings a suite of things into the discussion of common principles where we notice regularities, er, laws of nature - to the point where one set of principles, rather than millions, account for regularities in nature, where dualism is subsumed under determinism and life gets better.
