I did receive a reply from the Stough Institute on this matter. It agrees with Tony et al. I think. Here it is ". I do believe the diaphragm is part involuntary and part voluntary. What is most involuntary: The diaphragm is innervated directly by the phrenic nerve, which nerve does not innervate any other muscle but the diaphragm; so, the diaphragm has its own exclusive communication with the nervous system. The phrenic nerve fires its impulse to begin an inhalation in response to a change in blood gases that is monitored in the respiratory center of the brain (carbon dioxide rising above a certain point; oxygen descending below a certain point). That reflexive response of the phrenic nerve will happen automatically, without voluntary intervention, and will carry on automatically when, for example, we are asleep or paying attention to other subjects. This ongoingness of the breathing activity, I believe, is the most involuntary aspect. It keeps carrying out its assigned activity from the first breath to the last breath of one's lifetime.

However, on the voluntary side of the argument: The diaphragm is composed of striated muscle fibers, like all other voluntary muscles in the body. While we cannot completely stop it or start it, we can have partial voluntary influence upon its timing, speed of action and fullness of excursion. It is my belief that the initial impulse of the diaphragm sets the inhalation in motion, with an almost instantaneous response of the intercostal muscles to also begin the matching expansion of the ribcage. However, it is such a smooth and inseperable coordination, it is really difficult to tell which comes first (but my vote goes to the diaphragm for the initiation, because of the reflexive connection to the phrenic nerve."
With Tony's writing I haven't found he lists his sources of information. At least here we have something to show a scientific basis that is shared by other researchers. I don't regret questioning this particular point. No one came forth with any other sources. Why shouldn't one question it? Even this source notes "almost instantaneous response of the intercostals".
