[Contribution to the structure of respiration control].
A structure is reported which describes the relatively free availability of the motor respiratory apparatus to non-respiratory functions due to the presence of a respiratory control both on homeostatic and motor levels. It is assumed that, at the motor level, a competition develops of two or more regulators for the same parameter (e.g. the activity of neurons that can be claimed both by respiratory and by a second skeletal motor process). The compromise being reached is dependent on the amplification in the competing circuits. The correlation between the metabolic value and that of the respiration-time volume may be accomplished by the fact that amplification in the respiratory-motor circuit is rendered variable as a result of its interconnection with the chemical respiratory control. The high time constant of the latter allows for the instantaneous free availability of the motor respiratory apparatus to non-respiratory functions. The postulated structure offers better interpretations for the actual respiration behaviour than those considering the respiratory function alone.
