Neural control of breathing: a system analysis.
A model of the neural control of quiet breathing in an anaesthetised and tracheostomised laboratory animal is presented. The loop consisting of the brain generator with its respiratory "master function", the phrenic command, the aerodynamics of the lungs and the volume information carried by the vagus nerves is described in mathematical terms. Computer model experiments are presented and compared with corresponding physiological situations. The stability of the model is demonstrated.
