[Dynamics of the respiratory center activity during electrical stimulation of the diaphragmatic nerve].
The adoption of artificial rhythm of electrical stimulation of diaphragmatic nerve was found to be determined by the force and rate of artificial contractions of the diaphragm, by the concentration of barbiturates in the blood and by gaseous composition of inspired air in anesthetized dogs. The time interval between the onset of artificial contraction and onset of natural one seems to characterize functional activity of respiratory center and to result from inhibitory afferent effect of the lungs' mechanoreceptors, on the one hand, and from activating effects of central and peripheral chemoreceptors, on the other hand.
