[Role of extravagal reflexes in regulating diaphragmatic excitation following tracheal occlusion and changes volume of the thoracic cavity in cats].
Decerebrated vagotomized cats after tracheal occlusion developed a slight but significant decrease in duration of inspiration, respiratory cycle, and in amplitude of diaphragmatic nerve ENG. Deflation (10-30 ml) or inflation (20-60 ml) of the lungs produced no changes in activity of diaphragmatic motorneurons. A stronger inflation (80-100 ml) decreased the expiratory phase activity. After bilateral vagotomy only slight and inconstant changes of respiratory rhythm were observed.
