[The effect of rapid changes in lung volume on the postinspiratory phase of the respiratory cycle in decerebrate cats].

In decerebrated cats, fast blowing of the lungs decreased the duration of inspiration, the amplitude of the diaphragmatic nerve ENG, and increased the duration of the second phase of expiration. The duration of postinspiratory phase was increased in proportion to changes in lung volume. Bilateral vagotomy induced a complete disappearance of the reflex responses.
