Summary
Action potentials in the vagi of cats and rabbits were recorded to determine the effect of an artificial pneumothorax on pulmonary receptors and the respiratory center. It was found that there was a reduction in the impulses in the vagal fibers connected to pulmonary stretch receptors. The effect was to cause an increase in the activity of the respiratory center, which was shown at first by an increased number of efferent impulses at inspiration, and then an increase also in the impulses in the recurrent branch at expiration. It was also shown that the pneumothorax affected the cardiac receptors, and changed the frequency of the impulses which were grouped at the pulse rhythm.
