...Harvard professor opened up a cat and beheld certain belly muscles tickling its heart. That was of such profound physiological import that the professor, Walter Bradford Cannon, a great physiologist, last week took train to Yale, which once gave him an honorary Doctor of Science degree, to tell the Yale Medical Society just what he had done, what he had seen, what it all meant...
Professor Cannon described his conclusive experiment. Using a cat, he severed all nerves connected with the heart, as well as all nerves connected with every organ which produces known hormones. He also cut the upper spinal cord transversely. The only nerves left intact were a few strands running from the spinal cord to the smooth muscle of the lower abdominal region. He then caused the fore part of the animal to struggle, and observed no change in the heart rate. After causing the hind part of the animal to struggle, however, he noticed a slow increase in the heart rate...
...Since the only tissue known to be affected by sympathetic stimulation in this region is smooth muscle," Dr. Cannon explained, "and since the only connection between the hind part of the animal is the blood stream, and since interfering with the stream in the region where smooth muscle is stimulated either markedly depresses or abolishes the response, the inferences are drawn that a substance is given off from smooth muscle into the blood, that it is carried effectively by the blood to distant organs, and that it influences those organs in a favorable manner, i.e., as sympathetic impulses would influence...
