The discharge in single‐ or few‐fibre chemoreceptor preparations from the aortic nerve of the cat has been measured, and plotted against the prevailing blood pressure. If the blood pressure is raised mechanically, the relation between these two variables differs from that found when the pressure is raised reflexly or by catechol amines. It is suggested that the sympathetic‐adrenal system may have a significant effect on the sensitivity of chemoreceptors.
