A dependence of the activity of the aortic baroceptors on the aortic pressure in stimulation of a branch of the stellate ganglion innervating the aortic baroceptor zone was studied in experiments on cats. The sympathetic stimulation failed to change the threshold of baroceptors (80 mm Hg) and their activity within the pressure range of 80-140 mm Hg. With higher aortic pressure the sympathetic stimulation decreased the baroceptor activity. As a result, an increase of the baroceptor activity with pressure was less and maximal activity was attained at higher aortic pressure (greater by an average of 32 mm Hg). The action mechanism of the influence of the sympathetic innervation on the baroceptor sensitivity, and physiological significance of this phenomenon are discussed.
在猫身上进行的实验中，研究了在刺激支配主动脉压力感受器区域的星状神经节分支时，主动脉压力感受器的活动对主动脉压力的依赖性。交感神经刺激未能改变压力感受器的阈值（80毫米汞柱）及其在80 - 140毫米汞柱压力范围内的活动。当主动脉压力较高时，交感神经刺激会降低压力感受器的活动。结果，压力感受器活动随压力的增加变小，并且在较高的主动脉压力下达到最大活动（平均高32毫米汞柱）。讨论了交感神经支配对压力感受器敏感性影响的作用机制以及这一现象的生理意义。
