Changes in frequency of tonic impulses in efferent sympathetic fibers of the left splanchnic nerve on stimulation (10 V, 10--20 Hz, 1 ms) of afferent fibers of the right splanchnic nerve and of both trunks of the vagus nerve at the cervical and abdominal levels have been studied in experiments on cats. It is established that there are sympatho-inhibitory and sympatho-activatory fibers whose quantitative correlation is different in various trunks. Sympatho-inhibitory influencies are most marked on stimulation of vagus nerve ventral branch and sympatho-activatory ones on stimulation of right splanchnic nerve. At the cervical level, in vagal left trunk sympatho-inhibitory fibers preponderate but in the right one another correlation occurs. In abdominal cavity the distribution of both types of fibers appears to have organ principle. Fibers innervating stomach have sympatho-inhibitory action but those innervating small intestine--sympatho-activatory. This suggests the hypothesis about the role of these fibers in digestion regulation. The central cholinolytic amysil abolishes sympatho-inhibitory effects but not sympatho-activatory ones.
在猫的实验中，研究了刺激右侧内脏神经的传入纤维以及颈段和腹段迷走神经的两个主干（10伏，10 - 20赫兹，1毫秒）时，左侧内脏神经传出交感纤维中紧张性冲动频率的变化。已确定存在交感抑制纤维和交感激活纤维，其数量相关性在不同主干中有所不同。刺激迷走神经腹支时交感抑制影响最为明显，刺激右侧内脏神经时交感激活影响最为明显。在颈段，迷走神经左主干中交感抑制纤维占优势，但在右主干中则出现另一种相关性。在腹腔中，这两种纤维的分布似乎遵循器官原则。支配胃的纤维具有交感抑制作用，而支配小肠的纤维具有交感激活作用。这提示了关于这些纤维在消化调节中作用的假说。中枢性胆碱解酶阿密西平消除了交感抑制作用，但未消除交感激活作用。
