S ummary Evoked potentials to the splanchnic stimulation were recorded from the ipsi‐lateral posterior funiculus and from the bilateral anterolateral funiculi in the spinal cord. The former had a short latency and the latter had a long latency. Evoked potentials of the splanchnic nerve were recorded from the nucleus cuneatus and lemniscus medialis in the medulla, which had a short latency since their origin was in the impulses ascended through the posterior funiculus of the spinal cord. Evoked potentials were also recorded from the tractus spino‐m‐thalamicus and nucleus reticularis ventralis in the medulla, which had a long latency corresponding with those from the anterolateral funiculi of the spinal cord. The splanchnic impulse, ascended through the anterolateral funiculus of the spinal cord, was influenced by the effect of the vagal stimulation as well as the stimulation of the somatosensory and proprioceptive systems through mediation of the activity of the brain stem reticular formation. The vagal stimulation also exerted an inhibitory effect on the splanchnic afferent impulse in the anterolateral funiculus through some other mechanism than mediation of the brain stem reticular formation.
