Activity was recorded from 188 vagal efferent fibres, 90% of which showed responses to distension of the stomach and duodenum. Of thirty fibres tested with single-shock vagal stimulation, reflex action potentials were evoked in fifteen, ranging in latency from 39 to 318 ms. Responses at short latency showed little latency-jitter and high response-probability, and those at long latency showed opposite characteristics. This suggests that two pathways are present in the central organization of vagal reflexes to the gut.
记录了188条迷走神经传出纤维的活动，其中90%的纤维对胃和十二指肠扩张有反应。在用单次迷走神经刺激测试的30条纤维中，15条诱发了反射动作电位，潜伏期在39至318毫秒之间。短潜伏期的反应潜伏期抖动小，反应概率高，而长潜伏期的反应则表现出相反的特征。这表明在迷走神经对肠道的反射中枢组织中存在两条通路。
