The study concerns the effects obtained at the medulla by electrical stimulation of mechanoreceptive afferences associated to the hyomandibularis nerve and branches of V and VII cranial nerves of the frog. Each of the afferences examined activates both nuclei of XI and XII in spite of the different medullary input; this action is very similar to that carried out by the mechanoreceptor afferences coming from papillae fungiformes. These result show very well the common ability of all the afferences coming from the mouth to obtain a similar action at the medulla. These properties suggest a convergence of the oral mechanoreceptor information on a mechanism of integration in order to obtain a coordination of the tongue and oesophagus motor reflex.
该研究关注通过电刺激与青蛙的舌颌神经以及第V和第VII对脑神经分支相关的机械感受器传入纤维，在延髓所获得的效应。尽管延髓的输入不同，但所检查的每一种传入纤维都能激活第XI和第XII对神经核；这种作用与来自菌状乳头的机械感受器传入纤维所产生的作用非常相似。这些结果很好地表明，来自口腔的所有传入纤维都具有在延髓产生类似作用的共同能力。这些特性表明，口腔机械感受器信息汇聚于一种整合机制，以便实现舌和食管运动反射的协调。
