The sensory innervation of the small intestine was studied in the cat with electrophysiological, histological and histochemical techniques. Thanks to the histochemical technique (peroxydase method) the exact number and proportion of splanchnic and vagal fibres was determined : the latter being about 9 times more numerous than the former. On the other hand the exact position of the corresponding cells was defined in the nodose and spinal ganglia by means of the previous technique and the microelectrophysiological method (recording of single units into the ganglia with extracellular glass microelectrodes). The splanchnic neurones were found in the T9, T10 and T11 ganglia whereas the vagal ones were chiefly located in the lower half of the nodose ganglia. The histological studies using electronic microscope showed many non-medullated endings, which were often found beneath the epithelium and in the lamina propria of the villi close to the blood vessels. This result is certainly the proof that numerous receptors (mechanoreceptors, chemoreceptors and even thermoreceptors do exist in the small intestine.
采用电生理、组织学和组织化学技术对猫小肠的感觉神经支配进行了研究。借助组织化学技术（过氧化物酶法）确定了内脏神经纤维和迷走神经纤维的确切数量及比例：后者数量约为前者的9倍。另一方面，通过先前的技术和微电生理方法（用细胞外玻璃微电极记录神经节中的单个单位）确定了相应细胞在结节神经节和脊髓神经节中的确切位置。在内脏大神经节T9、T10和T11中发现了内脏神经元，而迷走神经神经元主要位于结节神经节的下半部。使用电子显微镜的组织学研究显示有许多无髓神经末梢，这些末梢常在绒毛上皮下方和固有层靠近血管处发现。这一结果无疑证明小肠中确实存在大量受体（机械感受器、化学感受器甚至温度感受器）。
