1.在正常大鼠和出生时用辣椒素处理的大鼠中检查了远端回肠的传入神经支配。电生理记录使用在体外制备的远端回肠及其相关的肠系膜神经。肠系膜神经的纤维组成进行了检查，通过电子显微镜和数量的初级传入纤维支配的一段远端回肠估计使用逆行追踪。2.记录了120个单一的传入单位，所有这些单位都表现出一定程度的背景活动。对67个传入单位的传导速度进行了估计，发现所有单位的传导速度都在C纤维范围内（
1. The afferent innervation of the distal ileum has been examined in normal rats and in rats treated at birth with capsaicin. Electrophysiological recordings were made using an in vitro preparation of distal ileum and its associated mesenteric nerves. The fibre composition of the mesenteric nerves was examined by electron microscopy and the numbers of primary afferent fibres innervating a segment of distal ileum was estimated using retrograde tracing. 2. Recordings were made from 120 single afferent units all of which showed some degree of background activity. The conduction velocities of sixty-seven afferent units were estimated, and all were found to be in the C-fibre range (
