Antidromically and synaptically activated spike and synaptic potentials in the nucleus reticularis tegmenti pontis (NRTP) of the cat were recorded intracellularly. The antidromic firing of the NRTP neurone is composed of IS-SD spikes with short duration and short spike-after-hyperpolarization. Membrane resistance and firing patterns were studied by applying depolarizing and hyperpolarizing current through the recording electrode. Findings indicate that the NRTP neurone has a relatively high membrane resistance and is capable of firing at a high frequency. Single shock stimulation of the interpositus (IP) and lateral nucleus (LN) of the cerebellum, brachium conjunctivum (BC), red nucleus (RN) and cerebral peduncle (CP) induced monosynaptic EPSPs in the NRTP neurones. Superior vestibular nucleus (SVN) stimulation induced monosynaptic IPSPs. Collision tests showed that (1) NRTP neurones are activated by the axons of IP and LN neurones which travel through BC, (2) these axons also send collaterals to RN, and (3) there is convergence of cerebellar, cerebral and brain stem inputs to a single NRTP neurone.
采用细胞内记录法记录了猫脑桥被盖网状核（NRTP）中经逆向和突触激活的锋电位和突触电位。NRTP神经元的逆向放电由持续时间短和锋电位后超极化短的IS-SD锋电位组成。通过记录电极施加去极化和超极化电流，研究了膜电阻和放电模式。结果表明，NRTP神经元具有相对较高的膜电阻，能够高频放电。对小脑间位核（IP）和外侧核（LN）、结合臂（BC）、红核（RN）和大脑脚（CP）进行单次电刺激，可在NRTP神经元中诱发单突触兴奋性突触后电位（EPSP）。刺激前庭上核（SVN）可诱发单突触抑制性突触后电位（IPSP）。碰撞试验表明：（1）NRTP神经元被经BC传导的IP和LN神经元的轴突激活；（2）这些轴突也向RN发出侧支；（3）小脑、大脑和脑干的输入汇聚到单个NRTP神经元。
