The effects of stimulation of the vestibular nerve and of regions in and around the vestibular nuclei on long C3-C5 propriospinal neurones (PNs) were investigated with intracellular recording. Disynaptic excitatory postsynaptic potentials were evoked from the contralateral (co) or ipsilateral (i) vestibular nerve in many long PNs but mainly in crossed PNs from the co and in uncrossed from the i nerve. Disynaptic inhibitory postsynaptic potentials were evoked more rarely, mainly from the i vestibular nerve. Threshold mapping revealed an excitatory relay from the co nerve in the medial vestibular nucleus (MVN) and also that the excitatory MVN neurones projecting to the long PNs send collaterals to the abducens and interstitial nucleus of Cajal. Excitation from the i vestibular nerve was relayed in the lateral vestibular nucleus (LVN) and in the MVN. Also, non-second order LVN neurones project to the long PNs. Monosynaptic IPSPs were evoked from the i MVN and i LVN.
采用细胞内记录法研究了前庭神经及前庭核及其周围区域的刺激对长C3 - C5脊髓 propriospinal 神经元（PNs）的影响。在许多长PNs中，尤其是来自对侧（co）的交叉PNs和来自同侧（i）神经的非交叉PNs中，可从对侧（co）或同侧（i）前庭神经诱发双突触兴奋性突触后电位。双突触抑制性突触后电位诱发较少，主要来自同侧前庭神经。阈值映射显示在内侧前庭核（MVN）中存在来自对侧神经的兴奋性中继，并且投射到长PNs的兴奋性MVN神经元向展神经核和 Cajal 间质核发送侧支。来自同侧前庭神经的兴奋在前庭外侧核（LVN）和内侧前庭核（MVN）中中继。此外，非二级LVN神经元投射到长PNs。可从同侧MVN和同侧LVN诱发单突触IPSPs。
