植物神经节中的非胆碱能性兴奋性突触电位或称迟慢兴奋性突触电位(Is-EPSP)在不同物种及不同神经节标本中已报导有不同的相关递质;它们包括P物质,5-羟色胺和促性腺素释放激素(LHRH)。目前两栖类的研究资料均来源于牛蛙的樵旁神经节。为此我们将观察扩展到蟾蜍(Bufo Bufo 300只)和少量青蛙(Rana Nigromaculata,30只)。用离体第八或第九椎旁神经节作细胞内电位记录。第七脊神经及同水平的交感链作节前神经刺激处。串刺激(2—30Hz,5s超最大强度)引起一串快兴奋性
Non-cholinergic excitatory synaptic potentials, or slow-acting excitatory synaptic potentials (Is-EPSPs) in autonomic ganglia, have reported different related neurotransmitters in different species and in different ganglion specimens; they include P Substance, serotonin and gonadotropin-releasing hormone (LHRH). The amphibian research data are derived from the bullfrog woodside para ganglion. To this end, we expanded the observation to Toad (Bufo Bufo 300) and a few Frogs (Rana Nigromaculata, 30). In vitro eighth or ninth paravertebral ganglion for intracellular potential recording. The seventh spinal nerve and sympathetic chain with the same level for preganglionic nerve stimulation. Skeletal stimulation (2-30Hz, 5s maximal intensity) causes a burst of fast excitability
