两栖类交感神经节的突触传递

Xynaptic transmission of amphibial sympathetic ganglions

两栖类交感神经节广泛地用于神经生物学研究，包括突触和膜生物物理学研究．交感神经节细胞体积大，细胞的形状简单，无树突，突触位于细胞体上，神经节结构简单，但同时又具有中间神经元，在体外易于长时间存活．两栖动物交感神经节表现出多种突触后电位，包括快兴奋性突触后电位（ｆＥＰＳＰ），慢抑制性突触后电位（ｓＩＰＳＰ），慢兴奋性突触后电位（ｓＥＰＳＰ），晚期慢兴奋性突触后电位（ｌｓＥＰＳＰ），同时还表现多种突触塑性，说明该神经节具有信息存储功能，因此，两栖动物交感神经节可作为研究学习与记忆的模型系统．

Amphibial Sympathetic ganglions are used broadly in the study of neurobiology including membrane and biophysics. Sympathetic ganglion cells have large Volume, simple shape no dendron and synapses on the cell body. Cellular structure is simple and has intermediate neurons, which can survive a longer period in vitro. Amphibial sympathetic ganglions show various postsynaptic potential including fast excitatory postsynaptic potential (fEPSP). Slow inhibitory postsynaptic potential(sIPSP).Slow exeitatory postsynaptic potential (sEPSP). late slow excitatory postsynaptic potential (lsEPSP) and Various Synapse plasticity the Sametime, these Suggust the ganglions have message collection function. Therefore, amphibial sympathetic ganglions can act as model system for strding and memory researches.
