This study aimed to probe into occurrence and development of spontaneous firings in the telencephalon neurons of Hynobius leechi . [Method] Mi-croelectrode technique was used to record extracellular spontaneous electrical activi-ties of the telencephalon neurons of H. leechi in occurrence and development. [Re-sult] There were three discharge types in the occurrence of telencephalon in H. leechi , with single spontaneous firing and consecutive single spontaneous firing being main-ly apparent. And among the five types in the development of telencephalon, the main discharge type was single spontaneous firing. Along with the occurrence and development of telencephalon, the extracellular discharge intensity enhanced gradual-ly, the discharge duration increased, and the spontaneous firing frequency accelerat-ed, al of which reached the maximum in the adult phase. Fol owing the process of occurrence and development, other discharge types appeared successively. [Conclu-sion] Along with the occurrence and development of the telencephalon in H. leechi , the neuronal excitability increases step by step and the neuronal electrical activities diversify gradual y. 展开更多
