Abstract
Statistical analyses are applied to records obtained under conditions of spontaneous activity. These demonstrate that all the cells examined are similar in the respect that their signals are composed of an approximately Poissonian shower gated on and off at random instants. A mathematical model is developed on this basis which characterises the signal of any one neurone with a number of simple parameters. The manner in which these parameters change under various types of stimulation is studied. It is found that the average frequency inside the sections of Poisson shower remains unchanged in all cases examined. Implications as to the types of network involved are discussed.
摘要
统计分析应用于在自发活动条件下获得的记录。这些分析表明，所有被检查的细胞在其信号由在随机时刻开启和关闭的近似泊松簇组成这方面是相似的。在此基础上建立了一个数学模型，该模型用一些简单参数来表征任何一个神经元的信号。研究了这些参数在各种类型刺激下的变化方式。发现在所有检查的情况下，泊松簇各部分内的平均频率保持不变。讨论了所涉及网络类型的相关含义。
