神经元的功能主要由突触后膜、胞体膜和始段膜三种膜结构的不同活动特性决定的．根据这三种膜结构的电生理性质及其形态结构提出了一个比较精确的现实性动态神经网络模型．计算机仿真结果表明这个模型在具有比较简明的形式及较小的计算量的同时，能较全面地反映神经元的活动特性．通过与其他模型的比较，对神经元各部分的结构与其功能的关系有进一步的认识．
Neuronal function is mainly determined by the different activity characteristics of the three membrane structures of the postsynaptic membrane, the somatic membrane and the first segment membrane. According to the electrophysiological properties and morphological structure of the three membrane structures, a more accurate and realistic dynamic neural network model is proposed. Computer simulation results show that the model can reflect the activity characteristics of neurons more completely while having a more concise form and a smaller amount of computation. Through the comparison with other models, the relationship between the structure of each part of neurons and their function is further recognized.
