一种更精确的现实性动态神经网络模型

A more accurate simplyfing realistic dynamic neural network model

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．

The membrane of a neuron is mainly composed of the following three parts:the postsynaptic membrane,the somatic membrane and the membrane of the initial segment. And it is the activities of the three parts that determine the function of a neuron. From this point of view,a new realistic dynamic neural network model is proposed with some simplified methods being adopted. A software has been written to simulate the activities of the model. The results of simulation show that the model can simulate the activities of neuron with relatively little expense of CPU time. More understanding about the relation between the structure and the function of neurons has been achieved by comparing our model with several other models.
