摘要
神经网络的宏观活动是由多个神经元电活动的叠加决定,神经元电活动的研究对深入理解神经网络工作机制和生理行为具有重要意义。本文采用Chay模型,对神经元电活动进行Simulink仿真研究,通过施加包括恒值、阶跃、脉冲、随机噪声等不同类型的输入,观察系统的输出响应。仿真结果符合通常的生理认识,有助于加深对神经元电活动和神经网络生理机制的理解。
Macro activity of neural network is determined by the superposition of a great deal of neuron electrical activity. The study of electrical activity to single neuron has great significance to understand more about the network working mechanisms and physiological behaviors. In this paper,the Chay model is adopted to describe the neuron electrical activity,and is created and simulated by simulink. The different inputs,including const, step,impulse and random noise,are feeding to the model separately to observe the response of the system. The simulation result is consistent with the general physiological understanding,and it will help to understand deeply the neuron electrical activity and the physiological mechanism of neural networks.
