不同突触的神经元网络同步放电比较研究

该文提出一种在刺激信号下突触类型对具有生物属性的神经元网络同步放电特性影响的模拟仿真方法。采取HH神经元模型和电突触、化学突触模型,利用数值模拟的方法,比较研究电突触和化学突触连接的生物神经元网络同步放电特性。在相同刺激信号下,电突触和化学突触连接的相同拓扑结构的神经元网络表现出不同的同步放电特性。在同一刺激信号,相同拓扑结构的神经元网络中,化学突触连接的网络同步放电特性要优于电突触连接的神经元网络。同时突触类型的不同可能会改变神经信息的编码方式,但不会改变信息传递的可靠性。

To propose a simulation method for the effect of synaptic types on the synchronous discharge characteristics of biological neural networks under stimulation signals.Using HH neuron model,electrical synapse and chemical synapse model,the characteristics of synchronous discharge of biological neuron network connected by electrical synapse and chemical synapse were compared and studied by numerical simulation.Under the same stimulation signal,the neural network with the same topology connected by electrical synapse and chemical synapse showed different synchronous discharge characteristics.In the neural network with the same stimulation signal and the same topology,the synchronous discharge characteristics of chemical synaptic connection are better than that of electrical synaptic connection.At the same time,different synaptic types may change the encoding of neural information but will not change the reliability of information transmission.
