【摘要】 在Hindmarsh-Rose(HR)单神经元模型的基础上,结合视皮层的神经网络模型,研究分析视皮层中各神经元的发放模式。数值仿真显示:视皮层网络结构的各层中,神经元的发放具有同步现象;当双极细胞的外界刺激改变时,神经元出现簇发放和峰发放两类模式;随着外界刺激强度的增强,电位发放的峰峰间距(ISI)显示分岔现象。更多还原

【Abstract】 In this paper the Hindmarsh-Rose(HR) single neuron model was used to study the neuron spike pattern of visual cortex based on the neural network of the visual cortex.The simulation results showed that,in every layer of the visual network,the neuron spikes appeared synchronization phenomena.When the external stimulation of bipolar neurons was changed,the pattern of the neurons spike presented bursting and spiking.The ISI of potential spike showed bifurcation when increasing the stimulation intensity.更多还原
