Abstract

To study the synchronized oscillations among distant neurons in the visual cortex, we analyzed the synchronization between two modules of pulse neural networks using the phase response function. It was found that the intermodule connections from excitatory to excitatory ensembles tend to stabilize the antiphase synchronization and that the intermodule connections from excitatory to inhibitory ensembles tend to stabilize the in-phase synchronization. It was also found that the intermodule synchronization was more noticeable when the inner-module synchronization was weak.

摘要

为了研究视觉皮层中远距离神经元之间的同步振荡，我们使用相位响应函数分析了脉冲神经网络两个模块之间的同步性。研究发现，从兴奋性神经元集群到兴奋性神经元集群的模块间连接倾向于稳定反相同步，而从兴奋性神经元集群到抑制性神经元集群的模块间连接倾向于稳定同相同步。还发现，当模块内同步较弱时，模块间同步更为明显。
