摘要

由纳米级忆阻器组成的仿生神经元振荡电路可以实现生物系统的大连接和高并行处理能力。忆阻器也有可能重现生物突触的行为。就像在生物中,突触的重量是由通过它的离子流动来调节的,所以忆阻器的电导率是由通过它的通量或电荷来控制的。为了指出忆阻器在生物突触中的作用,我们重点研究了一个由两个FitzHugh-Nagumo (FHN)神经元通过忆阻器耦合组成的简单仿生网络。特别地,我们研究了忆阻器的动态如何影响神经元之间的相互作用及其同步。

Synchronization in networks of FitzHugh-Nagumo neurons with memristor synapses
Networks made up of bio-inspired neuron oscillatory circuits with nanoscale memristors may achieve the large connectivity and highly parallel processing power of biological systems. Memristor also has potential to reproduce the behavior of a biological synapse. As in a living creature the weight of a synapse is adapted by ionic flow through it, so the conductance of a memristor is controlled by flux across or charge through it. In order to point out the role of memristor as biological synapse, we focus on a simple bio-inspired network composed of two FitzHugh-Nagumo (FHN) neurons coupled via a memristor. In particular, we investigate how the dynamics of memristor can influence the interactions among neurons and their synchronization.
