Abstract. The article discusses a memristive neuromorphic system consisting of two analog memristive neurons, Fitzhugh-Nagumo, connected through a memristive device Au/Zr/SiO2/TiN/Ti/SiO2/Si. Such a system, on one hand, imitates the biologically plausible dynamics of ion channels in neurons, and on the other hand, the interneuronal synaptic connections. It has been established that the memristive device, under the influence of a signal from the presynaptic electrical neuron, exhibits synaptic plasticity. Experimental results have shown forced synchronization modes with frequency ratios of 1:1, 2:1, N:1. The developed system effectively reproduces the dynamics of synaptic connections in neural networks of the brain. From an applied point of view, due to the adaptive properties of the memristor, it can be used for the development of neurosensory devices.

Key words: memristor, neuron, synapse, synchronization, neuromorphic system.
