Abstract:

Memristors can be introduced into neural networks for convenient chaos generation even combined with regulating firing activities. This article presents a no-equilibrium memristive ring neural network with dual memristors, one of which is used to mimic neural synapses and the other to describe the effects of external electromagnetic radiation. Initial conditions of different variables bring the chance to arise bistability and tristability. Initial offset-boosted coexisting hidden attractors are arranged by offset boosting, where homogeneous and heterogeneous multistabilities are captured simultaneously. When homogeneous attractors break barriers and connect together, the growth of attractors becomes apparent, allowing for flexible regulation over time and effective self-reproduction through varying initial values. Interestingly, abundant hidden firing patterns are well regulated by memristor-related parameters or the external current. Bursting and spiking firings are switched flexibly by proper knobs. In addition, infinitely many coexisting bursting and spiking firing patterns are also triggered by the initial values of the memristor acting as the coupled synapse or considered as an external electromagnetic radiation. Finally, a digital circuit based on CH32 is constructed to verify the characteristics of various coexisting hidden attractors and abundant firing patterns, thus confirming these new findings.
