Rotation control of an HR neuron with a locally active memristor

When a locally active memristor is applied to the Hindmarsh-Rose neuron, complex neuromorphological dynamics can be observed. Local active memristor leads to neuromorphological oscillation giving various neuron spiking. The rotation control is applied to explore the chaotic bursting. It is found that the amplitude of the neuron bursting changes regularly according to the angle of rotating without dynamics switching. The rotation control is compared with the offset boosting showing the complete control of spiking under selected rotation. The design of the rotation control matrix is the fundamental factor for amplitude control, which does not revise the Lyapunov exponents but only leaves a suitable amplitude and offset modification.

Automated summary

In this study, the complex neuromorphological dynamics observed when a locally active memristor is applied to the Hindmarsh-Rose neuron are discussed. The results show that the rotation control can effectively influence the amplitude of neuron bursting without causing dynamics switching. The design of the rotation control matrix is found to be crucial for amplitude control.
