Three-Dimensional Memristive Hindmarsh–Rose Neuron Model with Hidden Coexisting Asymmetric Behaviors

Figure 13

Experimentally measured phase portraits in the plane for hidden coexisting asymmetric attractors under different circuit parameters. (a) = 10 kΩ and = 1.36 kΩ. (b) = 10 kΩ and = 1.23 kΩ. (c) = 8.70 kΩ and = 1.11 kΩ. (d) = 6.17 kΩ and = 1.11 kΩ.
