The Hindmarsh-Rose (HR) model [5] is computationally simple and 46 3 A Gallery of Chaotic Circuits Fig. 21 Experimental results of the Lorenz circuit: chaotic attractor shown by the implemented circuit. Phase plane: X –Z . Horizontal axis = 200 mV/div, vertical axis = 500 mV/div capable of reproducing rich firing patterns exhibited by real biological neurons. It consists of three coupled ordinary differential equations that, as a function of the parameter values, can generate different spiking and bursting behaviors, including chaotic spiking.

The trend of the three-state variables x, y, and z and the corresponding attractor are shown in Figs. 2. 1 The Jerk Circuit 35 Fig. 3). Components: D = 1N4148 Diode, R1 = 1 kπ, R2 = 1 kπ, R3 = 1 kπ, R4 = 1 kπ, R5 = 1 kπ, R6 = 1 kπ, C1 = 1 µF, C2 = 1 µF, C3 = 1 µF, Operational Amplifier = TL084, Vcc = 9 V As it can be noticed, all the three variables oscillate in a range which is compatible with a voltage power supply fixed to ±9 V, so the variables do not need to be scaled. The second step of the procedure involves the design and circuit simulation of the electronic system.
