Hindmarsh-Rose neuron

A 3-variable model of bursting and spiking neuron activity. Reproduces the chaotic firing patterns observed in real neurons.

Hindmarsh-Rose neuron in chaotic bursting regime (I = 3.25).

Equations

dx/dt = y − a x³ + b x² − z + I
dy/dt = c − d x² − y
dz/dt = r (s (x − x_R) − z)
