From: Exploring the geometry of the bifurcation sets in parameter space
Spike-counting sweeping technique of the Hindmarsh–Rose system (1) in the parameter plane (b, I), with \(\epsilon = 0.018\) (subplot (a)), 0.03 (b) and 0.08 (c). The color indicates the number of spikes per period, increasing from blue (0 spikes) to brown (the maximum value associated with chaotic behavior). Bifurcations: Homoclinic and period-doubling codimension-1 curves; orbit-flip (OF), inclination-flip (IF) and Belyakov codimension-2 points.
