Figure 14. Bifurcation diagram showing the extrema of the mean of excitatory and inhibitory neuronal populations, PY and IN₁.

(a) The state transition diagram as the k₈ varying in [1.3, 1.7] with k₆ = 1.5, corresponding to the upward pink arrow in Fig. 13(a). The system transits from high saturated firing denoted by ‘I’ to clonic oscillations (II), SWD discharges (III), low saturated firing (IV) and to the simple tonic oscillation (V).
