Bifurcation diagrams: the extrema of the simulated EEG y and the corresponding transitions of dominant frequency. (a) The dynamics transitions of the system over changes in ctr with cte = 3. (b) The dynamics transitions of the system over changes in cte with ctr = 0.15. The transitions of states include HS, m-SWD, LS, CO, and TO, where m can be 1, 2, …, 6.
