Distributions of the excited state at (a)t= 1000000, (b)t= 1800000, (c)t= 4500000, and (d)t= 10000000, where the black represents the excited state, and the white represents the rest and refractory state. Panel (e) shows the orbit of the spiral tip in theydirection. Here,R= 3,K= 6,K1= 3,K2= 5,P= 0.01.
