Fig 5. Multiple synchronous behaviors and coexistence of firing patterns.
The numbers 3, 4, 5, 6, and 7 represent burst with 3, 4, 5, 6, and 7 spikes, respectively. BQ, MQ, and EQ lying between two dashed lines represent the beginning, middle, and end of the quiescent state of period-6 bursting (bursting pattern of isolated neuron), respectively. (a) The dependence of S max on both g 2 and τ; (b) the dependence of S max on both g 2 and τ with initial values different from those of Fig (a); (c) the dependence of S max on τ when g 1 = 0.6 nS and g 2 = 0.9 nS. The dotted (solid) line corresponds to initial values of Fig 5(a) (Fig 5(b)).
