Figure 5. Three different regimes of steady state activity are attractors of a tristable model – two distinct silent states coexist with bursting.

On the bifurcation diagram of case #861497 there is a range of values supporting tristability of bursting, dep1, and hyp1 regimes (Figure 4B). Here, we used the original database value,  = 8.0 nS. A: the neuron exhibits steady bursting. B: the neuron exhibits slow damped oscillations towards the hyp1 stationary state. C: the neuron transiently fires spikes damping onto the dep1 stationary state.
