Gradient Trigger Mechanisms Related to Bistability Regimes in a Leech Heartbeat Model
Y. Zh. Guan, Sh. Q. Liu, and Y. J. Zeng

We studied bursting patterns underlying bifurcation phenomena and chaotic spiking in a computational leech heartbeat model. We observed the gradient physical properties of the ISI series and amplitude (shift of the membrane potential) when the parameter gleak  was mildly changed and found different bistable areas. The resulting computation implies that (i) classification of the intensity of the input /Uploads/file/20190222/2019022222130656656.pdfinformation is feasible in this regime, (ii) a neuron’s working level can be marked by its range in a 
typical bifurcation, and (iii) there are invisible triggers underlying subtle mechanisms in the model
